Code

function menu_node_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
  $watch = array(
    'insert',
    'update',
    'delete',
    'load',

  // Do we care about this node?
  if (!in_array($op, $watch)) {
    return;

  // On delete operations, the menu item may be deleted before this
  // runs, so ensure we have the data.
  if ($op == 'load') {

    // Ensure the menu object is loaded.
    $node->menu_node_items = menu_node_get_links($node->nid);
  }
  $mlid = isset($node->menu['mlid']) ? $node->menu['mlid'] : NULL;

  // If the node is being deleted, remove all records.
  if ($op == 'delete') {
    menu_node_delete($node);
  }

    // If we have a record to insert, then do so now.
