Individual Widgets per Page
You can do it using Widget Context plugin or Widget Logic plugin. They work fine. I prefer Widget Context because it has more flexibility.

ORDER BY custom field value
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: $q = new WP_Query( array( ‘meta_key’ => ‘population’, //setting the meta_key which will be used to order ‘orderby’ … Read more
The “_encloseme” Meta-Key Conundrum
Short version: _encloseme is added to a post when it’s published. The wp-cron process should get scheduled shortly thereafter to process the post to look for enclosures. In other words, it cleans them up normally later. Nothing to worry about. Full explanation: “Enclosures” are links in a post to something like an audio or video … Read more
Any way to add custom options to Gallery Settings?
It looks like the nightly builds of the Advanced Custom Fields plugin can (mostly) handle this now, so you could try installing that. Details on this support issue. I can’t update my copy of it to test right now but this is what it would look like in the admin:
Sortable Custom Columns in User Panel (users.php)?
My first answer was completely off-mark and I’m completely rewriting it… But thanks to Milo’s hint, I found the solution here: http://wordpress.mcdspot.com/2011/05/24/search-admin-user-list-on-first-and-last-names/ After adapting it, this works for me with ‘facebook’ and ‘twitter’ author_meta. add_action(‘pre_user_query’,’wpse_27518_pre_user_query’); function wpse_27518_pre_user_query($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
How to enable revisions for post meta data?
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
Query Posts or Get Posts by custom fields, possible?
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
What is “meta_input” parameter in wp_insert_post() used for?
This part of wp_insert_posts() gives it away: if ( ! empty( $postarr[‘meta_input’] ) ) { foreach ( $postarr[‘meta_input’] as $field => $value ) { update_post_meta( $post_ID, $field, $value ); } } where we see how the post meta fields are updated/added with update_post_meta(). Here’s the inline description for meta_input: Array of post meta values keyed … Read more
What is the index [0] for on post meta fields?
Each post meta key can have multiple values. So you get the values by default as an array; the first entry (0) is the oldest. get_post_custom() fetches all meta keys with their values. You could simplify your code with: $price = get_post_meta( $post->ID, ‘price’, TRUE ); $comake = get_post_meta( $post->ID, ‘coMake’, TRUE ); When the … Read more
Underscores in custom fields
Custom field names are arbitrary. The underscore hides it from the Custom Fields metabox on the post editing page. When referencing these custom fields in meta_query() or other functions, the underscore has to be used. Source: conversation with @toscho, @rarst and @wyck in the chat room.
