Code

function _taxonomy_edge_taxonomy_term_update($term) {
  $tx = _taxonomy_edge_db_transaction();

  // Invalidate sorted tree in case of name/weight change
  if (isset($term->original) && ($term->original->name != $term->name || $term->original->weight != $term->weight)) {
    taxonomy_edge_invalidate_order($term->vid);
  }
  if (!isset($term->parent)) {

    // Parent not set, no need to update hierarchy.
    return;
  }

  // Derive proper parents.
  $parents = _taxonomy_edge_unify_parents($term->parent);
  _taxonomy_edge_move_subtree($term->vid, $term->tid, $parents);
