How can i access the user Role in Form Builder class in Symfony2

Pretty simple. Just make your custom form type a service, depending on the security context:

use Symfony\Component\Security\Core\SecurityContext;class UserType extends AbstractType{    private $securityContext;    public function __construct(SecurityContext $securityContext)    {        $this->securityContext = $securityContext;    }    public function buildForm(FormBuilder $builder, array $options)    {        // Current logged user        $user = $this->securityContext->getToken()->getUser();        // Add fields to the builder    }    public function getDefaultOptions(array $options)    {        return array(            'required'   => false,            'data_class' => 'Acme\HelloBundle\Entity\User'        );    }    public function getName()    {        return 'user_type';    }}

Then mark the class as a service, with the special tag form.type:

services:    form.type.user:        class: Acme\HelloBundle\Form\Type\UserType        arguments: ["@security.context"]        tags:            - { name: form.type, alias: user_type }

In your controller, instead of doing new UserType(), grap the service from the container:

$form = $this->createForm($this->get('form.type.user'), $data);
