Question

我有一个问题，即替换上传文件的形式错误。

实体：

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;

/**
 * Class Document
 *
 * @package    Cfw\SiteBundle\Entity
 * @ORM\Entity(repositoryClass="Cfw\SiteBundle\Entity\Repository\Document\DocumentRepository")
 * @ORM\HasLifecycleCallbacks
 * @ORM\Table
 */

class Document
{
    use IdentityEntity;

    use TimestampableEntity;

    CONST UPLOAD_LIMIT = 10;

    /**
     * Document path
     * @var string
     *
     * @ORM\Column(type="text", length=255, nullable=false)
     */
    protected $path;

    /**
     * @var string
     *
     * @ORM\Column(type="text", length=50, nullable=false)
     */
    protected $type;

    /**
     * @var string
     *
     * @ORM\Column(type="text", length=255, nullable=false)
     */
    protected $name;

    /**
     * Image file
     *
     * @var File
     *
     */
    protected $file;
    ....
}

表格类型：

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\DependencyInjection\ContainerInterface;

class DocumentType extends AbstractType
{
    /**
     * @var ContainerInterface $container
     */
    protected $container;

    /**
     * DocumentType constructor.
     * @param ContainerInterface $container
     */
    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add(
            'file',
            null,
            [
                'required' => false,
                'attr' => [
                    'label' => false,
                    'title' =>  'form.document.browse',
                ],
                'validation_groups' => ['Default', 'Document'],
            ]
        );
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(
            [
                'error_bubbling' => true,
                'data_class' => 'Cfw\SiteBundle\Entity\Document\Document',
                'translation_domain' => 'messages',
                'cascade_validation' => true,
                'validation_groups' =>  ['Default', 'Document'],
            ]
        );
    }

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

控制器：

public function documentAction(Request $request)
{
    /**
     * @var $user \Cfw\UserBundle\Entity\User
     */
    $user = $this->getUser();
    if (!is_object($user) || !$user instanceof UserInterface) {
        throw new AccessDeniedException('This user does not have access to this section.');
    }

    $form = $this->createForm('cfw_document');

    $form->handleRequest($request);

    if ($form->isValid()) {
        $this->get('cfw.document')->uploadDocument($form->getData(), $user);
    }

    return $this->render(
        'CfwUserBundle:Profile:document.html.twig',
        [
            'form' => $form->createView(),
            'documents' => $this->get('cfw.document')->getUserDocuments($user),
            'upload_limit' => $this->get('cfw.document')->getUploadLimit(),
        ]
    );
}

查看：

{{ form_start(form) }}
<div class="col-lg-8 document-form">
    <div class="row form-message">
        {{ form_errors(form) }}
    </div>
    <div class="row">
        <h3>{{ 'form.document.title'|trans }}</h3>
    </div>
    <div class="row">
        <div class="col-lg-12 col-md-12">
            {{ 'form.document.description'|trans }}
        </div>
    </div>
    <div class="row top10">
        <div class="col-lg-6 col-md-6">
            {{ form_widget(form.file) }}
        </div>
        <div class="col-lg-6 col-md-6">
            {{ 'form.document.allowed_types'|trans }}<br />
            <span class="allowed-size">{{ 'form.document.allowed_size'|trans }}</span>
        </div>
    </div>

    <div class="row">
        <div class="col-md-4 col-lg-4 submit-block">
            <button type="submit" class="btn btn-warning btn-block">{{ 'form.document.submit'|trans }}</button>
        </div>
    </div>
</div>
{{ form_end(form) }}

验证配置为：

Cfw\SiteBundle\Entity\Document\Document:
    properties:
        file:
            - File:
                maxSize: "10M"
                mimeTypes: ["image/jpeg", "image/gif", "image/png", "image/tiff", "application/pdf"]
                maxSizeMessage: document.file.wrong_size
                mimeTypesMessage: document.file.wrong_format
                groups: [Default, Document]

麻烦的是，如果我上传zip文件需要显示错误类型的错误。但是，没有显示任何内容，也没有上传文件（当pdf或图像正常时）。

如果显示更改{{form_errors（form.file）}}错误，但我认为不正确。在字段文件中显示的分析器错误中，但$ form-＆gt; getErrors（）为空。

有人可以说出了什么问题吗？

Answer 1

我在DocumentType中遇到错误。需要添加

'error_bubbling' => true

到字段“file”，而不是setDefaults（）

Symfony2文件上传表单不显示错误
