我的控制器：

public function customMadeAction(Request $request)
    {
        $session = $this->container->get('session');

        $user = $this->container->get('security.context')->getToken()->getUser();

        $CustomMade = new CustomMade();
        $form = $this->createForm(new CustomMadeType(),$CustomMade);

        $form->handleRequest($request);

        if ($user === 'anon.') {
            if($form->isValid()) {

                # 1-Save in session
                var_dump($CustomMade); #I have an array with all I need
                $session->set('infos',$CustomMade); #It does not save my informations

                # 2-Redirect to login/register
                $securityContext = $this->container->get('security.context');
                if (!$securityContext->isGranted('ROLE_USER')) {
                    throw new AccessDeniedException('Accès refusé');
                } else {

                # 3-Save in database
                $em = $this->getDoctrine()->getManager();
                $em->persist($CustomMade);
                $em->flush();
                }
            }
        }else{
            if($form->isValid()) {
                $CustomMade->setIdUser($user->getId());
                $em = $this->getDoctrine()->getManager();
                $em->persist($CustomMade);
                $em->flush();
            }
        }
        return $this->render('FrontBundle:Forms:customMade.html.twig',array(
            'form' => $form->createView()
        ));
    }
