Symfony2 Forms: Retrieving data from entity field

Question

I feel like I am missing something obvious here, I have an entity form field that gives a list of users to select from , the idea here is creating a project and associate it with that (or several) users. I achieved this without much problems but I can't figure out how to access and work with that form field.

Here's how I am setting the form field:

->add('user', 'entity', array(
'class' => 'DevUserBundle:User',
'label'  => 'Assigned Users: ',
'multiple'=> true,))

In the controller I do the following:

$data = $form->getData();

I can access the field with $data['user'] but beyond that I am lost.

To see which user has been selected, the synthax is similar to what you suggested:

$usersSelected = $form["user"]->getData();

EDIT

The reason why you have such a long list in your print_r($userSelected) statement is because $userSelected is an array of User objects. Indeed, as you can see in your builder: ->add('user', 'entity'...)

You can verify this this way

$i = 1;
foreach ($usersSelected as $user)
{
    echo "User number ".$i;
    echo get_class($user);
    //Assuming that you have the method getUsername() in you User entity
    echo "Username is".$user->getUsername();
    $i++;
}

doing print_r on this gives a very long winded object which I was having problems with before, how do I navigate this object to get the usernames selected?
