You should use dynamic_sidebar()s for that. You can read more about it in Code. They allow you to use widgets, like – for example – a custom menu widget. More about the custom menus inside wp-nav-menu.
There are a couple filters for that. I wrote a tutorial about adding custom columns, which is where the code below is from. The example is adding a column to the ‘page’ post type that displays the page’s template. You can hook into load-edit.php and use get_current_screen to grab the correct screen ID’s/filters. From there … Read more
To delete a file from the file system, you can use something like this attached to an AJAX hook that is called by jQuery: function ajax_remove_image() { check_ajax_referer( ‘image_removal’, ‘image_removal_nonce’ ); if ( ! $_POST[ ‘confirm’ ] ) exit( ‘false’ ); $uploads = wp_upload_dir(); $upload_dir = $uploads[ ‘path’ ]; $file = strpos( $_POST[ ‘file’ ], … Read more
You’re speaking about custom field content and not meta box content – the meta box is the wrapper box where custom fields are displayed. For the custom field display, you can create a WP_Query with a meta condition, i.e. adding a specific condition whether a custom field is set and with a specific value. @Rarst … Read more
Let MySQL do the job: global $wpdb; $metakey = ‘YOUR_METAKEY_GOES_HERE’; $results = $wpdb->get_results( $wpdb->prepare( “SELECT meta_value, COUNT(*) AS counter from {$wpdb->postmeta} WHERE meta_key = %s GROUP BY meta_value ORDER BY counter DESC”, $metakey, ARRAY_N ) ); ); $resuls is an array with the ordered results.
Ok I found a solution for my scenario. I combined those two plugins to filter by custom taxonomy and custom field: Query Multiple Taxnomies http://wordpress.org/extend/plugins/query-multiple-taxonomies/ Custom Query Fields http://wordpress.org/extend/plugins/custom-query-fields/ I changed the QMT Plugin template by adding the possibility to choose several custom fields and do a combined query. The URL now looks as follows: … Read more
Assuming that your site front page is displaying a static page, the reason that your meta data doesn’t appear on the site front page is because you only enable your post custom meta box for post post-types: $meta_box = array( // … // refer to this array key ‘page’ => ‘post’, // … ); // … Read more
To list the options for a custom taxonomy you need to query the taxonomy terms. To do that you use get_terms() http://codex.wordpress.org/Function_Reference/get_terms // We are assuming color is the name of the taxonomy $colors = get_terms( ‘color’, array( ‘orderby’ => ‘name’, ‘hide_empty’ => 0 )); // Now loop through the colors and spit out the … Read more
Based on your comments above, you are just passing a wrong id or you need to modify delete_pdf_and_metadata function. intval(‘aps_pdf1’) is 0, and that’s why your response is 0!
This will fire on init so you just need to refresh a page one time for it to work. I left out the actual value of $new_value — you need to define that. <?php add_action( ‘init’, ‘wpse_75308_update_video_meta’ ); function wpse_75308_update_video_meta() { // Get all posts $posts = get_posts( array( ‘numberposts’ => -1 ); // Loop … Read more
