knpmenubundle: How to get user data in builder?

Question

How can I get User data in theKnpMenuBundle's Builder?

I know I can get the user data via this line in Controller:

$user = $this->get('security.context')->getToken()->getUser();

but I want it to get in my menu builder aswell, so I can put the username in the menu.

Answer 1

Your MenuBuilder is defined as a service in Symfony2, as you can see in https://github.com/KnpLabs/KnpMenuBundle/blob/master/Resources/doc/menu_service.rst

Basically, all you need to do is configure your MenuBuilder service definition to inject the security context. (http://symfony.com/doc/current/book/service_container.html#referencing-injecting-services)

Simshaun is totaly right. After some research i manage to do it like this :

1. Add the injection on services.yml :

   administration_main.menu.main:
     class: Knp\Menu\MenuItem
     factory_service: administration_main.menu_builder
     factory_method: createAdministrationMainMenu
     arguments: ["@request","@security.context"]
     scope: request
     tags:
         - { name: knp_menu.menu, alias: administrationMain }
   

2. Use it on the menu builder

   use Symfony\Component\Security\Core\SecurityContext;
   
   public function createAdministrationMainMenu(Request $request, SecurityContext $securityContext){
   
     $securityContext->getToken()->getUser();
   
   }
