使用带有 FOSUserBundle 的 Groups 获取 group_id

Question

我已经配置了 FOSUserBundle 组，关注Using Groups With FOSUserBundle 并让它工作。

// 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;

每次它创建一个新的User，我都可以使用：

$userObj = new \SM4\UserBundle\Entity\User;

$userObj->getId();

$userObj->getEmail();

....

$userObj->getGroup();

但是如何获取用户的Group_id？

Answer 1

假设您的User 实体中有如下功能：

public function getGroups()
{
    return $this->groups;
}

另外一个在你的Group 实体中如下：

public function getId()
{
    return $this->id;
}

而$this->groups 是您的User 实体中的ArrayCollection 对象，您可以这样做：

foreach ($userObj->getGroups() as $group)
{
    //this is where you get your groups id
    echo $group->getId();
}

如何打印连接表的输出？ ([group:Hta\CoreBundle\Entity\HtaUser:private] => Doctrine\ORM\PersistentCollection 对象 递归 )
