Unfortunately you cannot perform a meta_query using a LIKE comparison on the meta_key value when using WP_Query. I’ve been down this road… Instead you have a couple other options if you want to maintain like status relationships as post meta and not user meta and or meta in a custom table.

$post in the callback function is an array, not an object. So you cannot use $post->id. Change it to $post[‘id’] and it should work: function slug_get_phone_number($post, $field_name, $request) { return get_post_meta($post[‘id’], ‘_phone’, true); } I recommend to change _phone to phone_number or something else without underscore prefix. Because _ is often used with private meta … Read more
This would need a query. So building on your code: <?php $postTitle = $_POST[‘post_title’]; $submit = $_POST[‘submit’]; if(isset($submit)){ global $user_ID, $wpdb; $query = $wpdb->prepare( ‘SELECT ID FROM ‘ . $wpdb->posts . ‘ WHERE post_title = %s AND post_type = \’stuff\”, $postTitle ); $wpdb->query( $query ); if ( $wpdb->num_rows ) { $post_id = $wpdb->get_var( $query ); … Read more

get_the_ID() can (only) be used within the loop. This retrieves the ID of the current post handled by the loop. You can use it on it’s own if you need it only once: $dish_meta = get_post_meta( get_the_ID(), ‘dish_meta’, true ); You can also store it as a variable if you need it more than once: … Read more
