symfony doctrine find User by Email - symfony

Question

ok, with
$user = $this->getDoctrine()
->getRepository('UserBundle:User')
->find($user_id)
I get an User by the given Identifier (ID).
but how can I get him by given email?
$emailCheck = $em->createQueryBuilder('u')
->select('u, r')
->where('u.email = :email')
->setParameter('email','test#email.com')
->getQuery();
Whill it return an array or an object? Is this the right way to handle it?

Answer 1

This will return a User object.
$user = $this->getDoctrine()
->getRepository('UserBundle:User')
->findOneByEmail($email);

Answer 2

You can use either
$user = $this->getDoctrine()
->getRepository('UserBundle:User')
->findBy(array('email' => $email));
To load an array of User entities. (Will always be a list, even with 0 or 1 results.)
Or you can do:
$user = $this->getDoctrine()
->getRepository('UserBundle:User')
->findOneBy(array('email' => $email));
This will return the first found result as a User entity object.
You can use the getOneOrNullResult(), as well, it's the long variant. Note however that you should always use setMaxResults(1) with this, otherwise you'll get an exception if more than one result is found (SF 2.3.x).

Answer 3

Either you use the magic method of Doctrine findOneByyour_field or you can create your own method in your repo
public function findOneByEmailAndStoreId($email, $store_id)
{
$q = $this->createQueryBuilder('c')
->where('c.email = :email')
->andWhere('c.store_id = :store_id')
->setParameter('email', $email)
->setParameter('store_id', $store_id)
->getQuery();
return $q->getOneOrNullResult(); // will return only one result or null 'getResult' will return a collection
}
