Post Object Query Filter Issue

Hi guys. I have the following function that I am hooking into a post object field (query) To filter posts user specifically:

add_filter('acf/fields/post_object/query/name=which_event_is_this_document_for', 'my_post_object_query_for_specific_user', 10, 3);

function my_post_object_query_for_specific_user( $args, $field, $post )
{

    global $current_user, $wp_roles; get_currentuserinfo();

    $user_id = $current_user->ID;

    $events = get_field('events', 'user_'.$user_id ) ? get_field('events', 'user_'.$user_id ) : false;

        $event_info = array();

        if($events){

            foreach( $events as $event){

                $event_info[] = $event->ID;
                
            }

            $args['include'] = $event_info;

        }
          
        $args['orderby'] = 'meta_value';

        $args['meta_key'] = 'date';

    return $args;
}

This works absolutely fine. However, If I introduce a something into the query argument that causes no results;

for example

$args['post_parent'] = 9999999; //Testing Purposes

I get a ‘Loading Failed’ error. I had a look at the select2.js code and it looks like it should be returning ‘No matches’. (Bug?)

I would ideally like to hook into this message and display ‘You have no events’.

Is there a way to do this?

Hi @magicstick,

Thanks for the post.

I would recommend you make use of the acf/validate_field filter to attach some custom validation to the field and return a custom error message.

I hope this helps.
