MySQL query to set wp_postmeta using term_taxonomy_id value
I think I know what you mean, and if that is the case it’s actually a straightforward operation. Firstly get all the object_ids from the term_relationship table. $results = $wpdb->get_results(“SELECT `object_id` FROM $wpdb->term_relationships WHERE `term_taxonomy_id` = 18”); And then run through each of those values and update_post_meta to 18. foreach ( $results as $result ) … Read more
Alternative to simple fields plugin?
While you can create this all from scratch in your theme, I have really been liking the plugin Advanced Custom Fields as an alternative. It has a few flaws, but the major ones (such as slowing down your site) seem to have been fixed, and it’s super-easy to use. Best of luck to you!
making sense of admin-ajax
The function that returns the contents of that ajax request will not be in admin-ajax.php. That is the core WordPress file that handles ajax requests, but it is not used for specifying the data returned by ajax functions in themes / plugins. In the theme (somewhere), will be a line that looks like this: add_action(‘wp_ajax_myajax-submit’, … Read more
Per site configuration
You should make a plugin, that way it is portable to any theme. Generally speaking people need to stop filling up functions.php or theme files with code that is better suited for scalability and flexibility, aka a plugin.

Calling custom profile fields?
Try instead $user_contactmethods[‘work’] = __(‘I work for…’); and <?php echo get_user_meta($current_user->ID,’work’,true);?> where the array index is ‘work’ instead of ‘I work for…’, i.e. lowercase and without any spaces.
nextgen gallery: how to get picture url by gallery id
After analyzing nextgen core files I have found solution to my problem. I hope it will be useful for somebody. global $nggdb; $get_gall_id = get_post_meta($post_id, ‘galerijos_id’, true); $gall_ids = $nggdb->get_ids_from_gallery($get_gall_id); $images = $nggdb->get_gallery($get_gall_id); foreach ( $gall_ids as $gall_id ) { echo $images[$gall_id]->imageURL .'<br>’; }
Separate table or usermeta
The obvious advantage of user meta is that you can use the WordPress API to record and retrieve these extra columns, without writing extra PHP classes or SQL queries. The wp_usermeta table is pretty well indexed, in fact, it uses one row per field (rather than one column if you use a custom table), and … Read more
How to get the db table row that has the biggest value in the meta value?
The WP_Query has a feature called meta_query. Using it allows you to either query by value or numeric value: $car = new WP_Query( array( ‘post_type’ => array( ‘cars’ ), ‘meta_key’ => ‘car_number’, ‘orderby’ => ‘meta_value_num’, ‘posts_per_page’ => 1, ‘order’ => ‘DESC’, ‘cache_results’ => true, ) ); $carNr = get_post_meta( $car->ID, ‘car_number’, true ); // Inspect … Read more
