Question

我有三个实体，一个用户，一个类别和一个事件，一个用户可以在许多类别中被强制插入，一个事件可以有一个类别。

user.php的：

命名空间Mql14 \ mqlmeBundle \ Entity;

将Doctrine \ ORM \ Mapping用作ORM;

/**
 * Mql14\mqlmeBundle\Entity\User
 *
 * @ORM\Table(name="user")
 * @ORM\Entity
 */
class User
{
/**
 * @var integer $id

 */
private $id;

/**
 * @var string $nom
 *
 * @ORM\Column(name="nom", type="string", length=45, nullable=true)
 */
private $nom;

/**
 * @var string $prenom
 *
 * @ORM\Column(name="prenom", type="string", length=45, nullable=true)
 */
private $prenom;

/**
 * @var string $login
 *

 */
private $login;

/**

 *   },

 */
private $categorie;

public function __construct()
{
    $this->categorie = new \Doctrine\Common\Collections\ArrayCollection();
}

    {
        return $this->lieu;
    }




    public function getCategorieId(\Mql14\mqlmeBundle\Entity\Categorie $categorie)
    {
        $idc= $categorie->getId();
        return $idc;
    }

     }

现在我的控制器中的动作允许我在获得用户的id和他所关注的类别后显示事件（evenements）（参数$ id是用户＆＃39; s id）：

 public function interetAction($id)
    {

        $em = $this->getDoctrine()->getEntityManager();

        $users = $em->getRepository('Mql14mqlmeBundle:User')->find($id);
    foreach($users->getCategorie() as $cat) {

    $events=$cat->getEvenement();

}


return $this->container->get('templating')->renderResponse('Mql14mqlmeBundle:Event:interet.html.twig', array(

        'categoriesEvents' => $events,
));

    }

但即使用户在许多类别中被强制执行此操作，显示的事件也只有一个类别，因此我应该怎么做才能显示特定用户所有类别的所有事件inressted in

Answer 1

在您的控制器中： $events=$cat->getEvenement(); 将其更改为： $events[]=$cat->getEvenement();

在foreach循环中，每次都覆盖$ events变量。
