symfony 3.1 registration email no FOSUser - symfony

Question

Nice to meet you.
I'm developping with Symfony 3.1.3 and I'm using the security system offered by the framework, no FOSUser neither Guard.
I have in my controller the typical function login:
public function loginAction(Request $request)
{
// This works
$authenticationUtils = $this->get('security.authentication_utils');
// get the login error if there is one
$error = $authenticationUtils->getLastAuthenticationError();
// last username entered by the user
$lastUsername = $authenticationUtils->getLastUsername();
return $this->render(
'security/loginForm_old.html.twig',
array(
// last username entered by the user
'last_username' => $lastUsername,
'error' => $error,
)
);
}
And I want to check if the user has activated his account. In the entity User I have the isActive attribute set to false by default and only with the link into the registration email is setted to true.
I have been searching for this issue without results and I'm sure this is something very common, everybody wants to check if the user's email is a good one.
Thanks.

Lets assume that you have an RegistrationController.php class where you store all code that manage about user's registration.
Create a function which sends email to user after registration:
public function sendConfirmationEmailMessage(User $user)
{
$confirmationToken = $user->getConfirmationToken();
$username = $user->getUsername();
$subject = 'Account activation';
$email = $user->getEmail();
$renderedTemplate = $this->templating->render('AppBundle:Emails:registration.html.twig', array(
'username' => $username,
'confirmationToken' => $confirmationToken
));
$message = \Swift_Message::newInstance()
->setSubject($subject)
->setFrom(MAILER_FROM)
->setReplyTo(MAILER_FROM)
->setTo($email)
->setBody($renderedTemplate, "text/html");
$this->mailer->send($message);
}
Create a route associated with function which takes an generated token as argument, then search user by that token and activate if user exist:
/**
* #Route("user/activate/{token}")
*/
public function confirmAction(Request $request, $token)
{
$em = $this->getDoctrine()->getManager();
$repository = $em->getRepository('AppBundle:User');
$user = $repository->findUserByConfirmationToken($token);
if (!$user)
{
throw $this->createNotFoundException('We couldn\'t find an account for that confirmation token');
}
$user->setConfirmationToken(null);
$user->setEnabled(true);
$em->persist($user);
$em->flush();
return $this->redirectToRoute('user_registration_confirmed');
}
Then when you have a function which actually registers the user you call the sendConfirmationEmailMessage as shown below:
public function registerAction(Request $request)
{
/* All the logic goes here: form validation, creating new user */
/* $user is created user */
sendConfirmationEmailMessage($user);
}
Anyway if isActive() function return false Symfony security system will prevent you from login. Your User entity should implement UserInterface.
