Selecting all children of a given taxonomy term can be a pain. This module makes it easier to do this, by maintaining a complete list of edges for each term using the adjecency matrix graph theory.

Code

function taxonomy_edge_is_order_valid($vid, $reset = FALSE) {
  static $valid_orders = array();
  if ($reset || !isset($valid_orders[$vid])) {
    $valid_orders[$vid] = db_result(db_query_range("SELECT 1 FROM {term_edge_order} WHERE vid = %d", -$vid, 0, 1));
  }
  return $valid_orders[$vid];
}
