A menu provider is responsible for loading a menu when it is requested. KnpMenu
supports having several providers. The CmfMenuBundle provides the
PhpcrMenuProvider to load menu items using Doctrine PHPCR-ODM.
Every menu is identified by the name of the root node. The provider looks for
the root node under the the path configured in
cmf_menu.persistence.phpcr.menu_basepath. This defaults to /cmf/menu.
In order to get a menu located at /cms/menu/main-menu, you use the
identifier main-menu. You can also use an absolute path to load menus that
are not located under the menu basepath.
You can use custom document classes for menu nodes if needed, as long as
they implement Knp\Menu\NodeInterface.
There is currently no support for Doctrine ORM or other persistence
managers. This is not by design, but only because nobody built that yet.
We would be glad for a pull request refactoring PhpcrMenuProvider into
a base class suitable for all doctrine implementations and storage specific
