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_post_ids’ by using filter ‘ualp_post_meta_array’. Plugin will display the lable as ‘Related post ids’. If you want to change the label, 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 ) { $get_default_metakey_array[] = 'related_post_ids'; //return array return $get_default_metakey_array; } add_filter( 'ualp_replace_key', 'my_cat_serialized_array' ); function my_cat_serialized_array( $label ) { if($label == 'Related post ids') $label = 'Related Posts'; //return label return $label; }
