Hi,
I’m using post type metabox with ‘clone’ and ‘sort’ option.
I haven’t selected any posts, but rgm_meta has zeros in the array.Get filed Value:
$posts_related = rwmb_meta( 'post_related', array(), $id ); var_dump($posts_related); array(1) { [0]=> int(0) }
I want the array to be empty if nothing is selected.
Field settings:
array ( 'id' => 'post_related', 'type' => 'post', 'name' => 'title', 'post_type' => array( 0 => 'post-type-1', 1 => 'post-type-2', 2 => 'post-type-3', ), 'field_type' => 'select_advanced', 'clone' => 1, 'sort_clone' => 1, ),
*I can select multiple in Select Advanced, but I can’t change the order, so I use a ‘clone’.
Regards,
