Question

我有一些具有CollectionType的嵌套表单，并且似乎来自构造函数的数据没有传递到第二个嵌套级别。

我简化了表单类，只是我认为这很重要（如果您想获得更多信息，请在评论中告诉我）。

完全根据 Activity 实体类生成底层表单：

class ActivityServiceCreationType extends AbstractType {
  public function buildForm(FormBuilderInterface $builder, array $options) {

    $builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event) use ($options, $router) {
      $activity = $event->getData();
      dump($activity); //JUST TO TEST

      $form = $event->getForm();
      ... //$form->add of all necessary fields
    }
  }

  public function configureOptions(OptionsResolver $resolver) {
    $resolver->setDefaults(array(
      'data_class' => 'AppBundle\Entity\Activity',
      ...
    );
  }
}

在ActivityServiceCreationType上，我具有下一个表单，该表单只是前一个表单的集合：

class ActivityServiceCreationMultipleType extends AbstractType {

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

    $builder
      ->add('activities', CustomCollectionType::class, [
        'entry_type'    => ActivityServiceCreationType::class,
        'entry_options' => $options,
        'mapped'        => true,
        'allow_add'     => true,
        'show_add_link' => true,
      ])
    ;

    $builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event) use ($options) {
      $data = $event->getData();
      dump($data); //To test the data arriving to this form

    });
  }

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

然后我有了“主”表单，可以从控制器创建它：

class ActivityServiceCreationCollectionType extends AbstractType {
  public function buildForm(FormBuilderInterface $builder, array $options) {
  $builder
    ->add('selectAll', CheckboxType::class, [...])
    ...
  ;

  $builder->add('multipleActivities', CustomCollectionType::class, [
    'entry_type'    => ActivityServiceCreationMultipleType::class,
    'entry_options' => [
      "router"     => $options["router"],
      "em"         => $options['em'],
      "basePeriod" => $options['basePeriod'],
      'fit'        => $options['fit'],
      'periods'    => $options['periods'],
      'activities' => $options['activities']
    ],
    'mapped'        => true
    ])
  ;
}

我想从控制器中将Activity对象设置为ActivityServiceCreationType表单，以便可以创建字段。我正在这样做：

$form = $this->createForm(ActivityServiceCreationCollectionType::class,
  ["multipleActivities" => ["activities" => $activities]],
  [
    "router"     => $this->get("router"),
    "em"         => $this->getEm(),
    "periods"    => $periods,
    "basePeriod" => $basePeriod,
    'fit'        => $fit
  ]);

您会看到表格的数据是：

["multipleActivities" => ["activities" => $activities]]

我在代码中放入的转储结果如下：对于第一个转储，在ActivityServiceCreationMultipleType中，我获得一个Activity的ArrayCollection

是女巫，这没问题，

但是在第二个转储中，在ActivityServiceCreationType中，我得到空。在这里，我期望的是集合中每个表单的一个Activity实体，对吧？

你能告诉我我哪里错了吗？

- 编辑以添加更多信息：我一直想知道何时数据“丢失”，并在集合类型中向事件添加了一些代码。在ActivityServiceCreationMultipleType中，以这种方式更改了POST_SET_DATA：

$builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event) use ($options) {
  $data = $event->getData();
  dump($data);

  $form = $event->getForm();
  $form->get('activities')->setData($data);
});

现在，ActivityServiceCreationMultipleType（您在上一个代码片段中看到的）中的dump（）显示了活动数组。直接活动。并且ActivityServiceCreationType中的dump（）被执行36次（每个活动一个），并且为null。不知道为什么它似乎将数据传递给最后的嵌入式表单，但是该事件无法获取它。

ActivityServiceCreationCollectionType的configurateOptions必须为：

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

ActivityServiceCreationMultipleType的configureOptions。

public function configureOptions(OptionsResolver $resolver) {
    $resolver->setDefaults(array(
      'data_class' => null,
      'entry_options' => null,
      'router" => null,
      'em" => null,
      'basePeriod" => null,
      'fit' => null,
      'periods'=>null,
      'activities' => null
    ));
  }

ActivityServiceCreationType的configureOptions。

public function configureOptions(OptionsResolver $resolver) {
    $resolver->setDefaults(array(
      'data_class' => 'AppBundle\Entity\Activity',
      'entry_options' => null,
      'router" => null,
      'em" => null,
      'basePeriod" => null,
      'fit' => null,
      'periods'=>null,
      'activities' => null
    ));
  }

最后，您必须始终在configureOptions中指示要传递给表单的每个外部属性

Symfony3将表单数据传递给集合中的集合
