public function MenuLinkManager::getParentIds in Drupal 8

Same name and namespace in other branches

9 core/lib/Drupal/Core/Menu/MenuLinkManager.php \Drupal\Core\Menu\MenuLinkManager::getParentIds()

Loads all parent link IDs of a given menu link.

This method is very similar to getActiveTrailIds() but allows the link to be specified rather than being discovered based on the menu name and request. This method is mostly useful for testing.

Parameters

string $id: The menu link plugin ID.

Return value

array An ordered array of IDs representing the path to the root of the tree. The first element of the array will be equal to $id, unless $id is not valid, in which case the return value will be NULL.

Overrides MenuLinkManagerInterface::getParentIds
