Html_Menu with Nested Set

Hi, I just can not get it right. Here is my menu.php <?php require_once('HTML/Menu.php'); require_once('DB/NestedSet.php'); require_once('DB/NestedSet/Output.php'); $dsn = 'mysql://root:test@localhost/test'; $params = array( 'id' => 'id', 'parent_id' => 'rootid', 'left_id' => 'l', 'right_id' => 'r', 'order_num' => 'norder', 'level' => 'level', 'id_trans' => 'id_trans', 'url' => 'url', 'name' => 'name', ); $nestedSet =& DB_NestedSet::factory('DB', $dsn, $params); // we want the nodes to be displayed ordered by name, so we add the secondarySort attribute $nestedSet->setAttr(array( 'node_table' => 'nested_set', 'lock_table' => 'nested_set_locks', 'secondarySort' => 'name', ) ); // get data (important to fetch it as an array, using the true flag) $data = $nestedSet->getAllNodes(true); // }}} // {{{ manipulate data // add links to each item foreach ($data as $id => $node) { $data[$id]['url'] = $data[$id]['url'].'?nodeID='.$node['id']; } // }}} // {{{ render output $params = array( 'structure' => $data, 'titleField' => 'name', 'urlField' => 'url'); // Create the output driver object $output =& DB_NestedSet_Output::factory($params, 'Menu'); // Fetch the menu array $structure = $output->returnStructure(); // Instantiate the menu object, we presume that $data contains menu structure $currentUrl = $_SERVER['PHP_SELF'].'?nodeID='.$_GET['nodeID']; ?> I made an extra column url in the database and assigned the urls like this: foreach ($data as $id => $node) { $data[$id]['url'] = $data[$id]['url'].'?nodeID='.$node['id']; } After I have done that the menu doesn't expand anymore. I include the above script in for example news.php include('menu.php'); $menu = & new HTML_Menu($structure, 'sitemap'); // Force menu to understand the nodeID passed with the request $menu->forceCurrentUrl($currentUrl); $menu->setMenuType('urhere'); $menu_urhere = str_replace('border="1"', 'border="0"', $menu->get()); $page->assign('menu_urhere', $menu_urhere); $menu->setMenuType('tree'); $menu_tree = str_replace('border="1"', 'border="0"', $menu->get()); $page->assign('menu_tree', $menu_tree); How can I assign the urls from the database properly ? Thank you.
