title: Theme customizer: How do you grab the value later?

text: I'm working on a custom site, doing all my work in a child theme. I need to add one variable, slider speed, to the customize control system. I've been able to modify the custom controls via the following additions to my child- theme functions.php file:               function Primm_customize_register( $wp_customize ) {          $wp_customize->add_section( 'primm_section' , array(         'title'     => __( 'Primm Home Page', 'Divi-child' ),         'capability' => 'edit_theme_options',         'description' => 'Setting options for home page'     ) );          $wp_customize->add_setting(        // ID        'primm_slider_speed',        // Arguments array        array(            'default' => '5000',            'type' => 'option'        )     );     $wp_customize->add_control(         // ID         'primm_slider_speed',         // Arguments array         array(             'label' => __( 'Cycle Time on Slider (0.001 secs)', 'Divi-child' ),             'section' => 'primm_section',             'type' => 'text',             // This last one must match setting ID from above             'settings' => 'primm_slider_speed'         )     );     }      add_action( 'customize_register', 'Primm_customize_register' );      That stuff seems to work well. I can make changes on the admin custom menu, save the settings and see that a value seems 'set'. On the other hand, I'm attempting to call that variable from within my home.php file.                $slider_timing= get_theme_mod('primm_slider_speed');      echo("Slider Timing: ".$slider_timing);  // test only      var_dump($slider_timing);      total fail. This is my response:                Slider Timing: bool(false)                   Been working on this for hours. I'm missing something, but its just not clear to me what. Note: my child theme is "Divi-child" (based on the directory name at root/wp-content/themes/Divi-child ) Anybody been here before on the general topic of Wordpress Theme customizer? How do I allow admin users to set a value in 'storage' and then retrieve it again later? Many thanx, Zip.


title: Widget only in first post

text: I want to put a widget area into the content of the first post. My problem though is that is can't figure out how to get only the first post in my function. Here is my function:                   function pietergoosen_insert_content_filter( $content ) {         ob_start();         $sidebar = dynamic_sidebar('sidebar-19');         $new_content = ob_get_clean();         if ( ! is_admin() ) {             return pietergoosen_insert_content( $new_content, 2, $content );         }         return $content;     }      If i replace               if ( ! is_admin() ) {      with               if ( ! is_admin() || is_paged() || $wp_query->current_post > 0 ) {      it shows the widget in all other posts and not in the first post. Any suggestions on a conditional tag for this


title: Is it possible to visually group items on the theme customizer?

text: My theme customizer is getting bigger and I think from an UX perspective would be nice to visually group some similar items. Is there way to do that? Something like put a divider or playing with CSS among the items or even put them into 'parent' sections.


title: How can I lock down an old wordpress install I don't intend to update?

text: I am starting a new wordpress blog, and no longer updating an old one. The old one still gets 400-500 hits a day, so I would like to keep it up for archival purposes, as people still link to its posts. Obviously there is the problem that wordpress and plugins will be updated, and I have no desire to maintain it. How can I lock the installation of wordpress down so I don't need to maintain it? I have seen someone suggest making a static version, which sounds like alot of work. A more reasonable solution I thought of was to disable write access to the database at the database user level. I'm fine with disabling comments from now on. Feel free to share any thoughts or comments on this. Thanks in advance.


title: What filters to call to modify the output of the entire page?

text: I want to write a simple plugin. For every time a page is viewed, it will write to the MySQL database. Then, if the current hour is odd, it will set a PHP variable of $is_odd to true;               <?php       require_once('library-of-functions-to-support-this-plugin.php');       function_to_write_to_mysql_db();       $is_odd = false;       if(current_hour_odd()) {         $is_odd=true;       }       $is_odd_json = json_encode($is_odd);     ?>      Then, it should embed the following JavaScript (note: I've already modified the theme's templates to put an on each page):               <script type="text/javascript" src="jquery.js"></script>     <script type="text/javascript">        var odd = <?php echo $is_odd_json; ?>;        if(odd) {           $("#OddElement").html('Odd!');        }     </script>      So basically, I have no idea where to put these code snippets. What filters do I want to apply? I know this plugin seems stupid, but it's laying the groundwork for something else I want to do. Thanks so much!


title: Best and Cleanest way to remove /category/ from category permalinks?

text: > **Possible Duplicate:**   >  Remove parent category from permalink? Basically only have the child > category?

We really would like to achieve this the cleanest and simplest way possible, without worrying about out-dated plugins or causing problems with too many mods.


title: change set_post_thumbnail_size according to post type admin page

text: I have a few custom thumbnail sizes and obviously one of them is used in the set_post_thumbnail_size, what directly affects the interface in the admin area. What I'm looking to do is to intercept which admin page (for post-type) I'm in and set a different size in the above function, so basically I'd like to have that:               function setup_the_theme() {              add_theme_support( 'post-thumbnails' );                  if ($post_type == 'type_A'){                 set_post_thumbnail_size( 298, 167, true ); //portrait             } else {                 set_post_thumbnail_size( 192, 108, true ); //landscape             }              add_image_size( 'top_articles', 298, 167, true ); //portrait         add_image_size( 'article_thumb', 203, 114, true ); //portrait         add_image_size( 'featured_articles', 60, 200, true ); //landscape          }     add_action( 'after_setup_theme', 'setup_the_theme' );      I suspect its too early in the cycle to know which post type i'm editing.


title: WooCommerce - How to Add a Custom Field to Cart Items and Cart Totals

text: I am using WooCommerce plugin and have the following query: Within the single product page, I have a product where based on certain selections by the buyer, a shipping cost value is calculated, which I then need to pass/include as part of the cart items as a new column, "Shipping Cost" when viewing your cart. The thing is though, the buyer might decide to buy say three different products where each of these three products might have varied shipping cost calculations, after pressing the "Add to Cart" button three times. For example:               Product A selections calculates a Shipping Cost of $2.00     Product B selections calculates a Shipping Cost of $4.00     Product C selections calculates a Shipping Cost of $6.00      So based on the above, when the buyer has finished shopping and presses "View Cart", I want them to see:               Item                       Price      Shipping Cost      Quantity          Total          ---------------------------------------------------------------------------------------     Product A                      $10        $2                     1                 $10     Product B                      $5         $4                     1                 $5     Product C                      $15        $6                     1                 $15      It is the "Shipping Cost" custom field column I would like to add to the cart, which is what I am unsure how to do. Further to the above, I also want to add to the "Cart Totals" below, another custom field of "Shipping Cost" which would total $12, which would then beed added to overall Product Total, i.e.               Cart Totals          Cart Subtotal       $30     Shipping Cost       $12          Order Total         $42      Some of the code that I have used for the Cart Total shipping cost is:               function woo_add_cart_fee() {       global $woocommerce;       $woocommerce->cart->add_fee( __('Shipping Cost', 'woocommerce'), 100 );     }     add_action( 'woocommerce_before_calculate_totals', 'woo_add_cart_fee');      So, I need to know how to add the "Shipping Cost" to both the Cart Product Details as well as to the Cart Totals. Any coding help would be much appreciated. Thanks.


title: How do I restart my loop with get_next_post()?

title: Get a count of how many times a term or a category is used in posts

text: I need to find out the number of times a term/tag or category is used in a post in WordPress. I wrote the below SQL query.

Please advice where I might be going wrong?


title: wp_get_referer not working properly after wp_redirect

text: Thank you for reading! There's a lot redirecting going on on the site I'm creating. For example,   * if not logged in user access a "private" page, he will be redirected to a custom login page.   * if the user logs in, he will be redirected to the last page he visited before accessing the login form. Let's call the pages "Profile" and "LogIn". So, if everything goes well should be: > -> not logged try to access **Profile** -> redirect to **LogIn** -> if OK > redirect to **Profile** However, when **LogIn** calls wp_get_referer(), it does NOT return **Profile**. Instead it goes "2 pages" back. Is like "wp_get_referer()" is not seing **Profile** as the referer because is acting as a redirection. Just like the "Back" button in the browser would. **If you go to the LogIn through any 'public' page (clicking the link) the redirect after login in works fine.** **page-profile.php**               if( !is_user_logged_in() ) {             wp_redirect( get_permalink(37) ); //id 37 = page-login.php         exit;     }      **page-login.php**               //Set referer     $referer = wp_get_referer();     if( !$referer || referer_is_login_page($referer) )         $referer = get_bloginfo('url');     simpleSessionSet('login_referer', $referer);          ...      //Log the user in      ...          if ( is_wp_error($user_id) )                     $errores = TRUE;     else          wp_redirect( simpleSessionGet('login_referer', '') );


title: Best hook for a function which adds shortcodes to the system?

text: I have a plugin released, and one of my customers was reporting a problem where the plugin was outputting ads in the header area of their website. I have a function defined which contains my shortcode definitions, for example, the function contains a few of these `add_shortcode( 'myshortcode', 'my_function' ); ` I am executing the function via the following command `add_action( 'init', 'add_my_shortcodes');` Doing it thisway causes a conflich with my plugin (which outputs adsense ads) and the google analytics in the header). I was testing different hook positions for my add_action, and it appears that `add_action( 'loop_start', 'add_my_shortcodes');` If my plugin is for outputting of ads, what is the best place to hook? I need it to be available anywhere in the template, or content. For example, they can put it in posts, sidebar widgets, or straight hard coded into the theme via a `do_shortcode` in their template files. In order to ensure my shortcode is registered before any content is generated, but AFTER their header scripts, I moved my way down this list http://codex.wordpress.org/Plugin_API/Action_Reference until the ads worked properly. I ended up landing on the hook `loop_start` which doesn't sound like an ideal place to hook into. Can anyone suggest the best hook location so that it is executed before any output, but after the opening `<body>` tag? I'm assuming I need to get as close to the `<body>` tag as possible, but I could be wrong.

I want to use the the PressThis bookmarklet to save items to a category called "readlater". I would like that it always posts to this category and that I never have to select a category before posting. It's ok if the category box is removed or replaced with something else as I won't ever need to use it. Could someone show me what to modify to make this happen? Here is the section within press-this.php that pertains to categories:                   <?php $tax = get_taxonomy( 'category' ); ?>
         <div class="handlediv" title="<?php esc_attr_e( 'Click to toggle' ); ?>">

Here's a great answer by Otto, unfortunately it doesn't work for me (I'm trying to make it work in single-customposttype.php, it displays nothing, replacing `$post->ID` with `$page->ID` or `$parent->ID` displays EVERYTHING from Media Library ). # UPDATE Looks like I don't understand something right. I took a snippet I've seen around in many places, also in Otto's post above:               $gallery_images = new WP_Query(array(             'post_parent' => $post->ID,             'post_type' => 'attachment',             'post_mime_type' => 'image',             'post_status' => 'inherit',     ));          while ( $gallery_images->have_posts() ) : $gallery_images->the_post();             the_title();              the_content();              the_permalink();     endwhile;      I pasted it into content.php of Twenty Thirteen and guess what? It returns NOTHING, and of course this post HAS gallery and get_post_gallery_images($post) work on it flawlessly. What am I doing wrong? Of course when I UPLOAD image to the gallery code above works, because the image is uploaded / attached directly to this post. All of my other images are of course "(Unattached)" and this might be a problem... # UPDATE II Got it, finally. Looks like Gallery images used to be attached to posts in WP pre-3.5, now it doesn't work this way. Here's it well explained. So the question is - is this solution good and is it safe to use it for the future? Of maybe it's possible to play with get_post_gallery_images sizes? To be honest this function would be so much more powerful if it would load all image sizes in multidimensional array...

I get re-directed to the login page again.   * domain.com/wp-admin I can log in if I use the following urls.   * domain.com/wp-admin/ (with the forward slash on the end)   * domain.com/admin   * domain.com/login I pointed the domain I want to use to the installation of my wordpress, which is under a sub-directory of the root.   * Disabled permalinks (removed web.config which is I guess .htaccess for windows)   * Disabled plug-ins   * Verified Site URL in the database (It doesn't contain an extra forward slash) When I log into wp-admin I am redirected to. domain.com/wp-login.php?redirect_to=http%3A%2F%2Fdomain.com%2F **sub- directory** %2Fwp-admin%2F&reauth=1 The url is incorrect and the sub-directory should not be there. Visiting wp-admin/ with the forward slash directs me to the correct url. domain.com/wp-login.php?redirect_to=http%3A%2F%2Fdomain.com%2Fwp- admin%2F&reauth=1 GoDaddy Support does not see an issue here.


title: orderby:date not working

text: I have been searching for an answer and it seems like there are a lot of answers for the opposite issue. I am trying to sort by publish date, not by date modified, using this code:               query_posts($query_string . '&orderby=date&order=DESC&posts_per_page=-1');      But it is still sorting on date modified not publish date, can anyone help? Thanks in advance!


title: Each custom image size in custom upload directory?

text: I want to upload my custom image sizes in custom folders. The folder should have the name of the selected width. For example: If I add these custom sizes...               add_image_size('custom-1', 300, 9999);     add_image_size('custom-2', 400, 9999);      It would be nice the uploaded images are uploaded like this:               http://www.my-site.com/wp-content/uploads/300/my-image.jpg     http://www.my-site.com/wp-content/uploads/400/my-image.jpg      Is this possible? I've only found that I can change the global upload folder with the upload_dir filter.


title: Why is a wordpress login session limited to one domain

text: I have a wordpress installation on my virtual host, where the document root is accessible as both "somesite.com" as well as "www.somesite.com". If I set up site_url as "http://somesite.com", then when I access "www.somesite.com" then wordpress thinks I am not logged in (and I can't see private posts and such), while if I set site_url to "http://www.somesite.com", then the same problem happens with "somesite.com". I would really like both variations to be acceptable.

title: What is better to use, user meta, custom taxonomies or new database structure?

text: I am looking for some advice. I will be working on user follow system (like twitter) for my site. I expect it to have a large number of users using this system. So, I would like to know what is better to use to store all the data for this system. Should I use user meta, custom taxonomies or should I work directly with the database? I was thinking about creating some user meta, so each user has meta for followers and a meta for following, each would be filled with users' ids. Is there a better way from the stanpoint of scalability? Thanks!


title: Does WordPress require that your submitted theme supports multiple menu levels?

title: Is it possible to orderby multiple meta_keys when using meta_value_num?

text: Reading through the order & orderby documentation, it's not clear to me whether there is any support to order based on multiple `meta_key` values. Obviously, using `meta_query` I can return posts based on multiple key-value pairs, but I want to be able to control the order that these results are returned based on multiple `meta_keys`. For example, I have pages that have multiple categories and each category has a numerical rank. If a user is searching for pages that are in one of three different categories, I can return all the necessary posts with the following:               $query = array(       'order' => 'DESC',       'orderby' => 'meta_value_num',       'meta_query' => array(         'relation' => 'OR',         array( 'key' => 'cat1', 'type' => 'numeric' ),         array( 'key' => 'cat2', 'type' => 'numeric' ),         array( 'key' => 'cat3', 'type' => 'numeric' )       );     );      However, once those are returned, I would like them to be ordered based on the highest numerical value across any one of the categories that results were returned on. In other words, posts with a `9` value in `cat1` would appear around the same order as posts with a `9` value in `cat3`. Looking at this answer it seems that a `meta_key` isn't even necessary for `'orderby' => 'meta_value_num'`, but that doesn't match the documentation for `meta_value`, which is far more documented than `meta_value_num`... Any clarification would be useful. Thanks!


title: get comments by current user inside page template

text:
I want to add a page template inside my custom post type and retrieve inside that page the comments posted by current user. I have this code for getting the current user:                         <?php          global $current_user;     get_currentuserinfo();          echo 'Username: ' . $current_user->user_login . '

';     echo 'User display name: ' . $current_user->display_name . '
';     echo 'User ID: ' . $current_user->ID;     ?>      The code for getting the comments of the current user:                    <?php      $args = array(     'user_id' => 1, // use user_id         'post_type' => 'my-CPT',      );     $comments = get_comments($args);     foreach($comments as $comment) :         echo($comment->comment_author . '

                 <?php                     wp_list_comments( array( 'callback' => 'outbox_comment' ) );                 ?>
      And this is how my **page-commentsbyuser.php** is looking:               <?php          /**      * The template for displaying a list of comment from the current user      *      */          get_header();              ?>

      This is not working and also I don't know how can I get the comments of the current user. Any suggestions on how I can retrieve the comments from the CPT of the current user inside this page template ?

title: Converting a theme to a child theme in a network

text: I'm converting a few themes to children of another theme. I want the themes to have the same name as before, and I'd like the change to be transparent to the users of my blog network. When I replace the themes' folders with child themes in the wp-content/themes directory, the blogs in my network do not work properly until I:   1. Access wp-admin/themes.php for each, which automatically disables the new child theme (it says that it has an error or is invalid) and sets the theme to the network default.   2. Manually reactivate the child theme. My blog network is pretty large. Is there a way to automate whatever is happening above so that I don't have to do it manually for every blog in the network?

title: Custom columns for multiple custom post types

text: I currently have 2 issues with Custom Post Types... First of all I'm trying to setup custom columns in Admin to display and act correctly. I have a Custom Post Type called 'acme_products' and a Taxonomy called 'product_type'. I have followed the Yoast tutorial http://yoast.com/custom-post-type-snippets/ (amongst others!) which has almost got me there... The problem is under the column 'Product type' instead of displaying the 'product_type' Taxonomy it simply says 'Array', and links to localhost:8888/wp-admin/Array. I don't actually mind if it doesn't link anywhere, so long as the Taxonomy displays correctly. Code is below plus an explanation of what I changed:               // Add columns to the overview page for a Custom Post Type          function change_columns( $cols ) {         $cols = array(             'cb'       => '<input type="checkbox" />',             'title' => __( 'Product', 'trans' ),             'product_type' => __( 'Product Type', 'trans' ),             'date'     => __( 'Date', 'trans' ),         );         return $cols;     }     add_filter( "manage_acme_products_posts_columns", "change_columns" );               // Give these new columns some content          // Below I changed 'get_post_meta' to 'get_the_terms'     // This was taken from a further tutorial to target taxonomies rather than post_meta          function custom_columns( $column, $post_id ) {         switch ( $column ) {             case "product_type":                 $product_type = get_the_terms( $post_id, 'product_type', true);                 echo '' . $product_type. '';                 break;         }     }     add_action( "manage_posts_custom_column", "custom_columns", 10, 2 );               // Make these new columns sortable          function sortable_columns() {         return array(             'title' => __( 'title' ),             'product_type' => __( 'product_type' ),             'date'     => __( 'date' ),         );     }     add_filter( "manage_edit-acme_products_sortable_columns", "sortable_columns" );      Further to this problem, I have a second Custom Post Type called 'acme_courses' with a Taxonomy of 'course_locations'. How would I go about applying the custom columns to a second (and potentially 3rd & 4th) Custom Post Type? If I duplicate the code above, and change bits to reflect the new Custom Post Type and Taxonomy, it breaks everything! I get a white screen both in admin and on the site. Thanks in advance!!!

title: Practical Solutions to HTML5 Video on WordPress

text: I was directed here from Stack Overflow -- We work with clients who have WordPress sites and one thing we keep struggling with is implementing HTML5 video across all browsers and devices in the WordPress environment. We've tried multiple plugins (JW Player, MediaElement, Sublime Video). It seems like each one has its own bugs, and are difficult to implement video play-lists on (Not to mention having a good UI for the client to manage/add videos themselves). What is a solid, reliable solution to HTML5 video on WordPress? Something that can support up to 4 file types at once (.mp4, .webm, ogg, flash) and possible have a playlist functionality. Should I ditch the plugin solution entirely and write the code myself?

title: PHP displaying wrong custom taxonomy images

text:
I'm using the Taxonomy Images plugin to try to pull in the category images for custom categories on a page that displays all the categories my site has. For some reason, this code outputs the correct names and descriptions, but will only show one category image. I'd like the images to do what the other category features do, populate with the appropriate data for each category and display all the categories on the page. If I use `echo wp_get_attachment_image( $imgs[$id], 'thumbnail' );` it publishes all of the images, but if I change that from `echo` to make it a variable, it only displays one image.               $imgs = get_option( 'taxonomy_image_plugin' );     $categories = get_terms('portfolio_category', array('orderby' => 'id', 'hide_empty' => 0));     foreach ( $categories as $category ) {         $id = $category->term_id;         $img = wp_get_attachment_image( $imgs[$id], 'thumbnail' );     }         for($i=0; $i<count($categories); $i++)          {          echo('
'.$categories[$i]->name.'
');          echo($img);          echo('

');     }      I guess that I'm just confused as how to add a counter like `[$i]` so that this code outputs the correct category images. Any help would be much appreciated.

I am familiar with this feature at the wordpress level but I am unable to locate where bbpress registers a large number of these callbacks. Specifically I would like to change the behaviour of the callback which is triggered via:               do_action( 'bbp_template_before_forums_loop' );      If someone could help me locate this callback so that I can change the HTML it outputs that would be greatly appreciated.


title: Orderby custom date fields with meta_query broken on OR relation

text: I have an 'event' post type that has custom start and end date fields. In a block on the home page, I'm trying to show only upcoming or ongoing events. So, to achieve this, I'm doing a meta_query that compares the two date fields to today's date with the intent of showing events with start or end date equal to today's date or later. After getting the returned events, I'm sorting by the start date. One important note, some events have end dates, while some are merely one day events with just a start date.               <?php /* Start the loop */     $args = array(         'post_status' => 'publish',         'post_type' => 'event',         'posts_per_page' => 5,         'meta_key' => '_venh_start_date',         'orderby' => 'meta_value',         'order' => 'ASC',         'meta_query' => array(             'relation' => 'OR',             array(                 'key' => '_venh_start_date',                 'value' => date('Y-m-d'),                 'compare' => '>=',                 'type' => 'DATE'             ),             array(                 'key' => '_venh_end_date',                 'value' => date('Y-m-d'),                 'compare' => '>=',                 'type' => 'DATE'             ),         )     );     $my_query = new WP_Query( $args ); ?>     <?php while ( $my_query->have_posts() ) : $my_query->the_post(); ?>      The query works but the 'orderby' is broken. If I take the second meta_query (end date) out of the equation and remove the 'OR' relation, the sort works perfectly. So the orderby statement is clearly failing when the second meta_query is added. Does anyone have any ideas what I might be doing wrong? Any help is greatly appreciated! @s_ha_dum, the generated SQL is as follows: `string(640) "SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts INNER JOIN wp_postmeta ON wp_posts.ID = wp_postmeta.post_id INNER JOIN wp_postmeta AS mt1 ON (wp_posts.ID = mt1.post_id) INNER JOIN wp_postmeta AS mt2 ON (wp_posts.ID = mt2.post_id) WHERE 1=1 AND wp_posts.post_type = 'event' AND (wp_posts.post_status = 'publish') AND (wp_postmeta.meta_key = 'x_start_date' OR (mt1.meta_key = 'x_start_date' AND CAST(mt1.meta_value AS DATE) >= '2014-02-24') OR (mt2.meta_key = 'x_end_date' AND CAST(mt2.meta_value AS DATE) >= '2014-02-24') ) GROUP BY wp_posts.ID ORDER BY wp_postmeta.meta_value ASC LIMIT 0, 5"`

title: How to create access to a wordpress site via registration/login page?

text: What I want is, whenever a visitor tries to access my wordpress site, either by putting in the url or by clicking on a link from external source, he/she has to go via the registration/login page (if not already logged in). Which means, the visitor has to be a member of the site to get access to it. Once the registration is complete, the registrant would be redirected to the login page, and once he logs in, he would be redirected to the page he wanted to visit. How do I do it? Please help.

title: Temporary Infinite Redirect Loop

text: I have written a custom WordPress plugin for a certain site (this is not a public plugin, it is private written for that specific site). The plugin reads RSS entries from other sites, and then for each RSS entry, it goes to the specific url in the RSS entry, and donwloads more information from that page. This process runs on request. Meaning, there is a 'run' button, and when this button is clicked, the process above starts; and it stops when all the RSS entries are read. Everything works just fine. But sometimes during the run of the process described above, I get an infinite redirect loop error. I am not sure what is causing it. The error stays for about half an hour or an hour. What happens is whenever I go to my site site (while the process is running and when the error happened), I get the message: This webpage has a redirect loop. I cannot go to any webpage on the site, nor I can login to the admin area. I noticed one weird thing as well. My WordPress site is setup in a subdirectory. In other words, if my domain was **www.example.com** , my WordPress files are located at **www.example.com/subfolder** as a security measure. But when I try to go to **www.example.com** and when the redirect error happened, the URL changes to **www.example.com/wp-admin/install.php** (it is even bypassing the subfolder setup, it should have been pointing to **www.example.com/subfolder/wp-admin/install.php** instead). This whole thing clears automatically about half an hour or one hour later and the site would work normally! Now, I do not like this. I do not want this to even happen in the first place. Do you have an idea of why is this happeneing? And do you have an idea on how to fix this? Thanks a lot.

title: Add custom fields when specific templates are selected

text: I'm trying to make change to a site where with the current infrastructure isn't great as due to how it's been built over the previous site rather then fresh. I have a section of the site which needs it's own custom fields. This section doesn't warrant it's own post type, and due to the state of the site it's extremely impractical to do it this way. What I don't want for the sake of the user is to have to make them use the custom fields as it's pretty sloppy. So, how can I add fields (like you would for a custom post type) when a certain template is selected?

title: Best way to initiate a class in a WP plugin?

text: I've created a plugin, and of course being me, I wanted to go with a nice OO approach. Now what I've been doing is to create this class and then just below create an instance of this class:               class ClassName {              public function __construct(){              }     }          $class_instance = new ClassName();        I'm assuming there is a more WP way to have this class initiated, and then I came across people saying that they prefer to have an `init()` function than a `__construct()` one. And similarly I found the a few people using following hook:               class ClassName {              public function init(){              }     }     add_action( 'load-plugins.php', array( 'ClassName', 'init' ) );      What is generally considered the best way to create a WP class instance on load and have this as a globally accessibly variable? **NOTE:** As an interesting side point, I've noticed that while `register_activation_hook()` can be called from within the `__construct`, it cannot be called from within the `init()` using the second example. Perhaps someone could enlighten me on this point. **Edit:** Thanks for all the answers, there clearly is a fair bit of debate as to how handle the initialization within the class itself, but I think there's generally a pretty good consensus that `add_action( 'plugins_loaded', ...);` is the best way to actually kick it off... **Edit:** Just to confuse matters, I've also seen this used (although I wouldn't use this method myself because turning a nicely OO class into a function seems to defeat the point of it):               // Start up this plugin     add_action( 'init', 'ClassName' );     function ClassName() {         global $class_name;         $class_name = new ClassName();     }


title: How to stop wp_postmeta from being called on archive and search pages?

text: Currently, when I load a search or result page, it queries the `wp_postmeta` table which is leading to the page taking ages to load. I realise this is a result of this table being huge (70k rows), and because of how much data is loaded into the cache. Is there a way to stop `update_post_caches` from being called when these pages are loaded, and then send custom (and more efficient) queries to the database once the template has been loaded? ![enter image description here](http://i.stack.imgur.com/1f1oU.png)

title: What are the benefit in adding hook in the init() hook?

If I have a back up of the `functions.php` file, can I just replace the screwed up file via FTP or do I have to do something else? The same questions goes for `.htaccess` file - if I add this code:               php_flag register_globals off      to it, can I change something irreversibly or do I just upload the back up and all goes back to normal?


title: WP appending -2 to the end of my slug. Where are the originals stored so I can delete them?

text: I've been learning about taxonomies, custom posts etc though a lot of trial and error. I finally have it working how I want, however now I am getting some conflict with my desired slugs. I can't name my category "venue" because someplace in the database, that's already taken (I assume) - even though I've deleted the category that used it. Now when I try adding the category that I want to use the "venue" slug, WP automatically makes it "venue-2", which I definitely don't want in my url as the folder. Any suggestions for this?

title: API JSON Data in WordPress

text: On the _Google developer API_ page, it talks briefly on retrieving a dynamic list of fonts using JSON/JavaScript. I was wondering how would I be able to pull the web fonts API into my Wordpress theme so that I'm not creating my own list or have to constantly release an update of fonts. Thank you.


title: How to auto-approve internal pingbacks?

text: Whenever I write a post on my blog and link to a previous post, that pingback shows up as a comment needing to be approved. I am running Disqus, but this was happening even pre-use of that plugin. ![comment settings](http://i.stack.imgur.com/x9UdB.png) What is the fix for this behavior?


title: How to show last comment on hover?

text: WordPress usually has "Leave a Comment, "1 Comment," or "% Comments" on the blog page, and I want people to be able to hover over that and have jQuery show the latest comment in a rectangular box below it (pushing down all subsequent content). Obviously they'd click through to read more comments or respond, but I can't figure out where to start and go from there. As an example, if you look at the site Destructoid, they show the latest comment after each post. I want to show something similar, but only after the "# comments" is hovered over. Only then would the box with the latest comment show up and push the rest of the content down. It would disappear if the mouse is moved off of the link or box itself. I figure get_comments can be used to call it, but comments_popup_link doesn't take arguments for alt text or jQuery boxes, I don't think. Any suggestions?


title: Not Found (404) error on admin page, CSS gone on blog

text: I manually installed wordpress on my server and the wordpress files are located in "www.mydomain.com/wordpress/", however I wanted my "www.mydomain.com" to be the address for my wordpress blog instead of "www.mydomain.com/wordpress/" so I went to the "Settings->General" screen in my dashboard and changed the "Home" url to "www.mydomain.com/wordpress" and the "Site" url to "www.mydomain.com" thinking it would make my home address the blog address. When I went back to the admin page I get a "Not Found (404)" error message and all the CSS formatting is gone from my blog. Is there a way to reset my settings?

title: is_front_page, is_page('slug'), is_page(id) not working

text: None of the following are working to display conditional format in the sidebar when the current page is the home page:   * is_front_page,   * is_page('home'),    * is_page(id) I added an else clause which is implemented on the home page. In Options > Reading, I have specified a page called Home to be the front page. The slug 'home' and the page id of 13 (obtained from the URL when editing the Home page) all return false. If I place `<?php the_ID(); ?>` in the sidebar, it displays the post ids of blog posts which are also displayed (title only) by home.php (which is the template assigned to the home page). I don't know how else to explicitly display the page id on the front end so I know I'm using the correct id.


title: How much string content can I store in an option?

text: I am about to create a new plugin that fetches remote content and stores it locally for use on the WP website. I have a free plugin that does this with twitter and tweets, and I store a JSON file in the plugin directory. Some users complain that the plugin cannot write files to the folder due to permissions. For this reason, I have been thinking about storing the remote content for this new plugin in an option. Is 250kb of HTML too big for an option? Is there another API call that can help me store a large chunk of string data?

title: ABSPATH in Windows

text: I'm having a a pain in the head using the `ABSPATH` constant in Windows.   Addressing files and folders in Windows is usually done using the `\` (forward-slash) character while for Linux the character would be `/` (backslash).   Unfortunately the `ABSPATH` in Wordpress is defined with only Linux in mind (putting a `/` at the end of it).   I wonder if I can over-ride it's definition since in `wp-config.php` it's defined under an `if` clause which indicates it can be defined elsewhere. **Problem detalis:**   1. I'm running on `localhost`   2. The problem is with the `statpress-visitors` internal addressing. This is how it addresses the files:               ABSPATH . 'wp-content/plugins/' . dirname(plugin_basename(__FILE__)) . '/def/os.dat'      And this is what I get as output:               C:\wamp\www\wp/wp-content/plugins/statpress-visitors/def/os.dat

However, I don't know which part of coding is used to verify the password as I want to refer to the existing coding. Could you help me?

title: How can I autopopulate titles in the media library?

text: I have hundreds of images in my media library, most have which have no titles. In the media library, the "(no title)" message is displayed along these images. Since I generally have one image per post, I would like to auto-populate the library titles, by grabbing the associated post name. I don't mind if I overwrite some existing titles. Does anyone know of a hack that will do this? I found some plugins, like 'Media Rename' and 'Rename Media' and 'SEO friendly images' but they are usually for renaming the actual image files, or for creating HTML title tags directly in the HTML (on the fly). I want to create titles within the Wordpress media library, so that I don't see the (no title) message. This title data will also help me to search for images in the library -- although, for anyone with the same issue, I did find a plugin called 'Media Search' that enables searching images by associated posts: http://wordpress.org/extend/plugins/media-library-search/


title: Assign CPT archive page attributes

text: I have a custom post type `recipes` which uses the `archive-recipes.php` template automatically. I have a Wordpress page called `Top Recipes` which is set to use the `archive- recipes.php` template in the CMS. When browsing to `www.mysite.com/top-recipes/` I get the **Top Recipes** title displayed along with the **Featured Image** I set in the CMS followed by the list of recipes. But the problem occurs when browsing to `www.mysite.com/recipes/` The title and featured image are that of the latest recipe to be entered into the database. How can I assign the `/recipes` custom post type archive to have the same title/ featured image as the `Top Recipes` page?


title: W3 Total Cache Minify Rewrite Error with Wordpress on nginx

WP_Filesystem();     global $wp_filesystem;          $mySettingsFileLocation = WP_PLUGIN_DIR.'/my-settings/settings.ini';          if ( ! $wp_filesystem->put_contents( $mySettingsFileLocation, $mySettings, 0644) ) {         return true;     }               // Define the path to file      $file = WP_PLUGIN_DIR.'/my-settings/settings.ini';           if(!$file)      {              // File doesn't exist, output error              die('file not found');      }      else      {      // Set headers      header("Cache-Control: public");      header("Content-Description: File Transfer");      header("Content-Disposition: attachment; filename=settings.ini");      header("Content-Type: application/ini");      header("Content-Transfer-Encoding: binary");           // Read the file from disk      readfile($file);      }


title: How does Wordpress redirect to WooCommerce shop page?

text: I'm creating a plugin for WooCommerce, it needs a parameter in the url of shop page like this `http://domain/wp/shop/?param=value`. It worked fine until I set the shop page as front page, when I access `http://domain/wp`, it is showing the shop page, but when I access it with the parameter (`http://domain/wp/?param=value`), it's showing the blog index page. So, I want to ask where exactly in the Wordpress code that redirects the url to WooCommerce shop page? so I may be able to change the redirection behaviour or something else.


title: Loop output for custom plugin [solution found]

text: I am trying to update my plugins to be more user-friendly. One of the things i want to achieve is that i want my plugins output (e.g. for description-fields) to use the full functionality of all normal wordpress posts and pages (use TinyMCE and Loop-Output). I've found a great article on using the tinyMCE right here but what I'm still stuck at is the usage of loop formatting by other plugins. Given Example: I use a download manager plugin. In custom posts and pages i can write `[download id=1]` and it get's nicely formatted by the asociated plugin. I want this functionality in my custom plugins, too. Right now this is the way i do my plugin output:               add_filter('the_content', array(&$myclass, 'myclass_callback'), 7);      and myclass_callback is the following:               public function myclass_callback($sIn)     {       if (isset($_GET['myc_id']) && is_numeric($_GET['myc_id'])) {         $sOut = $this->myclass_detail((int)$_GET['myc_id']);         return str_replace('[[MYCLASS_TAG]]', $sOut, $sIn);       }       $sOut = $this->myclass_index();       return str_replace('[[MYCLASS_TAG]]', $sOut, $sIn);     }      And this approach doesn't bring my wanted result :) So i am trying to figure out how to, but apparently I'm not good enoug of a googler to do so :S Any links or keywords for me to search for will be greatly appreciated. Thanks in advance!


title: Display trimmed version of the_post()

text: I am using the following code to display pages on one page and would like to trim the content of each page on this display to 50 words and include images that are attached to the page. How do I go about doing this?                 $args = array(                 'post_type' => 'page',                 'post_parent' => '6',                 'order'=> 'DESC'                      );                 query_posts($args);                 while ( have_posts() ) : the_post();

title: Vimeo Feed gived dead link with RSS widget?

text: I have RSS widget on my home page (footer) pointing to a RSS feed from Vimeo. The videos pull in fine, and the links for these work. The orange RSS icon also takes you to the actual RSS feed. However, the title takes you to a 404. I am not sure if this is a fault of how Vimeo is setup, or the widget. Can anyone think of a workaround to ensure this title is not a dead link? This short screencast explains the situation.


title: How to insert pictures without hard coded dimensions?

text: How can I insert pictures into a post without any hard coded dimensions (e.g. `<img src="" alt="" />` instead of `<img src="" alt="" width="" height="" />`)? I don't want my users to switch to the HTML tab and remove the parameters by themselves, so I was wondering if there is any filter I can use to achieve this? Note: I'm already inserting them in "Full size".
