Save elements when using the session Symfony

I am trying to use the session with Symfony.
In fact, I want to complete a form before login.

For this reason, I would like this scheme:

  1. Save the different fields in the session
  2. Login/register
  3. Save in the database


My controller: 

    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()
        ));
    }

The solution of Antoine is right,

You will have to serialize the object in order to be able to store it in the session.
The easiest way should be using the JMSSerializerBundle and decode your object as json:

$serializer = $this->container->get('serializer');
$jsonDecoded = $serializer->serialize($doctrineobject, 'json');

Btw. as stated in the comments this will serialize the whole doctrine structure connected to the entity.
However a toArray() function could be implemented into the entity in order to serialize an array structure only, but this approach becomes very complex when dealing with oneToOne oneToMany and manyToMany relationships

I do not think you can store an object in a session. Here are a few solutions :

  1. store manually each field of your object in the session
  2. serialize your object and save it in the session
  3. store it in the database with a flag saying it is not yet attached to a user, and save the id in session

As I see it, 1 is the fastest to implement, but it will be a pain to maintain if you later add fields to your entity. Solution 2 is better, but the deserialization is not so easy. I think solution 3 is the best, it is not that complicated to implement and will not cause any maintainance issue.

If you want to save the data, save only the input data from the form (after validation) and not the entirely entity (with possibly a lot of... shit, unless that is what you want).

You can just set the object/array into the session and Symfony will take care of serializing and unserializing it for you

If this is the case, replace

$session->set('infos', $CustomMade);

by

$session->set('infos', $form->getData());

This way you'll be later simply do:

$data = $session->get('infos');
