Hi @darusharp

When passing an empty array to ‘include’, all results are returned…
.. which I guess is what you are saying 🙂

I tested the above scenario, and when no posts are chosen, $ids is in fact empty…

You can test if it *has* any values by doing:

if ($ids) {
  $args = array(
    'numberposts' => -1,
    'post_type' => 'daylily', //my custom post type
    'include' => $ids,
    'orderby' => 'title',
    'order' => 'ASC',
  );
  $wishlistitems = get_posts($args);
} else {
  echo 'No one is wishing for anything at the moment';
}

Hope that helps!
