这里是FormType最后一个级别：
MentionsLegalesNv1Type：
class MentionLegaleNv1Type extends AbstractType {

*/
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('MentionsLegalesNv2', 'collection', array(

MentionsLegalesNv2Type：

*/
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('titre', 'text', array(

MentionsLegalesNv3Type：

*/
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder

/**

public function getName() {

}
}
而且我的控制器：
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(),
));
}
}
我发现的Symfony的食谱（http://symfony.com/doc/current/cookbook/form/form_collections.html），我试过，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' => $form->createView(),
));
}
}
如何删除MentionLegaleNv2或MentionLegaleNv3中的项？
感谢您的帮助！
您好！感谢您的帮助...我尝试了您的解决方案，但我有这个错误消息：“尝试在/Users/thomasmelcer/Sites/Video2Learn.fr/src类”Video2Learn \ BddBundle \ Entity \ MentionLegaleNv2“上调用方法setMentionLegaleNv1” /Video2Learn/BddBundle/Entity/MentionLegaleNv1.php第89行。您是否打算调用：“addMentionsLegalesNv3”，“getMentionsLegalesNv1”，“getMentionsLegalesNv3”，“setMentionsLegalesNv1”？“ – Zagloo
哦，没关系......这是你写的，但用（'s'）这样“$ mentionsLegalesNv2-> setMentionSLegaleSNv1（null）;” 因此，解决方案工作但是，我想删除数据库中，不只是将其设置为NULL，因为它始终存在于数据库中... – Zagloo
