The get_pages function is rather old and really shouldn’t be used anymore. Use a get_posts instead (a Page is just a special type of Post): $listingPages = get_posts( array( ‘meta_key’ => ‘streetAdd’, ‘post_type’ => ‘page’, ‘post_status’ => ‘publish’, ‘orderby’ => ‘meta_value’, ‘order’ => ‘ASC’, ) );

To pass data from js back to PHP simplest way is use json_encode or, in WP, its wrappers wp_send_json, wp_send_json_error and wp_send_json_success. Usage example: On PHP side function get_latest_product_meta() { $post_id = (int) filter_input(INPUT_GET, ‘post_id’, FILTER_SANITIZE_NUMBER_INT); $post_id or wp_send_json_error(); // array_shift because when used like so `get_post_meta` return array of arrays… $data = array_map(‘array_shift’, get_post_meta($post_id)); … Read more
Example code in add_meta_box() documentation uses save_post hook (at the very end of wp_insert_post() function) to add custom fields data from metabox. You must be using something like that already in your metaboxes, is it not appropriate place to validate your data?..

Unfortunately not. The only way is to deregister the metabox, and then re-register it, supplying your own callback function which mimics the original metabox, but with your alterations (making sure the names of the inputs do not change). This method is outlined in these posts: custom post type taxonomies UI radiobuttons not checkboxes Custom-Taxonomy as … Read more
