Reply To: Hierarchical Custom Posts using Relationship custom field

Hey

Thanks for the reply.

That helps a little. I now have this filter in place, which as you say, orders the posts by menu_order.

// filter for every field
add_filter('acf/fields/relationship/query', 'my_relationship_query', 10, 3);
function acf_relationship_query( $args, $field, $post )
{
    $args['orderby'] = 'menu_order'; 
    return $args;
}

But, this takes the menu_order as is. By this I mean, you would have a root level post with a menu_order of 1. But you also have a child of a root level post also with a menu_order of 1. This means that the posts aren’t in a hierarchical order still.

Using my example in the first post, you would now have:

1/ Electrical Items
1.1/Drills
3.1/ Bricks
1.2/Mowers
2/ Timber
3.2/ Plumbimg
3/ Building Materials

Really what I need to be able to do is create a recursive function that orders the posts under a specific post, and return them in an ordered array?
