I've read documentations and examples from few sources but still can't get this HWIOAuthBundle works. I've login form using user ID and password which added manually in Admin section that already works fine.

I want to add Binding Facebook Button in User Area after they login successfully, so they can login with normal ID/Password either Facebook Login in future. I've searching about this HWIOAuthBundle but can't find any similar case like this.

  // 3. Not logged into Facebook and can't tell if they are logged into
  //    your app or not.
  //
  // These three cases are handled in the callback function.

  }(document, 'script', 'facebook-jssdk'));

  // Here we run a very simple test of the Graph API after login is
  // successful.  See statusChangeCallback() for when this call is made.
  function testAPI() {
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
      console.log('Successful login for: ' + response.name);

        'Thanks for logging in, ' + response.name + '!';

  1. How to get Facebook ID and Access token and saved into database (for binding Facebook)
  2. How to check in database for Facebook ID. If Exist, give ROLE_USER like normal loginAction in my Controller. If not exist throw exception.
  3. If this Bundle can't accommodate my problems, is there any better Bundle or function which fit for my needs?

You need to create your own provider, which implements OAuthAwareUserProviderInterface. In loadUserByOAuthUserResponse method from $response parameter you can get any info about Facebook-user. Example:

class MyOAuthProvider implements UserProviderInterface, OAuthAwareUserProviderInterface
{
    public function loadUserByOAuthUserResponse(UserResponseInterface $response)
    {
        $token = $response->getAccessToken();
        $facebookId =  $response->getUsername(); // Facebook ID, e.g. 537091253102004
        $username = $response->getRealName();
        $email = $response->getEmail();

        // search user in database
        $result = $this->em->getRepository('AppUserBundle:User')->findOneBy(
            array(
                'facebookId' => $facebookId
            )
        );

        if(!$result) {
            $user = new User();
            $user->setEmail($email);
            $user->setUsername($username);
            $user->setFacebookId($facebookId);

            // ..
            // save to database instructions
            // ..
        }

        return $this->loadUserByUsername($username);
    }

    // other methods
}

Don't forget specify your custom provider in app/config/config.yml

services:
    app.user.provider:
        class: App\UserBundle\Entity\MyOAuthProvider

and in app/config/security.yml

firewalls:
        ...
        user_area_socials:
            oauth:
                oauth_user_provider:
                    service: app.user.provider
