Question

我有一个包含3个字符串字段的实体电影。我已经创建了一个没有问题的创建实体A的表单，它很好。

现在我想在我的实体中逐个制作一个表格（逐行），并且能够更改我想要的字段，并一次性保存所有更改。

我尝试使用烹饪书“如何嵌入表单集合”，但它与我的问题不符：c /

以下是一些示例代码，用于解释我正在尝试做什么，但是哪些不起作用：

实体电影

 class Film
 {
     /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
     private $id;

/**
 * @ORM\Column(type="string",nullable=false)
 */
private $name;

/**
 *
 * @ORM\Column(type="string")
 */
private $style;

/**
 * @ORM\Column(type="string")
 */
private $director;

/**
 * @ORM\Column(type="string")
 */
private $actor;

控制器电影

 public function updateAction(Request $request)
 {

    $films = $this->getDoctrine()
                  ->getRepository('LfayBundle:Film\Film');
    $films_all = $films->findAll();

    foreach ($films_all as $film) {
        $form = $this->createForm(FilmType::class, $film);
        $forms[] = $form->createView();
    }

    $form_film->handleRequest($request);
    if ($form_film->isSubmitted() && $form_film->isValid()) {

        $em = $this->getDoctrine()->getManager();
        $em->persist($films_all);
        $em->flush();

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

    return $this->render(
      'film/film_update.html.twig',
      array(
        'form_film' => $forms,
      )
    );
}

类型电影

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name', TextType::class)
        ->add('style', TextType::class)
        ->add('director', TextType::class)
        ->add('actor', TextType::class)
    ;
}

/**

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'LfayBundle\Entity\Film\Film'
    ));
}

我找到了!!!!

如果有人需要解决同样的问题，这是我的解决方案。

FilmController：

   /**
     * @Route("/film/update", name="film_update")
     */
    public function updateAction(Request $request)
    {

        $films = array('films' => $this->getDoctrine()->getRepository('LfayBundle:Film\Film')->findAll()) ;
        $forms = $this->createForm(FilmContainerType::class, $films);

        $forms->handleRequest($request);
        if ($forms->isSubmitted() && $forms->isValid()) {

            $em = $this->getDoctrine()->getManager();
            //$em->persist($films_all);
            $em->flush();

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

        return $this->render(
          'film/film_update.html.twig',
          array(
            'forms' => $forms->createView(),
          )
        );
    }

FilmContainerType：

class FilmContainerType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
          ->add('films', CollectionType::class, array(
          'entry_type' => FilmType::class));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
          'data_class' => null
        ));
    }

    public function getName()
    {
        return 'xxxx_bundle_film_container_type';
    }
}

FilmType：

class FilmType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
          ->add('style', TextType::class)
          ->add('director', TextType::class)
          ->add('actor', TextType::class)
        ;
    }

    /**
     * @param OptionsResolver $resolver
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'xxxxBundle\Entity\Film\Film'
        ));
    }
}
