Hello James and thanks for giving a hand!
I find interesting this “update_value” filter but I think that the “save_post” is more suitable to my needs, as long I can put all fields logic in only one function.
How can I access a specific field old and new posted value in acf/save_post action???
Maybe:
function my_acf_save_post( $post_id ) {
// specific new field value
$new_value = $_POST['acf']['field_abc123'];
// specific old field value
$old_value = get_field('custom_field_name', $post_id);
}
// run before ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 1);
PS: Also can I use get_fields() instead get_field() in order to get all fields old values??
Regards!
