Symfony 2 FOSFacebookBundle user redirection before login

Question

I use FOSUserBundle and FOSFacebookBundle (for version SF 2.0.x) in my project. In addition, I implemented a custom FacebookProvider, as described in the FOSFacebookBundle documentation. I would like to get the following workflow: 1.) The user visits my portal for the first time 2.) He clicks the Facebook-Login-Button 3.) Now I need to check if this user has clicked the Facebook-Login-Button, I already have Facebook Friends on my portal. 4.) If he has friends, redirect him to the registration page (including information from Facebook, for example, username, username, filename, etc.) with pre-filled input fields. 5.) If he does not have Facebook friends on my portal, redirect him to another page

I started looking at Webprofiler what events are causing. I started creating my own event listener, as described on this page: http://www.dobervich.com/2011/10/13/login-redirection-revisited/ , but the profile shows me my listener in the list of "non-invoked listeners" : security.interactive_login SecurityListener :: onSecurityInteractiveLogin

Does anyone know how I can configure this pre-login check and redirect the user to the page?

It would be great to help you with this.

Thanks Ramo

You need to set up your own authentication success handler. Configure a service that implements AuthenticationSuccessHandlerInterface :

facebook_auth_success_handler: class: MyHandler public: false arguments: # your dependencies... 

Then add this handler to security.yml in the fos_facebook block:

 firewalls: foo: fos_facebook: success_handler: facebook_auth_success_handler 

The handler itself should look something like this:

 public function onAuthenticationSuccess(Request $request, TokenInterface $token) { $user = $token->getUser(); $hasFriendsHereAlready = // your logic here if ($hasFriendsHereAlready) { $route = 'foo'; } else { $route = 'bar'; } return new RedirectResponse($this->router->generate($route)); }
