Hi There

I am switching back to the Relationship field as it seems to sort of handle the cat filter.

Here is my code

function my_relationship_query( $args, $field, $post )
{
    // increase the posts per page
    //$args['cat'] = wp_get_post_categories($post->ID);
	$args['cat'] = '3,5';
	
    return $args;
}
 
// filter for a specific field based on it's key
add_filter('acf/fields/relationship/query/key=field_524f02159316d', 'my_relationship_query', 10, 4);

using 3,5 works, but wp_get_post_categories($post->ID) does not work, just displays the loading icon.

Also – Is it possible to limit the number of items that can be added from left to right to only 1?
