Creating a custom user provider with symfony

Question

I'm trying to do my own custom user provider, but I'm stuck at this part of the Symfony tutorial (Create a User Provider).

What do I need to do at the $userdata variable? A database connection?

I don't know what I need to do at this place:

public function loadUserByUsername($username)
{
    // here
    // $userData = ...
    if ($userData) {
        //here too
        //$password = ...
        return new DomixBlogUser($username, $password, $salt, $roles)
    } else {
        throw new UsernameNotFoundException(sprintf('Username "%s" does not exist.', $username));
    }
}

edit #1

public function loadUserByUsername($username)
{
    $userData = $this->_em->getRepository("DomixBlogBundle:User")->findOneBy(array('username' => $username));
    var_dump($userData);
    if ($userData) {
        $salt = '54hg5g4hfjh4g5sdgf45gd4h84gjhdf54gf4g2f2gfdhggfdg';
        $password = $userData->getPassword().'{'.$salt.'}';

        return new DomixBlogUser($username, $password, $salt, $roles);
    } else {
        throw new UsernameNotFoundException(sprintf('Username "%s" does not exist.', $username));
    }
}

that's good?

Yes, most likely it would be from a database connection. Really though it could be from anywhere. What it's saying is that your loadUserByUsername method should get some "user data" from whatever location/service is storing your users based on the given username and then return that.

public function loadUserByUsername($username)
{
    $userData = $this->_em->getRepository("DomixBlogBundle:User")->findOneBy(array('username' => $username));

    if (null !== $userData) {

        return $userData;
    } else {
        throw new UsernameNotFoundException(sprintf('Username "%s" does not exist.', $username));
    }
}

You can see an example of this in the default symfony entity user provider.

so, I will be able to do: $this->getDoctrine()->getEntityManager()->getRepository('DomixBlogBundle:User')->find($username) ?

in order to have access to the entity manager you will need to inject it into the UserProviders constructor in the service definition. $this->getDoctrine() is only a helper method in the Controller.

see here for injecting the entity manager into your service stackoverflow.com/questions/10427282/…

for now, I wrote: $userData = $this->_em->getRepository("DomixBlogBundle:User")->findOneBy(array('username' => $username));, return null if no user (good). how I can use $password?
