Implementation of the Hierarchical Select API that allows one to use a hardcoded hierarchy. When it becomes to slow, you should move the hierarchy into the database and write a proper implementation.

Code

function hs_smallhierarchy_hierarchical_select_valid_item($item, $params) {
  $hierarchy = _hs_smallhierarchy_transform($params['hierarchy'], $params['id'], $params['separator']);

  // All valid items are in the keys of the $hierarchy array. Only the fake
  // "root" item is not a valid item.
  $items = array_keys($hierarchy);
  unset($items['root']);
  return in_array($item, $items);
}
