Getting the group_id by using Groups with FOSUserBundle - symfony

Question

I have configured the FOSUserBundle Group follow Using Groups With FOSUserBundle and get it to work.
// src/SM4/UserBundle/Entity/User.php
/**
* #ORM\ManyToMany(targetEntity="SM4\UserBundle\Entity\Group")
* #ORM\JoinTable(name="sm4_user_group",
* joinColumns={#ORM\JoinColumn(name="user_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="group_id", referencedColumnName="id")}
* )
*/
protected $groups;
Every time it creates a new User, I can use:
$userObj = new \SM4\UserBundle\Entity\User;
$userObj->getId();
$userObj->getEmail();
....
$userObj->getGroup();
But how do I get the Group_id of user?

Answer 1

Assuming you have a function as follow in your User entity:
public function getGroups()
{
return $this->groups;
}
and another one as follow in your Group entity:
public function getId()
{
return $this->id;
}
and that $this->groups is an ArrayCollection object in your User entity, you can do:
foreach ($userObj->getGroups() as $group)
{
//this is where you get your groups id
echo $group->getId();
}
