This filter hook allows you to display serialized category or term ids array field in string with its title.

For example, you have added new post meta named ‘related_cat_ids’ by using filter ‘ualp_post_meta_array’. related_cat_ids field contains array of category ids. WordPress will store array in serialized format. When you want to display serialized category ids array field in valid format, this filter hook will be very useful.



add_filter( 'ualp_post_meta_array', 'my_post_meta_array' );

function my_post_meta_array( $get_default_metakey_array ) {
    // add connected_post_ids post meta in log
    $get_default_metakey_array[] = 'related_cat_ids';
    //return array
    return $get_default_metakey_array;

add_filter( 'ualp_cat_serialized_array', 'my_cat_serialized_array' );

function my_cat_serialized_array( $serialized_array ) {
    // display total_emails post meta in proper format
    $serialized_array[] = 'related_cat_ids';
    //return array
    return $serialized_array;
