FOSUserBundle - How to redirect already logged-in users when trying to access the login_path

Question

Is it possible to perform an automatic redirect to the some route (i.e. /) for the specific route /login only for users that are AUTHENTICATED? and

Answer 1

As you are using FOSUserBundle the rendering of the login form takes place in SecurityController::renderLogin().

The solution is bascially:

• overriding the SecurityController
• adding a check for the role IS_AUTHENTICATD_ANONYMOUSLY
• redirecting the user to another page if the role was not found

I assume you have already created a bundle extending FOSUserBundle which holds your User Entity.

I assume this bundle is called YourUserBundle and is located at src/Your/Bundle/UserBundle.

Now copy (not cut) the SecurityController

vendor/friendsofsymfony/user-bundle/src/FOS/UserBundle/Controller/SecurityController.php

to (in order to override the one provided by FOSUserBundle)

src/Your/Bundle/UserBundle/Controller/SecurityController.php

add the use-statement for RedirectResponse and edit the renderLogin() method like this:

use Symfony\Component\HttpFoundation\RedirectResponse;

// ...

protected function renderLogin(array $data)
{
    if (false === $this->container->get('security.context')->isGranted('IS_AUTHENTICATED_ANONYMOUSLY')) {
        return new RedirectResponse('/', 403);
    }

    $template = sprintf('FOSUserBundle:Security:login.html.%s', $this->container->getParameter('fos_user.template.engine'));

    return $this->container->get('templating')->renderResponse($template, $data);
}

Update

Now instead of security.context use security.authorization_checker.
