Now that we’re logged in, how can we get access to the User object?
Open up the homepage template. In Twig, we can access the User object by calling app.user. Let’s use it to print out the username:
{# src/Yoda/EventBundle/Resources/views/Event/index.html.twig #}
{# ... #}
{% if is_granted('IS_AUTHENTICATED_REMEMBERED') %}
<a class="link" href="{{ path('logout') }}">
Logout {{ app.user.username }}
</a>
{% endif %}
Tip
If the user isn’t logged in, app.user will be null. So be sure to check that the user is logged in first before using app.user.
From a controller, it’s just as easy. Go to the controller function for the homepage and grab an object called the security context. Then call getToken() and getUser():
public function indexAction()
{
$user = $this->container
->get('security.context')
->getToken()
->getUser()
;
var_dump($user->getUsername());die;
// ...
}
Actually, since this is a bit long, the Symfony base controller gives us a shortcut method called getUser:
public function indexAction()
{
$user = $this->getUser();
var_dump($user->getUsername());die;
// ...
}
I showed you the longer option first so that you’ll understand that there is a service called security.context which is your key to getting the current User object. Remove this debug code before moving on.
