This will show the checkboxes that have been ticked (much simpler!!): <?php $categories = get_field(‘categories’); $elements = array(); foreach($categories as $category) { //do something $elements[] = ‘<a href=”https://wordpress.stackexchange.com/tags/design/” . strtolower($category) . ‘” title=”‘ . $category . ‘”>’ . $category .'</a>’; } echo implode(‘,’, $elements); ?>
You can store an array in a custom field; WordPress serializes it for you on save and unserializes it on get. Name your fields with a pseudo array syntax: <input name=”mycustomfield”> <input name=”mycustomfield[date]”> You’ll get a $_POST array: mycustomfield = array ( ‘audio’ => ‘somevalue’, ‘date’ => ‘somedate’ ) Now you can do whatever you … Read more

The latest version of WPML (version 2.3) has a new module for Media and this module takes care of the previous images issue. Now there is no longer the need to upload the same image twice. Just like copying the content from the original language, it is now also possible to duplicate the images and/or … Read more
Not knowing your specific setup makes this pretty tricky … but here are some ideas for alternatives that might save you time: Leave it as-is If these authors aren’t actually users of the site to begin with, don’t change anything. Non-users shouldn’t be turned into users just for the sake of making search easier. Creating … Read more

This can easily be done with default PHP functions. // Loop through all fields, grab the content and assign it to a new array foreach ( get_post_custom() as $custom ) $new_custom[] = array_shift( $custom ); // Get rid of empty fields $new_custom = array_filter( $new_custom );
the_terms() echoes output. To assign output to a variable and check if there is any you need to use get_the_term_list() instead. Note that it might also return WP_Error object (which won’t be empty) so you will need to check for it as well with is_wp_error().
Try changing your display_url_info function to <?php add_filter(‘beernews-child-theme_post’, ‘display_url_info’); function display_url_info() { // usually needed global $basic_metabox; $basic = $basic_metabox->the_meta(); if($basic[‘post_link_url’]) { echo $basic[‘post_link_url’]; } else { echo ‘ERROR : “post_link_url” empty’; } } ?> And not to be a jerk, but I would like to point out that WP Alchemy is not a plugin … Read more
You can do it with a posts_where filter and a subquery. Note that you have to explicitly set suppress_filters to false, as get_posts normally ignores filters: function wpse28018_posts_where( $where ) { global $wpdb; $where .= ” AND {$wpdb->posts}.ID NOT IN ( SELECT DISTINCT post_id FROM {$wpdb->postmeta} WHERE meta_key = ‘alternate_page’ )”; return $where; } // … Read more
