I have uploaded some files (images) which I'd like to link in my own site as well as other places, but usually I try to host a different resolution of the same image to show up on other sites. My problem with wordpress right now is that if I upload the file to Wordpress' upload directory through FTP, I don't see the file show up in my media (in WP-admin). I can get a link from my ftp client (cyberDuck) but it doesn't actually link me to a working link, also the link is something like this: <code> http://ftp.mydomain.com/really-link-file-name-with-20%-and-at-the-end-its.jpg </code> So I assume it works like that b/c it contains jpg at the end but it doesn't work and takes me to a 404 page. Any ideas of how I can go about uploading through an FTP client and get those files to show up on wordpress and also link correctly? | If I upload the file to Wordpress' upload directory through FTP, I don't see the file show up in my media (in WP-admin) Try to avoid directly uploading via FTP. WordPress doesn't scan your uploads folder for new images. Instead, use the built-in media uploader within WordPress to upload images. WordPress will automatically place them in the correct folder, create downsized versions you can use in a quick gallery or client sales page, and store the image's meta information in the WordPress database. The Media Gallery pulls its information from the WordPress database, so to see your uploaded images here, this is the only way to do it! I can get a link from my ftp client (cyberDuck) but it doesn't actually link me to a working link Your client is giving you an FTP link. If you use an FTP link in a web browser like Internet Explorer (i.e. ) your browser will act like an FTP client and try to download the image rather than displaying in in the browser. What you need is an actual HTTP link, which you can get from WordPress if you uploaded through the Media Gallery. If you uploaded directly via FTP, your link would still be something like http://www.mydomain.com/wp-content/uploads/2010/11/something-something.jpg if you uploaded to the <code> /wp-content/uploads/2010/11/ </code> directory. If you put it somewhere else, change the link accordingly. To Review The correct way to add images to WordPress and get the links is through the Media Gallery: Log in to WordPress Go to Media » Add New Select your image and upload it to WordPress Set meta data as appropriate (Title, Caption, Alt Text, Description) If necessary, you can Edit the image as well (rotate, crop, scale) Highlight the File URL and copy-paste it somewhere where you'll remember it. This is the URL to the full-size image that you can link to from other places. | How do I link directly to uploaded files? | wordpress |
I have been having an issue with the non-flash version of the NextGen Slideshow on my website. The slideshow seems to initially load the first slide about 5px below the desired position. The slide then moves up about a second or 2 later into the correct position. I have tried putting the slideshow in other widget areas and all result in the same positioning error. The page in question in here: www.ukjiayuan.com So far have been unable to get any support, but would really appreciate it if anyone can reccomend a solution. Many Thanks | Someone has just answered the question for me on the wordpress forum. It turns out that there was 5px of padding in the gallerys css file (line 301) that I hadn't found: .ngg-widget, .ngg-widget-slideshow { margin:0; overflow:hidden; padding:5px 0 0 0; <--- change this to 0 0 0 0 or just 0 text-align:left I didn't add this, so it seems like the css have been like this in the first place. So if anyone else has this problem in the future just change that 5 to a 0. | NextGen Gallery Slideshow Positioning Issue | wordpress |
In the text editor, where you can set headings and other settings, is it possible to add your own styles for clients to use? and even remove the unnecessary ones? | The "classic" TinyMCE editor has two dropdowns: <code> formatselect </code> for paragraph styles and <code> styleselect </code> for character styles - which can also contain paragraph styles, to make it more confusing. The configuration in WordPress by default only shows the format dropdown. If you apply a custom stylesheet to the editor, TinyMCE can use it to pick up the classnames and add them to the style dropdown - but this did not work every time for me. Since 3.0 you can call <code> add_editor_style() </code> in your <code> functions.php </code> to add a stylesheet to the editor. By default it's <code> editor-style.css </code> in your theme directory. Before 3.0 you have to hook into the <code> mce_css </code> filter to add the URL to your editor stylesheet. This will end up in the <code> content_css </code> TinyMCE configuration value . To add the style dropdown, the <code> styleselect </code> option must appear in one of the button bar configuration arrays ( <code> theme_advanced_buttons[1-4] </code> in TinyMCE, filtered by <code> mce_buttons_[1-4] </code> in WordPress). The list of block formats is controlled by the <code> theme_advanced_blockformats </code> option of TinyMCE , which you can add to the control array in the <code> tiny_mce_before_init </code> filter. If you want to customize the names of the style dropdown (not just your CSS class names), look at the <code> theme_advanced_styles </code> option . You can also use the more advanced <code> style_formats </code> option which gives you more flexibility to define the styles. The relevant PHP code with all the hooks and default configuration is in <code> wp-admin/includes/post.php </code> , in function <code> wp_tiny_mce() </code> . All together, your setup could look like this: <code> add_action( 'after_setup_theme', 'wpse3882_after_setup_theme' ); function wpse3882_after_setup_theme() { add_editor_style(); } add_filter('mce_buttons_2', 'wpse3882_mce_buttons_2'); function wpse3882_mce_buttons_2($buttons) { array_unshift($buttons, 'styleselect'); return $buttons; } add_filter('tiny_mce_before_init', 'wpse3882_tiny_mce_before_init'); function wpse3882_tiny_mce_before_init($settings) { $settings['theme_advanced_blockformats'] = 'p,h1,h2,h3,h4'; // From http://tinymce.moxiecode.com/examples/example_24.php $style_formats = array( array('title' => 'Bold text', 'inline' => 'b'), array('title' => 'Red text', 'inline' => 'span', 'styles' => array('color' => '#ff0000')), array('title' => 'Red header', 'block' => 'h1', 'styles' => array('color' => '#ff0000')), array('title' => 'Example 1', 'inline' => 'span', 'classes' => 'example1'), array('title' => 'Example 2', 'inline' => 'span', 'classes' => 'example2'), array('title' => 'Table styles'), array('title' => 'Table row 1', 'selector' => 'tr', 'classes' => 'tablerow1'), ); // Before 3.1 you needed a special trick to send this array to the configuration. // See this post history for previous versions. $settings['style_formats'] = json_encode( $style_formats ); return $settings; } </code> | can I add a custom format to the format option in the text panel? | wordpress |

When i try to access my domain mapping page it asks me to move the line define('sunrise', 'on') above the last require_once line in the wp-config file. It is already above this line. I tried moving it higher and even to the top of the file(below the opening I recognizes if i remove the line alltogether (asks me to uncomment the line or add it if it is missing) so I know It is not looking at some other file. What could cause this behavior? http://pastebin.com/wTWhxPjj | Apparantly this happens with the newer version of domain mapping because sunrise.php itself needs to be updated.

Is there a good WordPress book intended for graphic designers? I've started working with a friend in an arrangement where he designs a site and I build it in WordPress. This works great since I have the design sense of a blind monkey. He would like to learn more about WordPress and how best to design for it. I'm familiar with several good WordPress books, but most of them are intended for designer/developers. I'm looking for something that will serve as a guideline, offering suggestions for design conventions that are well suited to WordPress. Are there any such books? If there's not a book specifically aimed at designers, which other book would you suggest? | Some said this rockable book is awesome, though I don't buy it myself.

In my functions.php, I have a need to list all images in the uploads folder which are not currently attached to a post in the WP database.

I want to create a loop where 2 or 3 items from my blogroll are spliced in like this: <code> <loop> <post1> <post2> <blogroll1> <post3> <blogroll3> </loop> </code> I'll be using images and excerpts for the loop, and the goal is to get the <code> wp_links </code> links to display EXACTLY like the <code> wp_posts </code> , so if I can actually splice in the links to the <code> $post </code> variable somehow and loop over them AS IF they were posts, that would be great. Getting the posts via <code> get_bookmarks </code> is easy, but how would I fake WP into thinking they're <code> $posts </code> and how would I splice them into the <code> $post </code> object? | Thanks to everyone. Here is the solution that I ultimately ended up with. Rather than messing around in the loop itself, I chose to hook into <code> the_post </code> with a function that recreates the markup of the loop using data from <code> $links </code> . <code> <?php global $links; global $links_count; $links = get_bookmarks("limit=5"); function dg_archive_insert_links(){ global $post; if (!is_singular()){ add_action('the_post', 'dg_insert_links'); } } add_action('wp', 'dg_archive_insert_links'); function dg_insert_links(){ global $wp_query; global $links_count; global $links; if ( ($wp_query->current_post % 3) == 0 && ($wp_query->current_post > 0) && $links[$links_count]->link_url): ?> <div class="post type-post hentry"> <h2><a href="<?php echo $links[$links_count]->link_url; ?>" rel="bookmark" title='Click to read: "<?php echo $links[$links_count]->link_name; ?>"'><?php echo $links[$links_count]->link_name; ?></a></h2> <?php if ($links[$links_count]->link_description): ?><div class="entry-summary"><?php echo $links[$links_count]->link_description; ?></div><?php endif; ?> <?php if ($links[$links_count]->link_image && $links[$links_count]->link_description): ?> <a href="<?php echo $links[$links_count]->link_url; ?>" rel="bookmark" title="<?php echo $links[$links_count]->link_description; ?>" class="post_thumbnail" ><img src="<?php echo $links[$links_count]->link_image; ?>" width="150px" alt="<?php echo $links[$links_count]->link_description; ?>" /> </a> <?php endif; ?> </div> <?php $links_count++; endif; } </code> There's no need to create a new var to count, since it already exists at <code> $wp_query->current_post </code> | How to splice in wp_links links into the loop? | wordpress |
I'm writing a plugin that creates and handles a simple form. This has been my approach sofar, but it's turned out to have some major flaws: 1) On plugin activation, create a blank page for the form at mysite.com/form, and another blank page to process the form at mysite.com/processform. (They need to be separate pages with distinct URLs so that submissions can be tracked via google analytics. Otherwise, I'd just do all this via AJAX. I know, I know... not my decision.) 2) On the "wp" action, check to see what page we're on. 2a) If it's my form page, add a "the_content" filter to render the form (it needs some dynamic hidden elements like a nonce, which is why I didn't just include the form markup when I created the form page originally). 2b) If it's my processform page, add a "the_content" filter to process the POST and render any feedback. The major problem is with my POST handling. I'm hooking it to the "the_content" filter (because I need it to supply feedback), but this filter is sometimes run multiple times during a page load, causing the POST to be handled multiple times. I've included what I have below, but I can't help thinking I'm completely on the wrong track with my approach. How would you create and handle a form with your plugin if you needed it to hit a success URL (ie. not via AJAX)? My code: <code> <?php // On activation, create the blank pages function my_form_install() { // CREATE THE FORM PAGE $page_markup = ''; $arr_page_options = array( 'post_status' => 'publish', 'post_type' => 'page', 'post_author' => 1, 'post_title' => 'Form', 'post_content' => $page_markup, 'comment_status' => 'closed' ); // CREATE THE FORM PROCESSING/SUCCESS PAGE $success_page_markup = ''; $arr_success_page_options = array( 'post_status' => 'publish', 'post_type' => 'page', 'post_author' => 1, 'post_title' => 'Form Process', 'post_content' => $success_page_markup, 'comment_status' => 'closed' ); } register_activation_hook(__FILE__,'my_form_install'); // On the wp action, check to see if this is one of our pages. If so, add our filters. function check_current_page($obj_wp) { if(isset($obj_wp->query_vars["pagename"])) { $page_name = $obj_wp->query_vars["pagename"]; switch($page_name) { case "form": add_filter('the_content', 'my_render_form'); break; case "form-process": add_filter('the_content', 'my_process_form'); break; } } } add_action('wp', 'check_current_page'); // Function to render the form function my_render_form($page_markup) { $page_markup .= '<form method="post" action="/form-process"> <input type="text" name="some_input_field" /> <input type="submit" value="submit" /> </form>'; return $page_markup; } // Function to process the form function my_process_form($page_markup) { if($_POST) { // Do the form processing. This would involve many possible returns, // but I've just included one to simplify thigns. $page_markup .= 'Your form has been processed.'; } return $page_markup; } ?> </code> | That's just a quick feedback: Use a shortcode to insert your form into content. Those are quite flexible. And for the processed form's need to have another URL you can add a rewrite endpoint like /form/processed/ you can check after submission then. That's probably more modular. In the end that prevents you to deal with the <code> the_content </code> filter as you can deal with anything within the shortcode callback. It's a rough suggestion only, but probably does the job for you. | Best Practices for Creating and Handling Forms with Plugins? | wordpress |
I asked this before over at the WordPress forums some time ago, before WP3 with MU was released and I think it's relevant that I ask it again, here instead, cause of WP3. Basically I want to have my personal website and blog both powered by WordPress, the website should be at www.domain.com (or domain.com) and the blog at blog.domain.com. My first idea is to use 2 WP installations with the same exact theme sharing the same database. This would easily allow me to share content between the two. Like displaying the latest blog posts in the front page of the website, for instance. It would also allow me to easily maintain different content for each site with appropriate links for each page. What I meant is, a blog post should be accessed like <code> blog.domain.com/article/blog-post-title </code> and not <code> www.domain.com/article/blog-post-title </code> ; the same way, a main site page should be accessed like <code> www.domain.com/about-me </code> and not <code> blog.domain.com/about-me </code> . But two installations come with a few problems too... Double the work for maintaining WP updated to the latest version along with plugins. In case I need user registration for comments, two would be needed and I don't think the users will like that. I'm sure there are more problems, but this is what I can think of right now. So, does WP3 come with any feature, like MU, that could help me achieve what I want or my best and easiest bet is to go the double installation route? | You would just need to use the multisite functionality now in WordPress, see http://codex.wordpress.org/Create_A_Network . Setup the site to use the subdomain install. You would then setup the main blog to be your site, ignoring the posts section for that site. Then setup a new site within the Super Admin menu and set the subdomain for the new site to be blog.yoursite.com. You can then write blog posts from this new site while keeping the site navigation in the root install. | One WordPress install for main site at domain.com and blog at blog.domain.com? | wordpress |
I have seen many professional wordpress themes for sale that have shortcodes built in with which you could easily make posts like this: <code> [alert_box]This is an alert box which based on this short-code automatically switches the CSS so it is easier than messing with classes every time[/alert_box] </code> How can I do this?

I was wondering this, too. I tried and spent quite a few hours trying, but I was finally able to proceed. I discovered a few things that won't be obvious to most people along the way, so I'm posting some steps here. You should be able to have this set up on a test server for a test yourself in no time. If anyone has found an alternate way to do it, please let me know. First, I had wanted all of my bookmarks to be organized somewhat, and though there are some tagging extensions for firefox, a lot of them seemed too bulky. In retrospect, I could have tried some of them first. I chose to use <code> delicious.com </code> (formerly <code> del.icio.us </code> ) to tag my bookmarks for me. It seemed the simplest way to go about it, and most of the 1,500 bookmarks I had were known to that site, so tags were available. You will be able to use the firefox delicious extension, or import directly to their website. They have an API, and hidden inside it is this URL <code> http:// username:password@api.del.icio.us/v1/posts/all </code> which should get you to having your bookmarks, now with tags, as an xml file. Next, you'll use the script from here http://memografia.com/wordpress/delicious-to-wordpress-importer/ to import it as a blog. But you can't put this script in your plugins directory and make it work! WordPress 3.0 changed the way they do the importers, BUT they left in some legacy support (though this isn't really documented anywhere.) Simply make folder named 'input' in the wp-admin folder and drop the delicious.php file in there. (This works with any importer script that uses the register_importer() function.) Now when you go to your dashboard and look under Tools> Import you'll see that Delicious is an option. You can import the bookmark tags as categories or tags and it'll make a post for each bookmark. If anyone tries this out I'd love advice on what to do next. I reseached how to do this so I could get a handle on my bookmarks and comment on the ones that were most useful. I can do that, but if anyone knows of any plugins that would grab excerpts to flesh things out, please let me know. It is rather neat to have an archive of your bookmarks that can easily be sorted by time. | To be ON TOPIC on the QUESTION (firefox) i dont think the approach to use delicious as intermediate step is preferred because: you lose the hierarhical taxonomy applied in firefox (they way you structured things) you lose the favicons as gathered in firefox you lose the information added by dividers between links you lose information on the order of directories and urls applied in firefox it is not compatible with other sources of bookmarks e.g. other browsers and e.g. a directory of urls Therefore my approach is to a) export firefox to a "BOOKMARK" directory structure with each bookmark saved as URL. b) this bookmark directory is the actual heart and can be filled from other browsers, holds the hierarchical information and inside the .url files additonal meta information can be placed. (At this stage I dropped the divider export in my current code) From WordPress you can traverse through the directory structure an place it in WP. What you will notice is that the links as currently in WordPress also lose the applied directory taxonomy (e.g. no hierarchical categories) and have no good meta table therefore I have chosen to make a side table for my link storage to retain this information (see other answer for steps after that). The following might be the thing needed if you want to focus on exporting firefox first. once again: traversing through a physical directory and then reading this in e.g. a database table (wplinks) is out-of-the-box: <code> require_once("class-EdlSqliteDb.php"); require_once("class-EdlUtil.php"); class EdlFirefox { const BOOKMARKTYPE_URL = 1; const BOOKMARKTYPE_DIRECTORY = 2; const BOOKMARKTYPE_DIVIDER = 3; const FMODE = 0777; const DIVIDER = '--------------'; var $use_cache = true; var $dbh; public function __construct($DbLocation, $ffRoot, $exportLocationBookmarks) { $this->mDbLocation = $DbLocation; $this->mRootTitle = $ffRoot; $this->mExportLocation = $exportLocationBookmarks; // database settings $this->dbh = new EdlSqliteDb($DbLocation); $this->dbh->addQ(1,"SELECT id FROM moz_bookmarks WHERE title=?"); $this->dbh->addQ(2,"SELECT id, title, type, fk FROM moz_bookmarks WHERE parent=?

So you need both the domain structure and the relative url structure and have each single node of every possible url (both domain and relative) as an entry in the database to be able later to represent this and enrich this and you need the relations between each part in the url to be able to represent it. I have written a class that loads in the official TLD structure and used this as root items in my database. So .uk gets the id 1 and .co.uk get a parent id 1. I used both the Mozilla list and other: source is the Mozilla Public Suffix List: http://publicsuffix.org/ but that is a bit outdated so you need to add to it Now that I have the official TLD's in there I have class that loads in the Alexa top 1.000.000 sites. This will link in the same way. Many of these are a sort of unofficial top level TLD's. Since e.g. "google.com" is not as official as the TLD of some country but it seems more important. By doing that you will discover some patterns but also some exceptions e.g. you will find IP addresses that are populair. Each of these entries fills the field "Alexa Ranking". (for performance I first load the .csv in a help table) Alexa will force you to review the patterns so that is good (a good test set) I have written a class that traverses my Firefox Databases (sql lite) and exports all urls in there as .URL in a hierarchical directory structure. It also exports the favicons whether they be .ico, .png, .gif etc... (see below). This is also read in the database. Since I update this a lot it sycns with the database described in 1 and 2. (in the beginning I also exported the dividers but I stopped doing that). I have begun to just drag and drop bookmarks in this directory structure from other browsers e.g. from chrome I just drag a bookmark from the browser to the directory which also delivers that .url file. The directory structure of URL's I have given extra properties e.g. (h) at the beginning of the name will lead to a "heart" e.g. one URL I particuarly like and #01# will place it at the top (or at least thats the way code further on handles it). I have placed this directory structure in a dropbox. I still have to write the code on the server to be in constant sync so the dropbox server part. (My WORDPRESS on the server counterpart constantly reads the URL directory structure for syncing and updating bookmarks as above but i now use ftp sync) I have written classes for delicious (you need a MD5) and StumbleUpon to get not only the ranking (delicious=amount of bookmarks) (SU= amount of reviews and amount of pageviews) but also the TAGS and the description people use (why should I invent my own tags if people have already given them). Since you have a limit amount of calls you can do to these systems you need to spread it over time to enrich your database. (if you now go to delicious and look up a link see the right side and get an idea about the taxonomy of tags given to links) I use the Google favicons provider (const GOOGLE_ICON_URL = 'http://www.google.com/s2/favicons?domain=';) to show the favicons BUT since Google does not have all the icons (e.g. not for facebook applications) I enrich the cache with the icons I exported from Firefox. For that you need a priority system build in which chooses the correct favicon over the other. To cache this I have a caching structure that looks like the domain reversed for the . parts e.g. .com.facebook.apps.geochallenge and on a deeper level the relative path structure. In eeach directory in that cache structure I store the cache favicons. In a previous release I also store there the results of the calls to delicious and stumblupon. It seems that this is WordPress out-of-scope but in fact (grin) it is very in-scope. The build-in link functionality has no good meta options / no meta table and it has some more restrictions like no hierarchical categories etc... Also you need to type in information in it itself while there are a lot of services which already categorize urls (e.g. dmoz) and give it tags etc... which have become sort of default. So this lies "under" my WordPress site for handling my links. I am making this setup with all the information of at least the top 1.000.000 plus sites to make the amount of calls less and to later on share this as a plugin. I have a stumbleupon plugin in the wp plugin db and that led to this. It can give you information on the external links you have in your weblog. There are a lot of plugins that give you information on SEO general but none which show you reports and comparions of e.g. ´what percentage of your outgoing links is in which category or popular or not etc..´. It also gives rankings to your incoming links and outgoing links etc. etc. | Wondering how to turn your firefox bookmarks into a WordPress blog? | wordpress |
Anyone know of a way to deregister custom post types ? Is there an equivalent to register_post_type() ? | Currently there is not a function for unregistering a post type, the process however is quite simple. Andrew Nacin provided some code over on trac, found here and posted below. <code> if ( ! function_exists( 'unregister_post_type' ) ) : function unregister_post_type( $post_type ) { global $wp_post_types; if ( isset( $wp_post_types[ $post_type ] ) ) { unset( $wp_post_types[ $post_type ] ); return true; } return false; } endif; </code> Unregistering a built-in post type will have unknown effects on WordPress, so please do so at your own risk. Unregistering a custom post type should be perfectly safe, but would naturally do no cleanup on your installation(ie. unregistering a post type does not equate to data removal from the database). I can imagine a few scenarios where this could be required, but the more sensible approach(where possible), would be to simply not register the post type in the first place if it's not wanted. | Deregister custom post types | wordpress |

With WordPress 3.0 its easy to for users to submit custom content from the front end. They don't even need to be logged in anymore.

Thanks! | I don't know the name of a function that would do just that - but i can give you what i think is a good algorithm to do so However, I suggest you do the following trick : Once the user publishes new content - let it have a category called "user submission" for example or any other stuff Once an admin views the post, he can remove that category and label the content accordingly. So all you have to do is use feedburner or any email notification system to let the people you want know about the "new posts" or RSS subscription by category to do by programming : 1 - you have to fetch the user details for which users are admins from the tables users/usermeta 2 - in some separate table, you must have lastPostId, AdminId 3 - write a script get the posts that have an ID > lastPostId and send the email 4 - this script can be run using a cron job | Notify admin on new submit | wordpress |

( Moderator's note: The original title was "Custom User Role Restrictions") A project I am working on requires me to create two new user roles - one for the owner of the website and the other for agents of the company. With the website owner user role I was just looking for a way to restrict users in this group from modifying core site settings while having access to modify all other settings. The code below seems to work perfectly for everything other than the user management area. I did want users of this group to be able to add/modify website users BUT where I am running into a problem is that users of this group currently have the ability to create users in the "Administrator" category and they are also able to deleting existing "Administrators" .

I have a plugin that restricts the categories users can view/edit in the admin. All works fine in WordPress 3.0.1, but as I started testing 3.1 I noticed that the category filter, which is AJAX, allows you to bypass the restrictions.

I created a separate template, attachment.php, for displaying image attachments. It's relatively simple; basically a stripped down version of single.php. Everything is working great except that when I have the All in One SEO plugin enabled (and set to rewrite titles), the titles on those attachment pages are being doubled. For example, this attachment 's title should be "11 hours of MacBook Air battery life", but the title tag is being rendered as "11 hours of MacBook Air battery life 11 hours of MacBook Air battery life" This only happens on the attachment.php pages, not on the rest of the site's normal posts and pages. Any idea what could cause that? | The problem is the way that All in One SEO is set up. It assumes that you always attach your media files to a post or page. Simple way is to attach them to a post or page and it will make your attachment title be "PostName AttachmentName - Blogname". The other way is also easy, but you have to make a change to the plugin. You open up the aioseop.class.php file, and find this chunk of code: <code> else if (is_attachment()) { $title = get_the_title($post-> post_parent).' '.$post-> post_title.' – '.get_option('blogname'); $header = $this-> replace_title($header,$title); } </code> The problem with this setup is that it grabs the parent whether or not it is a child. If it has no parent, its parent title is its own title, hence the double title. To remedy this, we can add an if statement to check whether or not it has a parent to avoid the double title. So the code would look like this: <code> else if (is_attachment()) { if(get_the_title($post-> post_parent) != $post-> post_title) { $title = get_the_title($post-> post_parent).' '.$post-> post_title.' – '.get_option('blogname'); } else { $title = $post-> post_title.' – '.get_option('blogname'); } $header = $this-> replace_title($header,$title); } </code> Then you just upload this to the All in One SEO plugin folder and your problem should be fixed.

Is it now possible to query multiple categories from the URL? http://www.mywpsite.com/?cat=1+7 ? I think this has worked for tags for some time . If not, is there another way to achieve this? | If you have a feature request for WordPress, the best way to get it addressed is to add a ticket on Trac. Then developers can adopt the task, patch WordPress, and submit the improvements to the next version.

Install the WordPress Beta Tester plug-in and upgrade to version 3.1-alpha. This would be the safest way to use the new feature, but still might cause problems! WordPress 3.1 isn't considered "stable" yet and some of the features/code might (will definitely) change before the final release date.

Is there an easy way to query for any posts that is tagged with any term from a particular taxonomy? I know this technique: <code> $custom_taxonomy_query = new WP_Query( array( 'taxonomy_name' => 'term_slug', ) ); </code> But I would like to either pass a wildcard in place of term_slug, or perhaps just an empty string. Then that would give me all posts that are tagged by any term in that taxonomy, not just one specific term.

I have a client who wants to use Joomla, because they were told it was good. I'm trying to convince them that WordPress is a much more user-friendly option. I've played with Joomla (and Drupal) once before, and I found the learning curve incredibly steep (probably due to their obscure terminology). I consider myself quite technically savvy, and if I found it hard, I'm sure my less technically competent clients will find it even more obscure and difficult to learn. So far, I have yet to come across anything a client would need that couldn't be done in WordPress, but before I tell them that, I wanted to check that this is, indeed, the case. Is there anything that Joomla or Drupal can do that WordPress can't (especially now with custom post types in WP 3+)? | If memory serves, Drupal's lead dev summed things up like so last summer: Drupal is, on the UI front, where WP was 3 years ago; and WP is, on the feature front, where Drupal was 3 years ago. My own experience with WP and Drupal are basically so: WP has a prettier/easier UI. Drupal is more robust: core and add-on devs are rarely writing code to learn PHP. WP is still stuck in old PHP4 paradigms. Drupal isn't. WP development is still not unit-test driven. Code quality is, at best, inconsistent. Drupal is mostly EAV-driven. This makes things much more flexible... and slow for anything requiring complex queries. (Drupal compensates this by having built-in caching.) WP is heading in the same direction. I can't really say for Joomla. I dismissed it years ago because I hated the UI. But everyone here probably has a trustworthy friend who is very happy with it. As to what I tend to use: For a blog or a simple brochure-like site, definitely WP. For a slightly more complex site, also WP -- but an inner voice always tells me I should be using Drupal instead. For anything really complex and mission critical, a unit-test driven PHP framework (Symfony, Solar, Yii...). UI will end up so so, but I like to sleep at night. | Is there anything that Joomla or Drupal can do that can't be done in WordPress? | wordpress |
I am using a plugin the updates the option table using update_option command. When I update content with hebrew characters it turns into gibrish. My database does support hebrew (or any other utf8 chars). Is there any workaround? Thank you! | Chances is are that the content-type/charset header is not being sent, and that you end up reading the utf8 chars as if they were latin-1. Also, note that serialize()/unserialize() are not multibyte character-safe. For a subset of characters, the string's length as returned by serialize() will occasionally differ from the expected length as it would be returned by mb_strlen(). This leads to all sorts of hard to debug unserialize problems which, since around WP 2.8, WP tries to discard in order to avoid crashing sites. | update_option method with support of utf8 | wordpress |

I am trying to build a class to make the job off adding new settings easier. The trouble I am having is that, although I have traced the variable through all of it's stages, the string 'manage_options' doesn't seem to grant admin the right to amend and option. I keep getting "You do not have sufficient permissions to access this page." when I try access the new settings page. Here is a heavily simplified version of the class, the creation function and its action hook. <code> class optionObject{ var $user_level = 'manage_options'; function add_page() { add_options_page(menu_page_title, page_title, $this->user_level, menu_slug, array(&$this, 'do_page')); } function do_page(){ //do stuff to display page } } function test_options(){ $options = new optionObject(); add_action('admin_menu', $options->add_page()); } add_action('admin_init', 'test_options' ); </code> Unedited Version here | <code> admin_init </code> is called after <code> wp-admin/menu.php </code> is included , so the access check has already been executed and the <code> admin_menu </code> action has fired by the time you execute <code> test_options() </code> . Remove the <code> admin_init </code> hook and call <code> test_options() </code> directly, or find another way of structuring your code so that the <code> admin_menu </code> hook is set up correctly. You might think it could work because you see the menu option when you are on other pages. This is because the menu is drawn after the page access is checked : The menu is drawn in: <code> wp-admin/menu-header.php </code> on line 169 included in <code> wp-admin/admin-header.php </code> on line 143 included from various places, but always after <code> wp-admin/admin.php </code> line 132 which is after <code> admin_init </code> fires in <code> wp-admin/admin.php </code> on line 98 The access check however is done in: <code> wp-admin/menu.php </code> on line 441 which is after <code> admin_menu </code> fires in <code> wp-admin/menu.php </code> on line 328 which is included in <code> wp-admin/admin.php </code> on line 93 You see that adding menu items in <code> admin_init </code> is OK to be included in the drawn menu, but too late for the access check. That's your current situation, and you need to change that by adding the page in the <code> admin_menu </code> hook or earlier. | add_option_page capability behaving strange | wordpress |

After reading stackexchange-url ("Adding a Taxonomy Filter to Admin List for a Custom Post Type?") I tried it but I wasn't able to get it to filter two (2) different taxonomies at same time. The system is only filtering latest taxonomy and ignoring other one. Does anyone know how to filter two taxonomies at same time? | Hi @Ünsal Korkmaz: I don't have the time to actually write up a fully working example for you right now, but since you requested help in email I figured I would point you in the right direction. As you may or may not know, this isn't really an issue for the admin post listing; most all of that code should work fine. The issue is that currently WordPress does not have the ability to use <code> query_posts() </code> / <code> get_posts() </code> / <code> WP_Query </code> to filter on more than one taxonomy term without using hooks. (There is a very good chance that will change in v3.1; we can only hope!) The solution is to use a <code> 'posts_where' </code> hook as illustrated here with the <code> tax_terms_where() </code> function written for that answer: <a href="stackexchange-url Getting the Intersection of Two Custom Taxonomy Terms for a Custom Post Type? You'll also need to modify the <code> 'parse_query' </code> hook to capture your filter values, something like this (I have not tested this, so there may be small syntax errors): <code> <?php add_filter('parse_query','yoursite_parse_query'); function yoursite_parse_query($query) { global $pagenow; $qv = &$query->query_vars; if ($pagenow=='edit.php') { $tax_terms = array(); if (!empty($qv['marka'])) $tax_terms[] = "marka:{$qv['marka']}"; if (!empty($qv['konu'])) $tax_terms[] = "konu:{$qv['konu']}"; if (count($tax_terms)) $qv['tax_terms'] = implode(',',$tax_terms); } } </code> The above assumes you have dropdowns with names of <code> 'marka' </code> and <code> 'konu' </code> . You'll probably also need to tell WordPress to recognize them as query vars using an <code> 'admin_init' </code> hook. Again, I haven't tested this so I'm hoping it works as written: <code> add_action('init','yoursite_init'); function yoursite_init() { global $wp; $wp->add_query_var('marka'); $wp->add_query_var('konu'); } </code> That's about it. Combine the knowledge of the three posts; this one, the one on stackexchange-url ("admin lists"), and the one on stackexchange-url ("multiple taxonomy queries") and I think you'll get it done. You might even want to post your solution for others to learn from. Let me know if you get stuck. | Filtering Posts by Multiple Taxonomy Terms such as in an Admin Post Listing? | wordpress |
I've got a small .js file on my wp site where I have been adding in all of my small js scripts. It works perfectly, but I am stuck trying to figure out how to add in another script. So far jslint does not complain about my current file and says it is ok. my script: <code> jQuery(function ($) { function mycarousel_initCallback(carousel) { jQuery('.jcarousel-control a').bind('click', function() { carousel.scroll(jQuery.jcarousel.intval(jQuery(this).text())); return false; }); jQuery('.jcarousel-scroll select').bind('change', function() { carousel.options.scroll = jQuery.jcarousel.intval(this.options[this.selectedIndex].value); return false; }); // Next Button $('#mycarousel-next').bind('click', function() { carousel.next(); return false; }); // Prev Button $('#mycarousel-prev').bind('click', function() { carousel.prev(); return false; }); }; } </code> The script I want to add in starts like this: <code> jQuery(document).ready(function($) { var gallery = $('#thumbs').galleriffic({ delay: 3000, // in milliseconds }); }); </code> Where I keep getting stuck, is that I am finding a lot of scripts that start with the jQuery(document) part. When I try to add scripts that begin like that then everything breaks. I'm guessing this is a really stupid question, but what do I need to change in the new addon script so that it will play nice with my current file? thank you for your help and time on this one. Trying hard to learn js though it's a slow process here. | The <code> jQuery(document).ready </code> event is called when the document DOM is ready to be manipulated. In earlier days we attached all our handlers to <code> document.load </code> , but this waits until all images are loaded too, and most of the time one doesn't need that. There are three equivalent ways of hooking into this event, and a fourth almost-equivalent: <code> // Long form jQuery(document).ready(function() { // Your handler }); // Short form jQuery(function() { // Your handler }); // Intermediate form (not recommended) jQuery().ready(function() { // Your handler }); // Classic event binding - will not be executed again if you hook it too late jQuery(document).bind("ready", function() { // Your handler }); </code> You sometimes see <code> $ </code> used instead of <code> jQuery </code> . This is easy because it is shorted, but some other JS libraries use it also. To prevent overwriting others, jQuery can be executed in <code> noConflict </code> mode . This means that <code> $ </code> is not used, only <code> jQuery </code> is. But, the first argument to your <code> ready </code> handler will be the jQuery object itself. This means that you can write your handler like <code> function($) {} </code> , and you can use <code> $ </code> inside of your function. So your code would become something like this: <code> jQuery(function ($) { function mycarousel_initCallback(carousel) { jQuery('.jcarousel-control a').bind('click', function() { carousel.scroll(jQuery.jcarousel.intval(jQuery(this).text())); return false; }); jQuery('.jcarousel-scroll select').bind('change', function() { carousel.options.scroll = jQuery.jcarousel.intval(this.options[this.selectedIndex].value); return false; }); // Next Button $('#mycarousel-next').bind('click', function() { carousel.next(); return false; }); // Prev Button $('#mycarousel-prev').bind('click', function() { carousel.prev(); return false; }); }; // We are already in the 'ready' event handler, no need to hook into it again // Just add our code here! var gallery = $('#thumbs').galleriffic({ delay: 3000, // in milliseconds }); } </code> If you have more pure JavaScript questions, you might want to ask them on our "parent" site, stackexchange-url ("Stack Overflow").

I'm working on building a recipe/meal planning site in WordPress. I need to have recipes indexable and sortable by the ingredients required, and I'm trying to figure out the best way of doing that. Ideally, I would like to have ingredients in one taxonomy, and utensils/appliances required in another taxonomy. I'm coming up against a stumbling block, though, because I can't think of any simple way to associate measurements with the ingredients. Where I'm at now is using custom fields for the ingredients and values for the measurements and units, like this: Meta Key: eggs Meta Value: 3|eggs Meta Key: flour Meta Value: 2.75|cups and so on. My question is, is there a better way of structuring this information? Related, there apparently is a microformat specification for recipes , which is essentially the format I plan on using for display. There is a WordPress plugin ( hRecipe ) to generate this output format, but its not semantic enough for my liking. If/when I figure out a better way of storing this kind of data, I'll probably release it as plugin... | It's a good idea to use a custom taxonomy to link your ingredients, as this will allow you to get recipes by ingredient. This also means you don't have to store each individual ingredient as a separate meta key-value pair, as you won't do any lookups there. Just store one big object, <code> ingredients </code> , as an ordered list of ingredients and their quantities and units. Read it out when you display the page. So something like this: <code> $ingredients = array( 'eggs' => array(4), 'whole wheat flour' => array(1, 'cup'), 'baking powder' => array(1.5, 'teaspoon'), ); </code> You could also use the ingredient slug or id as the index of the array, then you can cross link from the ingredient list. By separating the number and the units, you can adjust the numbers for number of guests. Say your default is 4 and I have 6 guests, you just multiply everything by 1.5. You can even include a US to metric conversion! But I'll stop before this becomes a stackexchange-url ("Seasoned Advice") question! | Best structure for entering recipes in a WordPress theme? | wordpress |
I have a custom post type that i want to access through jQuery - preferably using JSON. So first things first. creating a function that returns/echos json is easy enough, but how would I access it through jquery. as Mike writes in stackexchange-url ("this question"), he - as far as I understand - places it in the wordpress root. which would make it accessable using the php file name - but Is this recommendable? I would rather put it inside a plugin folder. I have tried reading the wordpress codex, but the way ajax calls are handled just confuses me, as you are posting every ajax call to admin-ajax.php, even though it is not an admin page? Can someone please straighten out the problems I'm having? /Storm edit The problem I had was understanding how ajax calls were to be made in wordpress, as well as where to place your php and js code to do/handle the calls. In the other question I linked to, you created a function placing the file in the wp root - I dont want to do that. But I have now learned how to use the wp_ajax_(nopriv_)[action] and can effectivly access the json i create. The problem remaining is Where i should place the JS to make the call. I want to place it in the plugins js file, but as this is to be presented in a page, not on the admin site, ajaxurl isn't defined, so i have to echo using php. <code> echo admin_url('admin-ajax.php'); </code> So the question becomes how should I combine this php with the javascript, and how should i then enqueue it, seeing as it's not a file or a script. | Ajax Handler It is indeed a bit confusing that the Ajax handler is in the <code> wp-admin/ </code> directory, but yes, you can and should use it for non-admin requests too. You then register a handler for the <code> wp_ajax_nopriv_[action] </code> hook, instead of the normal <code> wp_ajax_[action] </code> . In this case you only have to follow the first lines of <code> admin-ajax.php </code> , since a request done by a user that is not logged in will already leave the page around line 50. So register a function for the hook <code> wp_ajax_nopriv_get_custom_post_data </code> , and it will get called if you ask for <code> admin-ajax.php </code> with the <code> action </code> parameter set to <code> get_custom_post_data </code> . Be sure to call <code> die() </code> at the end of your handler yourself, otherwise the default <code> die(-1) </code> will be returned. And also register the logged-in version, <code> wp_ajax_get_custom_post_data </code> (to the same handler function, no problem), since if you are logged in to your site, you will not hit the <code> nopriv </code> hook. Server-side config to Javascript The trick to send server-side configuration data (like the <code> admin-ajax.php </code> url), is <code> wp_localize_script() </code> . You pass it an array of keys and values which will be included in the top of the page. This was probably originally created only for localizable strings, but you can use it to pass configuration data too. <code> wp_localize_script('storm_json_config', 'storm_config', array( 'ajaxurl' => admin_url('admin-ajax.php'), )); </code> <code> storm_json_config </code> is the handle name (if you want to dequeue it later), <code> storm_config </code> is the name of the Javascript object that will contain your data. So your static Javascript file can contain a line like <code> jQuery.post(storm_config.ajaxurl, ...) </code> . See also stackexchange-url ("bueltge's answer to a similar question"). Static Javascript from the plugin dir To load a static Javascript file from your own plugin dir, you use <code> wp_enqueue_script() </code> . That would look something like this: <code> wp_enqueue_script('storm_json', plugin_dir_url(__FILE__) . 'js/json.js', array('jquery'), '20101105'); </code> Where <code> storm_json </code> is again a handle name, then you give the link to the file, then the dependencies (can be <code> null </code> ), and then a version number that will be added after the request to beat browser caches on updates. | How to manage ajax calls and JSON in wordpress | wordpress |

I am using a custom WordPress install (not WP hosted). | Use the "sticky" feature. In the "Page Attributes" metabox (labelled as Publish ), if you click the "edit" link next to the Visibility option, there is a checkbox which allows you to "Stick this post to the front page" .

In addition, it adds the class name "sticky" to the attributes returned by <code> post_class() </code> , so you can style it however you want. To add some text to your featured posts and highlight them, add a function like this inside the loop in your index.php (or loop.php, etc., depending on your theme): <code> if (is_sticky($post->ID)) echo '<span class="featured">Featured!</span>'; </code> You can do the same thing with the css :before property, like this: <code> div.sticky h2:before { content: "Featured!

I have a blog with some posts, and each post has a embedded Facebook like button . Pressing the button opens a dialog so my visitors can share the post on Facebook with a comment. When sharing, however, the image selected by Facebook is a generic mail icon and not the post thumbnail. How can I control the image that is used when sharing? | The image that is used for sharing is taken from a chunk of code in the header of your site that will look something like this: <code> <link rel="image_src" href="path/to/theme/screenshot.png" /> </code> Typically it links to the screenshot of your site in the theme. If you removed the code from the header of the file and on single.php put it inside the loop and called your post thumbnail image into the href element I believe it would work. So it would look something like: <code> <link rel="image_src" href="<?php the_post_thumbnail(); ?>" /> </code> This would mean that if you have like buttons on pages that list multiple posts you probably won't have an image. If you included some conditional code that removed it only on single.php then you would have the normal image on any page with multiple posts and an like button and the post thumbnail when the single.php template is being used.

I'd like to implement a similar functionality as WP Categories screen in the Admin area. Where you can add category and it will appear in the list of all categories straight away. I have a CD custom post type and I would like to add tracks to a CD in the same way as WP Categories are added. So that after general CD info there will be an empty "New track info" form where a track's info is inserted and after hitting "Add track" - a track will appear under the general CD info, and again displaying an empty "New track info" form to add another track to a CD.

I have an interesting problem I am trying to solve. Here is my situations: I have create a custom post type for "events". For each event post I require custom fields to be entered for the event start date/time. In addition, each event can be assigned to a custom taxonomy I have created specifically to assign each event to one or more "event categories" (my custom taxonomy). I have create a public template which calls all posts belong to this custom post type and am correctly filtering the query to ONLY display events were the event start/date and time is greater than todays date. All of the above is working correctly. The only thing I am currently having problems with is displaying all the events for a specific taxonomy term. In other words... along with each event listing I am including all terms associated with the event from my custom taxonomy (event categories). So, there issue here is that each taxonomy term (correctly) shows up as a link but when you select the term the corresponding terms archive page is not ordering the corresponding results by the event date/time custom field and it is not excluding events which are older than todays date. Based upon this page: http://codex.wordpress.org/images/1/18/Template_Hierarchy.png I have figure out that one is able to create a custom archive page for all terms belonging to a custom taxonomy by naming the archive file as follows: taxonomy-event_categories.php (where "event_categories") is the name for my custom taxonomy. Sooooooooo.... As mentioned the only thing I believe I need a solution for is the correct code to insert to achieve the two issues mentioned above. Here is the code I am using which works in display my event list correctly organized by the event start date/time while removing all events older than today. <code> <?php //Get the metadata for each child page global $custom_metabox_event_dates; $meta1 = $custom_metabox_event_dates->the_meta(); $today = time(); $arrMonthNums = array("01" => "01", "02" => "02", "03" => "03", "04" => "04", "05" => "05", "06" => "06", "07" => "07", "08" => "08", "09" => "09", "10" => "10", "11" => "11", "12" => "12"); $arrMonthNames = array("01" => "JANUARY", "02" => "FEBRUARY", "03" => "MARCH", "04" => "APRIL", "05" => "MAY", "06" => "JUNE", "07" => "JULY", "08" => "AUGUST", "09" => "SEPTEMBER", "10" => "OCTOBER", "11" => "NOVEMBER", "12" => "DECEMBER"); query_posts('post_type=events&showposts=-1&meta_key=' . $custom_metabox_event_dates->get_the_name('combined_datetime') .

Rather, somehow I need to get the archive page to recognize which term was clicked and essentially pass that through the query along with the ordering/filtering I am doing above. I am assuming this is probably a simple answer which involves the "loop" which I have yet to master. UPDATED Here is the code for the archive page which needs to be modified so when a term is clicked from the results list above so it ONLY shows the same results but only for the term selected AND sorted by date/time AND eliminating any events earlier than todays date. <code> <?php if (have_posts()) : ?> <?php $post = $posts[0]; // Hack.

This way you don't have to worry about the rest or the query options as they will still work. It should look like this (untested), and be placed in a plugin or theme functions file (not in the page template file, the query will already have been executed): <code> add_action('pre_get_posts', 'add_event_date_criteria'); function add_event_date_criteria(&$query) { // We only want to filter on "public" pages // You can add other selections, like here: // - Only on a term page for our custom taxonomy if (!is_admin() && is_tax('event_types')) { global $custom_metabox_event_dates; $query->set('meta_key', $custom_metabox_event_dates->get_the_name('combined_datetime')); $query->set('meta_compare', '>='); $query->set('meta_value', time()); $query->set('orderby', 'meta_value'); $query->set('order', 'asc'); } } </code> You define the scope of this extra filter with the contents of the <code> if() </code> test. Currently we don't do it on admin pages (you wouldn't be able to access old content), and only do it on specific taxonomy pages. You should find out for yourself how wide or how narrow you want this. If you can't solve it this way, you can do the main query again without losing the "page specific query" by adding the different query vars to the main <code> $wp_query </code> objects, and calling <code> $wp_query->get_posts() </code> again. Since we did not call <code> $wp_query->parse_query() </code> , the page-specific query args will not be cleared. It would look like this: <code> global $custom_metabox_event_dates; $wp_query->set('meta_key', $custom_metabox_event_dates->get_the_name('combined_datetime')); $wp_query->set('meta_compare', '>='); $wp_query->set('meta_value', time()); $wp_query->set('orderby', 'meta_value'); $wp_query->set('order', 'asc'); $wp_query->get_posts(); </code> You can place this in your template files (not <code> functions.php </code> , but <code> taxonomy-event_types.php </code> or other "real" template files).

Try: <code> wp_schedule_event(time(), 'daily', 'my_daily_event'); add_action('my_daily_event', array(&$this, 'my_widget_cron')); if ( !wp_next_scheduled( 'my_daily_event' ) ) { wp_schedule_event(time(), 'hourly', 'my_daily_event') } </code> If you remove the widget from the sidebar, the cron will still continue to run. You can run the following code (outside of the widget class) to clear it: <code> if ( !is_active_widget('your_widget_callback_function') && wp_next_scheduled( 'my_daily_event' ) ) { wp_clear_scheduled_hook('my_daily_event'); } </code> | Schedule cron event from widget | wordpress |
You can create a new page/post for this and set a custom publish date for it, but now the question is: How can you make a page to be available for a specified amount of time and replace it with something else after this? One usage example would be if you want to do a limited time offer and after this you want to replace or hide the page. As you can imagine I'm looking for a solution that would allow you schedule this, so you could be in vacation when the change happens ;) | If you made your special offers a custom post type you could set the 'scheduled' date to the day you wanted it to expire then use this code to auto publish it on schedule after you've changed the scheduled date. The 'future_show' line goes with my 'show' custom post type so if you had a 'deal' custom post type it would say 'future_deal'. <code> <?php function sfn_setup_future_hook() { // Replace native future_post function with replacement remove_action('future_show','_future_post_hook'); add_action('future_show','publish_future_post_now'); } function publish_future_post_now($id) { wp_publish_post($id); } add_action('init', 'sfn_setup_future_hook'); ?> </code> You can then set the post to expire if it's older than today on the server with the code below. It hooks into WordPress cron so you're not running it all the time but you'll notice a line commented out that runs it on init so you can test it. For testing comment out the first 3 lines and use the init action. Don't do this on production though. <code> <?php // setting posts with current date or older to draft if (!wp_next_scheduled('sfn_expire_hook')){ wp_schedule_event( time(), 'hourly', 'sfn_expire_hook'); } add_action( 'sfn_expire_hook', 'sfn_show_expire'); function sfn_show_expire(){ global $wpdb; $server_time = date('mdy'); $result = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_type = 'show' AND post_status = 'publish'"); if( !empty($result)) foreach ($result as $a){ $show_time = get_the_time('mdy', $a->ID); if ( $server_time > $show_time ){ $my_post = array(); $my_post['ID'] = $a->ID; $my_post['post_status'] = 'draft'; wp_update_post( $my_post ); } } // end foreach } // add_action( 'init', 'sfn_show_expire' ); ?> </code> Don't forget to change my function prefix (sfn) to your own just to sandbox it's function from anything else. Edit I just also thought that you could change the SQL query to grab posts in a category of 'deal' and it would work the same way.

Back in May, I recall seeing a post on the WordPress Development blog by Alex M (Viper007bond.com) where he added functionality for Automatic Ticket/Revision/Diff Linking which allows for linking to Trac tickets, Trac revisions, and Trac diff comparisons.

When you click on "Posts" or "Pages", you get a paged listing of your posts or pages with the following columns: Title | Author | Categories | Tags | Date I have a plugin which gives an SEO score for each post and page. I would like to add two columns to the list view when viewing posts or pages, one for the post's "seo score" and one for the posts "seo keyword" so that the column listing becomes: Title | Author | Categories | Tags | Date | SEO Score | SEO Keywords | You add the column using the <code> manage_posts_column </code> filter , where you add two new array elements with a custom key name and the header name as the value. <code> add_filter('manage_posts_columns', 'add_seo_columns', 10, 2); function add_dummy_column($posts_columns, $post_type) { $posts_columns['seo_score'] = 'SEO score'; $posts_columns['seo_keyword'] = 'SEO keyword'; return $posts_columns; } </code> The function that displays each row, <code> _post_row() </code> , then fires the <code> manage_posts_custom_column </code> action for each column that it does not know.

I'm getting this message each time I activate my plugin: The plugin generated 80 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin. The only way I can suppress the message is to wrap my activation function code in a conditional (**see below). How should I rewrite this to prevent the alert? <code> function myPlugin($post) { echo "Whatever is here throws an unexpected output alert when the plugin isa activated"; //I can place code here without issue, but anything that is output via echo throws the alert. } register_activation_hook(__FILE__, 'myPlugin'); </code> Wrapping the function code in the conditional suppresses the alerts: <code> function myPlugin($post) { global $pagenow; if ( is_admin() && $pagenow !== 'plugins.php' ) { echo "No more alerts when its wrapped this way"; } } ?> </code> | Hi @Scott B : When you get this kind of message is usually means your plugin had a syntax error and was generating that kind of error messages because of how the loading on activation is handled, i.e. HTTP headers are sent after the error message is display. Your plugin's error message is loaded in an <code> <iframe> </code> ; have you done a "View Source" on the <code> <iframe> </code> to see if there's an obvious error message? Also, you should consider getting an HTTP debugger which can help with this kind of things: Windows has the excellent and free Fiddler . For Mac OS X there's HTTPScoop (not great, but inexpensive at US$15 .) There's also Charles for Windows/Mac/Linux ( US$50 - I may break down and buy it one day. Wish I could get Fiddler on Mac, but since Fiddler comes from Microsoft I don't hold my breath.) UPDATE Based on the comments below, here's a screen of me using "Inspect Element" in Safari (but you can do the same with Chrome and FireFox, or similar with IE and the Web Developer Toolbar): You can grab that <code> <iframe> </code> d URL and load it directly in your browser to make the process of debugging easier. Something in your plugin is sending q <code> header() </code> after an error message is thrown, that's what that error message means. BTW, I just added a stray character and hence syntax error in my plugin to get it to throw an error which is why you see the error as you do. | The plugin generated 80 characters of unexpected output! | wordpress |

Is there a way to add a custom field value (if it exists) to the permalink? | Here's how I'd do it. I'm just going to say, I haven't tested this code at all, so I don't know if it even works. It's more of a starting point for you. <code> function jpb_custom_meta_permalink( $link, $post ){ $post_meta = get_post_meta( $post->ID, '<insert your meta key here>', true ); if( empty( $post_meta ) || !is_string( $post_meta ) ) $post_meta = '<insert your default value (could be an empty string) here>'; $link = str_replace( '!!custom_field_placeholder!!', $post_meta, $link ); return $link; } add_filter( 'post_link', 'jpb_custom_meta_permalink', 10, 2 ); </code> You would also have to go to your permalinks and change them to include <code> '!!custom_field_placeholder!!' </code> , like so: <code> '/%year%/%monthnum%/!!custom_field_placeholder!!/%postname%/' </code> This will not add any significance to your permalinks, merely text. If you need to add meaning to the text that goes there, that's a lot more work. | Custom field values in permalink | wordpress |
I would like to add a "Click to download" button to one of my WordPress plugins, and I'm not sure which hook to use. So far, hooking 'admin_init' to this code seems to work: <code> header("Content-type: application/x-msdownload"); header("Content-Disposition: attachment; filename=data.csv"); header("Pragma: no-cache"); header("Expires: 0"); echo 'data'; exit(); </code> This seems to work, but I just want to see if there is a best practice out there. Thanks, Dave | Hi @Dave Morris : If I understand you correctly you want to have a URL something like the following whose response to the browser will be the content you generate, i.e. your <code> .CSV </code> file and no generated content from WordPress? <code> http://example.com/download/data.csv </code> I think you are looking for the <code> 'template_redirect' </code> hook. You can find <code> 'template_redirect' </code> in <code> /wp-includes/template-loader.php </code> which is a file all WordPress developers should become familiar with; it's short and sweet and routes every non-admin page load so be sure to take a look at it. Just add the following to your theme's <code> functions.php </code> file or in another file that you <code> include </code> in <code> functions.php </code> : <code> add_action('template_redirect','yoursite_template_redirect'); function yoursite_template_redirect() { if ($_SERVER['REQUEST_URI']=='/downloads/data.csv') { header("Content-type: application/x-msdownload",true,200); header("Content-Disposition: attachment; filename=data.csv"); header("Pragma: no-cache"); header("Expires: 0"); echo 'data'; exit(); } } </code> Note the test for the <code> '/downloads/data.csv' </code> URL by inspecting <code> $_SERVER['REQUEST_URI'] </code> . Also note the added <code> ,true,200 </code> to your <code> header() </code> call where you set the <code> Content-type </code> ; this is because WordPress will have set the <code> 404 </code> "Not Found" status code because it doesn't recognize the URL. It's no problem though as the <code> true </code> tells <code> header() </code> to replace the <code> 404 </code> WordPress had set and to use the HTTP <code> 200 </code> "Okay" status code instead. And here's what it looks like in FireFox ( Note the screenshot doesn't have a <code> /downloads/ </code> virtual directory because after taking and annotating the screenshot it just seemed like a good idea to add a <code> '/downloads/' </code> virtual directory): UPDATE If you want the download to be handled from a URL that is prefixed with <code> /wp-admin/ </code> to give the user the visual indication that it is protected by a login you can do that as well; the description of one way follows. I encapsulated into a class this time, called <code> DownloadCSV </code> , and to created a user "capability" called <code> 'download_csv' </code> for the <code> 'administrator' </code> role (read about Roles and Capabilities here ) You could just piggyback off of the predefined <code> 'export' </code> role if you like and if so just search & replace <code> 'download_csv' </code> with <code> 'export' </code> and remove the <code> register_activation_hook() </code> call and the <code> activate() </code> function. By the way, the need for a activation hook is one reason why I moved this to a plugin instead of keeping in the theme's <code> functions.php </code> file.* I also added a "Download CSV" menu option off the "Tools" menu using <code> add_submenu_page() </code> and linked it to the <code> 'download_csv' </code> capability. Lastly I chose the <code> 'plugins_loaded' </code> hook because it was the earliest appropriate hook I could use. You could use <code> 'admin_init' </code> but that hook is run much later (1130th hook call vs. the 3rd hook call) so why let WordPress do more throw-away work than it needs to? (I used my stackexchange-url ("Instrument Hooks plugin") to figure out which hook to use.) In the hook I check to ensure my URL starts with <code> /wp-admin/tools.php </code> by inspecting the <code> $pagenow </code> variable, I verify that <code> current_user_can('download_csv') </code> and if that passes then I test <code> $_GET['download'] </code> to see if it contains <code> data.csv </code> ; if yes we run practically the same code as before. I also remove the <code> ,true,200 </code> from the call to <code> header() </code> in the previous example because here WordPress knows it is a good URL so didn't set the 404 status yet. So here is your code: <code> <?php /* Plugin Name: Download CSV Author: Mike Schinkel Author URI: http://mikeschinkel.com */ if (!class_exists('DownloadCSV')) { class DownloadCSV { static function on_load() { add_action('plugins_loaded',array(__CLASS__,'plugins_loaded')); add_action('admin_menu',array(__CLASS__,'admin_menu')); register_activation_hook(__FILE__,array(__CLASS__,'activate')); } static function activate() { $role = get_role('administrator'); $role->add_cap('download_csv'); } static function admin_menu() { add_submenu_page('tools.php', // Parent Menu 'Download CSV', // Page Title 'Download CSV', // Menu Option Label 'download_csv', // Capability 'tools.php?download=data.csv');// Option URL relative to /wp-admin/ } static function plugins_loaded() { global $pagenow; if ($pagenow=='tools.php' && current_user_can('download_csv') && isset($_GET['download']) && $_GET['download']=='data.csv') { header("Content-type: application/x-msdownload"); header("Content-Disposition: attachment; filename=data.csv"); header("Pragma: no-cache"); header("Expires: 0"); echo 'data'; exit(); } } } DownloadCSV::on_load(); } </code> And here's a screenshot of the activated plugin: And finally here's a screenshot of triggering the download: | How can I force a file download in the WordPress backend? | wordpress |

Cheers! | Okay, thanks to all who contributed to answering my question, but I had finally figured out the solution to my problem. Sorry for being naive but it turned out that I had a template_redirect action added to direct anything that's related to my post types to their respective template files .

I want this question to turn into a more of a wiki because people often have this question. What do you think are some useful and must-have plugins for a wordpress-based site? Currently, I'm in the early stages of setting up a blog and I'm looking around for great plugins and some good tips. Please do include one or more. Also, if it's already there, upvote it. | These are all plugins that I've used, and while I'm sure there's a lot of good plugins I've missed, but these are ones I've had experience with and would recommend as enhancing your WordPress blog. Akismet - this is included with WordPress and is (in my opinion) one of the essential plugins you will need once you start to receive pretty much any traffic - the bots won't be far behind. While it's not perfect, it goes a reasonably good way towards expunging the spam. All in One SEO - Does what it says on the tin. Some of the <code> <meta> </code> tags generated are ignored by many search engines now but most of the options inside of here will benefit you in some way or another. Contact Form 7 - Makes it really easy to add a contact form to your site, with the field that you want, not necessarily the 'standard' ones. For more advanced needs, it's possible to configure multiple forms. Offers easy integration with reCAPTCHA and Akismet. FD Feedburner - Feedburner is a really great tool for gauging statistics related to your feeds. This plugin handles the redirection of your feeds to Feedburner, and requires next-to-no configuration. Google Analyticator - This plugin makes it easy to add Google Analytics tracking to your blog, and includes dashboard integration. Also supports link tracking, so you can see the direction in which people left your blog. Google XML Sitemaps - Generates an XML sitemap of your sites contents. It's possibly one of the best ways to ensure that Google (+ others) indexes all of your sites content. Sitemaps are automatically built when changes are made, and search engines are pinged, which notifies them of the changes. It also has a pretty comprehensive set of options, meaning you can change almost everything about the generated sitemap. W3 Total Cache - W3TC is an awesome plugin for helping WordPress scale. It packs some pretty impressive features, including the redirection of your resources to a CDN (along with syncing the two) and the static-caching of your posts. | What are good plugins for beginners? | wordpress |

What I am trying to do is create a custom post type, custom meta box that inserts the values of it into an array of 'colors' or, 'p_clrs'. I have a jQuery script which works, allowing you to click a link to "Add Another Color", which adds another input field below the one which shows always by default (must show at least 1 colors metabox). The jQuery added input fields should store the values of each one that gets added, as another 'color' in the array of 'colors' which I'm trying to create. When on the newpost page or edit page for existing posts, the colors metabox needs to run a foreach loop to create a metabox foreach 'color' that exists in the 'p_clrs' variable. I am not good at all with arrays, and multi-arrays, and especially foreach loops. I hate foreach loops lol. I've gotten it all so close to working, I don't want to do it all over using taxonomies, and once I get this to foreach loop over each color of the array which I am trying to create here, I will be able to handle anything else I need to with this stuff. I just can't get over the array/foreach hump I'm stuck on here. This is my Product Class for my custom post type. This is what I have all the values for the posts info (including my other metaboxes which the codes aren't included here for them). <code> class TypeProducts { public $prod_meta_fields = array( 'title', 'description', 'product_type', 'post_tag', 'p_sku', 'p_price', 'p_discnt_price', 'p_weight', 'p_size_w', 'p_size_h', 'p_clrs' ); </code> Here is the method which also has my register_post_type() and register_taxonomy() codes but that isn't really needed for this so I left it out. After the register_ptype and _tax() functions are called, I add the actions for things that need to be added to the init and stuffs. <code> public function TypeProducts() { add_action( 'admin_init', array( &$this, 'product_meta_boxes' )); add_action( 'wp_insert_post', array( &$this, 'wp_insert_post' ), 10, 2 ); } </code> This method is what does all the inserting of information for each of the post form fields. It works for all my custom metaboxes too, *Except for the additional input fields that jQuery adds when you click the "Add Another Color" link/button. <code> public function wp_insert_post($post_id, $post = null) { if ($post->post_type == 'product') { // my custom post type is 'product' foreach ($this->prod_meta_fields as $key) { // loops over the $prod_meta_fields $value = @$_POST[$key]; if (empty($value)) { delete_post_meta($post_id, $key); continue; } if (!is_array($value)) { if (!update_post_meta($post_id, $key, $value)) { add_post_meta($post_id, $key, $value); } } else { delete_post_meta($post_id, $key); foreach ($value as $entry) add_post_meta($post_id, $key, $entry); } } } } </code> Here's the method for adding my metabox(es). Not sure whether I could/should do the foreach within this, looping over the array of $p_clrs values to add a metabox foreach color that exists, if there are more than one. Otherwise, there should just be one metabox displayed (at all times there should be at least 1). <code> function product_meta_boxes() { add_meta_box( 'products-price', 'Product SKU# &amp; Price', array( &$this, 'prod_price_box' ), 'product', 'side', 'high' ); add_meta_box( 'products-colors', 'Product Colors', array( &$this, 'prod_colors_box' ), 'product', 'normal', 'high' ); } </code> Here's my method for outputting the metabox(es) itself, and also the jQuery script that adds and removes additional input fields which "could" potentially become metaboxes upon saving the post if the added boxes arent empty. Here's a picture of what I mean to give you an idea of what I'm talking about. Currently the first input shows on page load with any value which is stored if any. When clicking the Add Another link, it adds another input with the same value, but when saving a different value in any input field, it saves the value of the last input that has a value. And only shows one input upon reloading the page when you save it too. I need to show inputs for each added value that was there, which needs to also be inserted to the 'p_clrs' variable/array in order to do that foreach 'p_clrs' value that exists. Lost yet? <code> public function prod_colors_box() { global $post, $p_clr; $p_clr = array(); $p_clrs = get_post_meta( $post->ID, 'p_clr', true ); ?> <div id="p_colors"> <p> <label for="p_clr_1"> <strong>Color:</strong> <input id="p_clr_1" name="p_clr" value="<?php echo $p_clrs; ?>" /> </label> </p> </div> <h4><a href="#" id="addClr">Add Another Color</a></h4> <script src="http://code.jquery.com/jquery-1.4.3.min.js"></script> <script type="text/javascript"> $(function() { var clrDiv = $('#p_colors'); var j = $('#p_colors p').size() + 1; $('#addClr').live('click', function() { $('<p><label for="p_clr_' + j + '"><strong>Color:</strong> <input id="p_clr_' + j + '" name="p_clr" size="20" value="<?php echo $p_clrs; ?>" /></label> <a href="#" id="remClr">Remove</a></p>').appendTo(clrDiv); j++; return false; }); $('#remClr').live('click', function() { if( j > 2 ) { $(this).parents('p').remove(); j--; } return false; }); }); </script> <?php } </code> <code> } // end of TypeProducts{} Class </code> Thanks for any help anyone can give me, and sorry if this is a little crazy of a post.

I am using WordPress mu 2.9.2 and have the same category structure on all my blogs. How do I add categories to all my blogs simultaneously? Is there a plugin that does this effectively? | You could write a script for that, here is something I wrote in Perl lately: first the sql statements to check if the term already exist and if not insert it: the prepared statements: <code> my $wts = $dbh->prepare( "SELECT term_id FROM $tb_wp_terms WHERE name = ?") or die "Couldn't prepare statement: " . dbh->errstr; my $wti = $dbh->prepare( "INSERT INTO $tb_wp_terms (name, slug) VALUES (?,?)") or die "Couldn't prepare statement: " . dbh->errstr; </code> then make the term taxonomy entry: the prepared statements: <code> my $wtts = $dbh->prepare( "SELECT term_taxonomy_id FROM $tb_wp_term_taxonomy WHERE term_id = ? AND taxonomy = '".$config{'wordpress.taxonomy_type'}."'") or die "Couldn't prepare statement: " . dbh->errstr; my $wtti = $dbh->prepare( "INSERT INTO $tb_wp_term_taxonomy (term_id, taxonomy, count) VALUES (?,?,1)") or die "Couldn't prepare statement: " . dbh->errstr; my $wtts_count = $dbh->prepare( "SELECT count FROM $tb_wp_term_taxonomy WHERE term_taxonomy_id = ? AND taxonomy = '".$config{'wordpress.taxonomy_type'}."'") or die "Couldn't prepare statement: " . dbh->errstr; my $wtti_count = $dbh->prepare( "UPDATE $tb_wp_term_taxonomy SET count = ? WHERE term_taxonomy_id = ? ") or die "Couldn't prepare statement: " . dbh->errstr; </code> And use the queries above with some code around it (you need to check for blogs that already have some of the categories). For MU only the blogs > 1 get a blog id in their table name: <code> my $tb_blogid = ""; if ( $config{'wordpress.wp_mu_blog_id'} > 1 ) { $tb_blogid = "_" . $config{'wordpress.wp_mu_blog_id'}; } my $tb_posts = $config{'wordpress.prefix'} . $tb_blogid .

FeedWordPress is pulling in two, three, four, and as many as 15 copies of the same post when it updates (via manual cron triggers or via auto updates). It doesn't happen all the time, and it doesn't happen with every post. I also noticed that it occasionally says that a FWP post was "created locally on this site", even though it wasn't. Copies of that same post will sometimes say "local", and sometimes "syndicated". And one more strange behavior, it's actually posting stuff from one domain into another completely different domain, but it only seems to pull the post_title across, no content or categories. I'm on a WP Multi-site 3.0.1 install with FWP v2010.0905. I'm also using WP Super Cache if that might make a difference. Has anyone experienced any of this before? Does the duplicated posts FWP filter work properly? Thanks for your help, Dave Morris | You can use the "syndicated_post" hook that's available in FWP and hook in a function that checks for duplicate posts. <code> add_action('syndicated_post', 'fwp_check_duplicate'); </code> I started working on this a few months back but did not complete it. I basically got to the point of flagging potential duplicates and putting them in draft mode instead of publishing. <code> function fwp_check_duplicate ( $post ) { global $wpdb; $handle; $possible_duplicate; $query = "SELECT id,guid FROM $wpdb->posts WHERE post_title = '%s' AND post_date_gmt like %s"; $sql = $wpdb->prepare( $query, $post['post_title'], gmdate('Y-m-d', $post['epoch']['issued'])."%" ); $results = $wpdb->get_results( $sql, ARRAY_N); foreach ( $results as $result ) { if ( $result['guid'] != $post['guid'] ) { $possible_duplicate = true; } } if ($possible_duplicate) { $post['post_status'] = "draft"; } // Otherwise continue to process. return $post; } </code> Hope that helps. | FeedWordPress duplicated posts problem | wordpress |
I have read the discussion on the performance of different permalinks on the wp hackers mailinglist, THIS forum and around Google. I could however not really deduce if the permalink structure I have been using for the past years is good or not: <code> /%postname%-%year%%monthnum%%day%.html </code> This combination put the postname directly after the / and the year,month,day combination makes it more unique since many postnames carry the same name. The html addition is something I have been using for the past 10 years on my blog (even pre wordpress) so that is legacy. I dont know if this is good for permance or bad for performance, how can i check this?
