Php Symfony 3-CollectionType仅保存第一个元素

我有一个很奇怪的问题。我有一个实体：财产 它与图片有着多方面的联系

当我为表单添加更多图片时，当我只保存第一张已保存的图片时，其余的则不保存。 但是，我可以在每次保存后添加新图片，但一次只能添加一张

表格：

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

            // Pictures
            ->add('propertyImages', CollectionType::class, array(
                'by_reference' => false,
                'entry_type' => PropertyImageType::class,
                'allow_add'    => true,
                'allow_delete' => true,
            ))
            ->add('propertyPlans', CollectionType::class, array(
                'by_reference' => false,
                'entry_type' => PropertyPlanType::class,
                'allow_add'    => true,
                'allow_delete' => true,
            ))

            ...
        ;
        $builder->add('save', ButtonType::class, array(
            'label' => 'property.form.save'
        ));
    }



    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Ciber\PropertyBundle\Entity\Property',
        ));
    }
}

有趣的事实：

if ($request->isMethod('POST')) {
        $form->handleRequest($request);
        $property = $form->getData();
        dump($property); exit();
...

当我转储$property时-在同时提交两张图片之后-我得到了以下结果：

elements: array:2 [▼
0 => PropertyImage {#3937 ▼
  -id: 10
  -isDefault: false
  -title: null
  -property: Property {#2799}
  -imageFile: null
  -imageName: "5939c65692d47.jpg"
  #createdAt: DateTime {#3933 ▶}
  #updatedAt: DateTime {#2605 ▶}
}
1 => PropertyImage {#4225 ▼
  -id: null
  -isDefault: false
  -title: null
  -property: Property {#2799}
  -imageFile: UploadedFile {#14 ▶}
  -imageName: null
  #createdAt: null
  #updatedAt: DateTime {#4224 ▶}
}
]

我真的不知道这里发生了什么 （当然，我有更多的字段，比如title，我认为这与问题无关。但是，正如您所看到的，我还有一个“PropertyPlans ArrayCollection，它也有同样的问题。只有第一个字段正确地存在）

编辑。这是我的控制器：

/**
 * @Route("/properties/{property_category}/new", name="propertycreateindex")
 */
public function propertyCreateIndexAction(Request $request)
{

    $entity = new Property();
    $form = $this->createForm(Ciber\PropertyBundle\Form\FlatType, $entity);

    if ($request->isMethod('POST')) {
        $form->handleRequest($request);
        $property = $form->getData();
        $property->setUser($this->getUser());
        $property->setIsActive(1);
        $em = $this->getDoctrine()->getManager();
        $em->persist($property);
        $em->flush();
        $this->addFlash(
            'success',
            $this->get('translator')->trans('success.message.create_successfull')
        );
        return $this->redirectToRoute('dashboard');
    }

    return $this->render(view.html.twig, array(
        'form' => $form->createView(),
        'property' => $entity
    ));

}

这是PropertyImageType.php

namespace Ciber\PropertyBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Vich\UploaderBundle\Form\Type\VichImageType;

class PropertyImageType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('isDefault')
            ->add('title', TextType::class, array(
                'required' => false
            ))
            ->add('imageFile', VichImageType::class, array(
                'required' => false,
                'allow_delete' => true, // not mandatory, default is true
                'download_link' => false //  default is true
            ));

    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Ciber\PropertyBundle\Entity\PropertyImage',
        ));
    }
}

对不起，我的不好。我睡了几个小时后，重新测试了一下。 我发现，我错了。不是第一张，而是最后一张。 从这里，这是一个简单的方法来找出，我错过了一行从教程

newinputs.each(function(){
    $(this).attr('id', $(this).attr('id').replace(/__name__/g, $randomId));
    $(this).attr('name', $(this).attr('name').replace(/__name__/g, $randomId));
});

CollectionType默认的“property_name”是name，在从form.prototype创建新的嵌入后，必须使用javascript对其进行修改

你必须在新创建的字段中更改名称。

控制器、命令或其他什么东西在哪里被持久化？在转储中很奇怪，它显示第一个实体已经存在，但第二个是一个

上传文件

。这个编辑和图像已经存在吗？我已经更新了帖子。不，两个图像都是newly uploaded。第二个在UploadedFile节点上有第二个图像数据。并且您没有使用浏览器中的其他工具预上载它们？您不认为这很奇怪，第一个保存，第二个（仅显示为UploadedFile）没有保存？我想看看为什么会这样。在这种情况下，第一个也应该显示为已上载。在任何情况下，您可能应该在上载时迭代该集合中的

属性图像

，处理文件本身，然后在保存之前保存并更新实体。我没有看到任何特定的代码lly将一个

UploadedFile

转换为可以像第一行一样持久化的内容。作为symfony文档：通过这两个更改，在提交表单时，通过调用addTag（）方法将每个新标记对象添加到Task类中。在此更改之前，表单通过调用$Task->getTags（）->add在内部添加它们（$tag）。这很好，但是强制使用“adder”方法可以更容易地处理这些新的标记对象。
