我正在尝试删除表单中的项目，但没有任何反应（甚至没有错误......但我可以毫无问题地进行编辑！）
我有一个嵌入了3个级别的表单集合（它是关于我的网站的法律声明分为子级别）
以下是我的实体：
OneToMany中名为“MentionLegaleNv1”的第一级
class MentionLegaleNv1 {
/**
* @ORM\Column(name="id", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**

*/
private $titre;
/**
* @ORM\OneToMany(targetEntity="MentionLegaleNv2", mappedBy="MentionsLegalesNv1", cascade={"persist", "remove"})
*/
private $MentionsLegalesNv2;
/**

*/
public function __construct() {
$this->MentionsLegalesNv2 = new \Doctrine\Common\Collections\ArrayCollection();
}

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

}
/**

以下是FormType：
提及LegalesNv1Type：

提及LegalesNv2Type：

提及LegalesNv3Type：

我的控制员：
class MentionsLegalesController extends Controller {
public function mentionLegalesAction(Request $request) {
$em = $this->getDoctrine()->getManager();
$ML = $em->getRepository('Video2LearnBddBundle:MentionLegaleNv0')->findOneById(1);
if ($request->getMethod() == 'GET') {
$form = $this->createForm(new MentionLegaleNv0Type(), $ML);
}
if ($request->isMethod('POST')) {
$form = $this->createForm(new MentionLegaleNv0Type(), $ML);
$form->handleRequest($request);
if ($form->isValid()) {
$ML = $form->getData();
$em->persist($ML);
$em->flush();
return $this->redirect($this->generateUrl('administration_mentions_legales'));
}
}
return $this->render('Video2LearnAdministrationBundle:Pages:mentions_legales.html.twig', array(
'form' => $form->createView(),
));
}
}
我发现在Cookm of Symfony（http://symfony.com/doc/current/cookbook/form/form_collections.html）中我尝试了但没有成功......
class MentionsLegalesController extends Controller {
public function mentionLegalesAction(Request $request) {
$em = $this->getDoctrine()->getManager();
$ML = $em->getRepository('Video2LearnBddBundle:MentionLegaleNv1')->findOneById(1);
foreach ($ML->getMentionsLegalesNv2() as $tag) {
$originalTags->add($tag);
}
if ($request->getMethod() == 'GET') {
$form = $this->createForm(new MentionLegaleNv1Type(), $ML);
}
if ($request->isMethod('POST')) {
$form = $this->createForm(new MentionLegaleNv1Type(), $ML);
$form->handleRequest($request);
if ($form->isValid()) {
foreach ($originalTags as $tag) {
if ($ML->getMentionsLegalesNv2()->contains($tag) == false) {
$em->persist($tag);
}
}
$em->persist($ML);
$em->flush();
return $this->redirect($this->generateUrl('administration_mentions_legales'));
}
}
return $this->render('Video2LearnAdministrationBundle:Pages:mentions_legales.html.twig', array(
'form' => $form->createView(),
));
}
}
如何删除MentionLegaleNv2或MentionLegaleNv3中的项目？
感谢您的帮助！
答案 0 :(得分：0)
您的删除方法应该以与添加方法相同的方式自动更新连接的对象。
/**
* Remove MentionsLegalesNv2
*
* @param \Video2Learn\BddBundle\Entity\MentionLegaleNv2 $mentionsLegalesNv2
*/
public function removeMentionsLegalesNv2(MentionLegaleNv2 $mentionsLegalesNv2) {
$this->MentionsLegalesNv2->removeElement($mentionsLegalesNv2);
$mentionsLegalesNv2->setMentionLegaleNv1(null);
}

我做了另一种方式...
我做到了：
if ($form->isValid()) {
// supprime la relation entre le tag et la « Task »
foreach ($originalMentionsLegalesNv1 as $mlnv2) {
if ($MentionsLegalesNv1->getMentionsLegalesNv2()->contains($mlnv2) == false) {
$em->remove($mlnv2);
}
}
$em->persist($MentionsLegalesNv1);
$em->flush();
