Question

I’m trying to modify the way FOSUSerBundle validates the username/email when the user registers, because I need to check if the user was previously registered, but he has unsubscribed, through status flag in the entity. I think the best way is check if email is previously on the database, excluding those who the flag unsubscribed is set to true, but how I do this?

So, I see how validates with UniqueValidator class, but I don’t understand how it works. It would be great if anyone could explain it too.

Thanks.

Answer 1

UniqueValidator calls validateUnique method of UserManager class. You can extend the class and modify the function to check user

$this->findUserByEmail($user->getEmail());

Edit

For second question, you have to override UpdateUser method of the UserManager class.

/**
 * Updates a user.
 *
 * @param UserInterface $user
 * @param Boolean $andFlush Whether to flush the changes (default true)
 */
public function updateUser(UserInterface $user, $andFlush = true)
{
    $existsUser = $this->findUserByEmail($user->getEmail()); 
    $this->updateCanonicalFields($user);
    $this->updatePassword($user);

    if($existsUser && null === $user->getId()){
        $user->setId($existsUser->getId());
        $this->em->merge($user);
    } else{
        $this->em->persist($user);
    }

    if ($andFlush) {
        $this->em->flush();
    }
}
