Doctrine 2: Can entities be saved into sessions?

Question

I\'m having a problem with lazy loading after I save an entity into a PHP session. Is there any workaround for this?

Answer 1

The accepted answer quotes accurately the Doctrine documentation.

However, there are few more pages on the subject explaining how to serialize entities and store them the session. Entities in the Session says that the entities must be detached before storing in the session and then merged when restoring from the session.

On this page there are sections about detaching and merging entities.

Saving:

$em = GetEntityManager();
$user = $em->find("User", 1);
$em->detach($user);
$_SESSION['user'] = $user;

Restoring:

$em = GetEntityManager();
session_start();
if (isset($_SESSION['user']) && $_SESSION['user'] instanceof User) {
    $user = $_SESSION['user'];
    $user = $em->merge($user);
}
