Hi @soroka
I believe you can use the acf/fields/page_link/result/ filter hook. This hook is not documented yet, but you can use it like this:
add_filter('acf/fields/page_link/result/name=show_link', 'my_acf_modify_page_link_title', 20, 4);
function my_acf_modify_page_link_title( $title, $post, $field, $post_id ){
// get the series title
$series_title = get_field('series_title', $post->ID);
// only set the title if it's found
if($series_title) $title = 'Series Title: ' . $series_title;
// return the title
return $title;
}
Please keep in mind that this will only work for ACF PRO version.
I hope this helps 🙂
