ZF2 Doctrine get manytomany relations with objectSelect - php

Question

I have multiple users, with multiple stores in a many to many relational database. Every user has multiple stores attached to them.
Now, i want to load all the storenames from a logged in user in a select form.
How can i do this?
My user entity:
namespace Application\Entity;
use BjyAuthorize\Provider\Role\ProviderInterface;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
use ZfcUser\Entity\UserInterface;

Ok i've figured it out with a custom repository.
Add a repositoryclass to your store entity
<?php
namespace Application\Entity;
use Doctrine\ORM\Mapping as ORM;

protected $id;

* #ORM\Column(type="string", name="storeName", length=255, unique=true, nullable=true)
*/
protected $storeName;
/**
* #var \Doctrine\Common\Collections\Collection
* #ORM\ManyToMany(targetEntity="Application\Entity\Product", inversedBy="stores")
* #ORM\JoinTable(name="product_store")
*/
protected $products;
/**
* #var \Doctrine\Common\Collections\Collection
* #ORM\ManyToMany(targetEntity="Application\Entity\Category", inversedBy="stores")

The object select
$this->add(array(

'options' => array(
'object_manager' => $objectManager,
'target_class' => 'Application\Entity\Store',
'label' => 'Selecteer winkel',
'column-size' => 'sm-9',

'property' => 'storeName',
'is_method' => true,
'find_method' => array(
'name' => 'storesByUser',
'params' => array(
'criteria' => array('id' => $userid),
),
),
),
));
My custom store repository
<?php
namespace Application\Repositories;
use Doctrine\ORM\EntityRepository;
use Doctrine\ORM\Query\ResultSetMapping;
use Doctrine\DBAL\Types\Type;
class StoreRepository extends EntityRepository
{
public function storesByUser(array $criteria){
return $this->createQueryBuilder('s')
->select('s')
->innerJoin("s.users", "u", "WITH", "u=:userid")
->setParameter("userid", $criteria['id'])
->getQuery()->getResult();
}
}
