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.

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.
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.

You can use the admin_enqueue_scripts hook for add custom javascript files into the backend.
see documentation for get_field. change: $attachment_id = get_field(‘image’); to pass the post ID as second argument: $attachment_id = get_field(‘image’, 299); or: $attachment_id = get_field(‘image’, $my_id);
Doesn’t look like the return value of `get_post_custom_values()’ is well defined in the codex. My guess is that as long as you have a costume field called ‘_url’ set in any of your posts the result will be an empty array, and only if you don’t have it in any post it will return null. … Read more
You can easily do this using Custom RSS Feed method very well explained by Joost ( For reference: http://yoast.com/custom-rss-feeds-wordpress/ ). Using this way, you can display any of the fields either custom field value or featured image.
<?php $querystr = “SELECT {$wpdb->posts}.ID, {$wpdb->posts}.post_title, {$wpdb->prefix}stt2_meta.meta_count FROM {$wpdb->posts}, {$wpdb->prefix}stt2_meta WHERE {$wpdb->posts}.post_type=”post” AND {$wpdb->posts}.post_status=”publish” AND {$wpdb->posts}.ID IN ( SELECT post_id FROM {$wpdb->prefix}stt2_meta ) ORDER BY {$wpdb->prefix}stt2_meta.meta_count DESC LIMIT 10;”; $pageposts = $wpdb->get_results($querystr, OBJECT); ?>
