I've got a node, I want it's menu. As far as I can tell, node_load doesn't include it. Obviously, it's trivial to write a query to find it based on the path node/nid
, but is there a Drupal Way to do it?
if the menu tree has multiple levels sql seems a better option. a sample for drupal 7 is given bellow where path is something like 'node/x'
function _get_mlid($path, $menu_name) {
$mlid = db_select('menu_links' , 'ml')
->condition('ml.link_path' , $path)
->condition('ml.menu_name',$menu_name)
->fields('ml' , array('mlid'))
->execute()
->fetchField();
return $mlid;
}
The Menu Node module exposes an API to do this.
You can read the documentation (Doxygen) in the code. I think the functionality you need is provided by the menu_node_get_links($nid, $router = FALSE)
method:
/**
* Get the relevant menu links for a node.
* @param $nid
* The node id.
* @param $router
* Boolean flag indicating whether to attach the menu router item to the $item object.
* If set to TRUE, the router will be set as $item->menu_router.
* @return
* An array of complete menu_link objects or an empy array on failure.
*/
An associative array of mlid => menu object
is returned. You probably only need the first one so it might look like something like this:
$arr = menu_node_get_links(123);
list($mlid) = array_keys($arr);
Otherwise, you can try out the suggestion in a thread in the Drupal Forums:
Use node/[nid]
as the $path argument for:
function _get_mlid($path) {
$mlid = null;
$tree = menu_tree_all_data('primary-links');
foreach($tree as $item) {
if ($item['link']['link_path'] == $path) {
$mlid = $item['link']['mlid'];
break;
}
}
return $mlid;
}
