Hi @inforesist
In that case, I believe you can do it like this:
function my_relationship_query( $args, $field, $post_id ) {
// only show children of the current post being edited
$args['orderby'] = 'date';
$args['order'] = 'DESC';
// return
return $args;
}
// filter for a specific field based on it's name
add_filter('acf/fields/relationship/query/name=relationship_custom_field_name', 'my_relationship_query', 10, 3);
Where “relationship_custom_field_name” is the name of your custom field. To learn more about the arguments, please take a look at this page: https://codex.wordpress.org/Class_Reference/WP_Query.
Hope this helps.
