php - 如何从symfony3中的同一表单访问2个表？

Question

我有一个 Controller 。我在该 Controller 中有一个表单。我希望从表(状态表)中以下拉形式接收表单中的数据，并在单击创建时将从该状态表接收到的数据发送到另一个表(站点表)。两个表都在同一个数据库中。那么我该如何在 symfony 中做到这一点呢？

Controller

public function createAction(Request $request)
    {

        $site = new site;

        $form = $this->createFormBuilder($site)

            ));
    }

我想要来自 的下拉菜单转到类别字段中的 site_table (我对站点表进行了硬编码)

您应该首先创建一个 FormType，然后使用 EntityType 作为下拉列表，如下所示:

class MyFormType extends AbstractType{    /**     * @param FormBuilderInterface $builder     * @param array $options     */    public function buildForm(FormBuilderInterface $builder, array $options)    {        $builder            ->add('type', EntityType::class, [                'label' => 'State',                'class' => YourStateEntity::class            ]);    }    public function configureOptions(OptionsResolver $resolver)    {        $resolver->setDefaults([            'data_class' => YourSiteEntity::class        ]);    }}

查看“YourStateEntity”和“YourSiteEntity”，并替换为与您的“州”表和“站点”表相对应的您自己的实体。

然后在你的 Controller 中:

    public function createAction(Request $request, EntityManagerInterface $entityManager)    {        $site = new YourSiteEntity();        $form = $this->createForm(MyFormType::class, $site);        $form->handleRequest($request);        if ($form->isSubmitted() && $form->isValid()) {            $entityManager->persist($site);            $entityManager->flush();            return $this->redirectToRoute('site_list');        }        return $this->render('sites/create.html.twig', [            'form' => $form->createView(),            'site' =>  $site        ]);    }

这是推荐的方式。将所有字段放入“MyFormType”中，然后让 Symfony 完成它的工作。
