Description

This filter hook allows you to change the meta data of post, page or any other post type.

If you want to remove any from default or add new meta field, this hook will allow you to change the meta fields.

For example, if you have added new post meta named ‘total_views’ and you want to add log of this field, then this filter will be used.

Usage

add_filter( 'ualp_post_meta_array', 'my_post_meta_array' );
function my_post_meta_array( $get_default_metakey_array ) {
    // remove thumbnail id from log
    if (($key = array_search('_thumbnail_id', $get_default_metakey_array)) !== false) {
        unset($get_default_metakey_array[$key]);
    }
    
    // add total_views post meta in log
    $get_default_metakey_array[] = 'total_views'; //total_views is meta_key
    //
    //return array
    return $get_default_metakey_array;
}
