Question

MyEntityType：

public function buildForm(FormBuilderInterface $builder, array $options) {
        $em = $this->em;
        $em = $options['entity_manager'];
        $builder
            ->add('title')
            ->add('photo', FileType::class)
            ->add('kitchen', EntityType::class, array(
                'class' => 'DeliveryAdminBundle:Kitchen',
                'multiple' => true,
                'query_builder' => function (\Delivery\AdminBundle\Repository\KitchenRepository $er) {
                    return $er->createQueryBuilder('k')
                        ->orderBy('k.title', 'ASC');

                },
                'data' => ['16'=>'Японская'],        
            ))
            ->add('specialization', EntityType::class, array(
                'class' => 'DeliveryAdminBundle:Specialization',
                'multiple' => true,
                'query_builder' => function (\Delivery\AdminBundle\Repository\SpecializationRepository $er) {
                    return $er->createQueryBuilder('k')
                        ->orderBy('k.title', 'ASC');

                },
            ))
            ->add('type', EntityType::class, array(
                'class' => 'DeliveryAdminBundle:EntityType',
                'multiple' => false,
                'query_builder' => function (\Delivery\AdminBundle\Repository\EntityTypeRepository $er) {
                    return $er->createQueryBuilder('k')
                        ->orderBy('k.title', 'ASC');

                },
            ))
            ->add('save', SubmitType::class, array('label'=>'Отправить'));
    }

控制器操作：

    public function newAction(Request $request) {
        $em = $this->getDoctrine()->getManager();
        $repo = $em->getRepository('DeliveryAdminBundle:MyEntity');

        $entity = new MyEntity();
        $form = $this->createForm(MyEntityType::class, $entity, [
            'entity_manager' => $this->get('doctrine.orm.entity_manager')
        ]);

        $form->handleRequest($request); // ERROR !!!

        if ($form->isSubmitted() && $form->isValid()) {
            $repo->update($entity, $request->request->get('id'));

            return $this->redirectToRoute('show_myentity');
        }

        return $this->render( 'DeliveryAdminBundle:Entity:new.html.twig', 
                array('form'=>$form->createView()) );
    }

项目已发布https://github.com/zchipirov/delivery

设置表Kitchen-＆gt; MyEntity（OneToMany）和Specialization-＆gt; MyEntity（OneToMany）之间的通信。表“MyEntityKitchen”和“MyEntitySpecialization”联合MyEntity，Kitchen和Specialization

保存后我有错误：

Expected argument of type "Delivery\AdminBundle\Entity\MyEntitySpecialization", "Delivery\AdminBundle\Entity\Kitchen" given

堆栈：

if (null === $response) {
$msg .=' Did you forget to add a return statement somewhere in your controller?';
}
throw new \LogicException($msg);
}
}
return $this->filterResponse($response, $request, $type);

Answer 1

这是因为你有MyEntity课程：

/**
 * Add kitchen
 *
 * @param \Delivery\AdminBundle\Entity\MyEntitySpecialization $kitchen
 *
 * @return MyEntity
 */
public function addKitchen(\Delivery\AdminBundle\Entity\MyEntitySpecialization $kitchen)
{
    $this->kitchen[] = $kitchen;
    return $this;
}

并以表格形式提供：

->add('kitchen', EntityType::class, array(
    'class' => 'DeliveryAdminBundle:Kitchen',
    'multiple' => true,
    'query_builder' => function (\Delivery\AdminBundle\Repository\KitchenRepository $er) {
        return $er->createQueryBuilder('k')
            ->orderBy('k.title', 'ASC');
        },
    'data' => ['16'=>'Японская'],        
))

并且提交类\Delivery\AdminBundle\Entity\Kitchen的表单实体时会传递给MyEntity->addKitchen。没关系，但由于某种原因，你有类型：\Delivery\AdminBundle\Entity\MyEntitySpecialization，这就是PHP投掷Exception的原因。

将this line更改为：

public function addKitchen(\Delivery\AdminBundle\Entity\Kitchen $kitchen)

和this line：

public function removeKitchen(\Delivery\AdminBundle\Entity\Kitchen $kitchen)

Answer 2

我添加了代码：

/**
     * Add kitchen
     *
     * @param \Delivery\AdminBundle\Entity\MyEntitySpecialization $kitchen
     *
     * @return MyEntity
     */
    public function addKitchen(\Delivery\AdminBundle\Entity\MyEntitySpecialization $kitchen, \Delivery\AdminBundle\Entity\MyEntitySpecialization $specialization)
    {
        $this->kitchen[] = $kitchen;
        $this->specialization[] = $specialization;

        return $this;
    }

    /**
     * Remove kitchen
     *
     * @param \Delivery\AdminBundle\Entity\MyEntitySpecialization $kitchen
     */
    public function removeKitchen(\Delivery\AdminBundle\Entity\MyEntitySpecialization $kitchen, \Delivery\AdminBundle\Entity\MyEntitySpecialization $specialization)
    {
        $this->kitchen->removeElement($kitchen);
        $this->specialization->removeElement($specialization);
    }

谢谢，它有效！

如何将Form中的数据保存到多个表中（从MyEntityType到MyEntity，MyEntityKitchen和MyEntitySpecialization）？ 保存后我收到错误：

Expected value of type "Doctrine\Common\Collections\Collection|array" for association field "Delivery\AdminBundle\Entity\MyEntity#$kitchen", got "Delivery\AdminBundle\Entity\Kitchen" instead.

保存表格后出错[Symfony3]
