You need to inject the EntityManager into the constructor of your form type
class.
// in controller
$em = $this->get('doctrine')->getEntityManager();
$form = $this->get('form.factory')->create(new MyFormType($em));
// form type class
class MyFormType extends AbstractType
{
private $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
public function buildForm(FormBuilder $builder, array $options)
{
// do something with $this->em
// ...
}
}
