Hi @wootimes
Please keep in mind that you don’t need to pass the post ID to the get_sub_field()
function. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/get_sub_field/.
So you should do it like this:
function ACF_GSF( $field, $post_id = null ) {
if ( ! is_acf() ) { return false; }
if ( get_sub_field( $field ) ) {
return get_sub_field( $field );
} else {
return false;
}
}
I hope this helps 🙂
