You can create groups of meta_queries using specific compare operation on them, and since you want to order based in a single custom field, you can keep the order declaration dedicated to the single meta field. So: $q = new WP_Query( array( ‘meta_key’ => ‘population’, //setting the meta_key which will be used to order ‘orderby’ … Read more
Short version: _encloseme is added to a post when it’s published. The wp-cron process should get scheduled shortly thereafter to process the post to look for enclosures. In other words, it cleans them up normally later. Nothing to worry about. Full explanation: “Enclosures” are links in a post to something like an audio or video … Read more
If all of your custom post type posts have all meta fields that you need then you can use the fields argument and set it to ids which will work much faster for example: //get your custom posts ids as an array $posts = get_posts(array( ‘post_type’ => ‘your_post_type’, ‘post_status’ => ‘publish’, ‘posts_per_page’ => -1, ‘fields’ … Read more
It looks like the nightly builds of the Advanced Custom Fields plugin can (mostly) handle this now, so you could try installing that. Details on this support issue. I can’t update my copy of it to test right now but this is what it would look like in the admin:
My first answer was completely off-mark and I’m completely rewriting it… But thanks to Milo’s hint, I found the solution here: http://wordpress.mcdspot.com/2011/05/24/search-admin-user-list-on-first-and-last-names/ After adapting it, this works for me with ‘facebook’ and ‘twitter’ author_meta. add_action(‘pre_user_query’,’wpse_27518_pre_user_query’); function wpse_27518_pre_user_query($user_search) { global $wpdb,$current_screen; if ( ‘users’ != $current_screen->id ) return; $vars = $user_search->query_vars; if(‘facebook’ == $vars[‘orderby’]) { $user_search->query_from … Read more
If we define the conditions: A: my_custom_field_ignore EXISTS B: my_custom_field_ignore = 1 then NOT ( A && B ) is equivalent to: NOT ( A ) || NOT ( B ) meaning in our case: ( my_custom_field_ignore NOT EXISTS ) || ( my_custom_field_ignore != 1 ) We could therefore try the following for WP 3.5+ … Read more
I’m sorry, but for now there is no easy way to “enable” revisioning of postmeta. However, you can add post metadata to revisions. A guy named John Blackburn wrote a pretty good article about adding post metadata to revisions. You find it here: https://johnblackbourn.com/post-meta-revisions-wordpress
You’re on the right track. I test the fields in the save_post callback, and then use admin notices to display errors to the user when a field fails validation. They show up just in a highlighted box at the top of the page, just like any errors/messages that WordPress itself generates. Here’s a simple example … Read more
The get_field_object ACF function can be used to get info and options for a specific field. First you need the field key of the specific field you wish to output. When editing a field group, click on the screen options tab at the top of the page. You should see an option to toggle the … Read more
To query posts by custom fields you can use the ‘meta_query’ parameter <?php $args = array( ‘post_type’ => ‘payment’, ‘meta_query’ => array( array( ‘key’ => ‘bookingref’, ‘value’ => ‘the_value_you_want’, ‘compare’ => ‘LIKE’ ), array( ‘key’ => ‘customerref’, ‘value’ => ‘the_value_you_want’, ‘compare’ => ‘LIKE’ ) ); query_posts($args); while (have_posts()) : the_post(); ?> you can’t use get_post_meta … Read more
