image_name 在数据库中始终为空 vichuploaderbundle symfony2

Question

我正在尝试使用图像文件添加新用户。我正在使用 VichUpladerBundle and FOSUserBundle。因此创建了新用户，但 image_name 始终为空。

这是我的图像实体：

namespace SocialNetworkBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Gedmo\Mapping\Annotation as Gedmo;
use Vich\UploaderBundle\Mapping\Annotation as Vich;

    /**

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

    /**
     * Get id
     *
     * @return int
     */
    public function getId() {
        return $this->id;
    }

    /**
     * NOTE: This is not a mapped field of entity metadata, just a simple property.
     * 
     * @Vich\UploadableField(mapping="image", fileNameProperty="imageName")
     * @Assert\File(
     *     maxSize = "1024k",
     *     mimeTypes = {"image/png", "image/jpeg", "image/jpg"},
     *     mimeTypesMessage = "Please upload a valid PDF or valid IMAGE"
     * )
     * 
     * @var File
     */
    private $imageFile;

    /**
     * @ORM\Column(type="string", length=255, nullable=true)
     *
     * @var string
     */
    private $imageName;

    /**
     * @ORM\Column(type="datetime")
     *
     * @var \DateTime
     */
    private $updatedAt;

    /**
     * Set imageName
     *
     * @param string $imageName
     *
     * @return Image
     */
    public function setImageName($imageName) {
        $this->imageName = $imageName;

        return $this;
    }

    /**
     * Get imageName
     *
     * @return string
     */
    public function getImageName() {
        return $this->imageName;
    }

    /**
     * @param File|\Symfony\Component\HttpFoundation\File\UploadedFile $image
     *
     * @return Image
     */
    public function setImageFile(File $image = null) {
        $this->imageFile = $image;

        if ($image) {
            $this->updatedAt = new \DateTime('now');
        }

        return $this;
    }

    /**
     * @return File|null
     */
    public function getImageFile() {
        return $this->imageFile;
    }

}

用户实体：

namespace UserBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\Common\Collections\ArrayCollection;

    private $image;

    /**

     */
    public function setName($name) 
    {
        $this->name = $name;

    }

    /**

    }

    /**

    public function setImage(\SocialNetworkBundle\Entity\Image $image = null) 
    {
        $this->image = $image;

        return $this;
    }

    /**

     * @return \SocialNetworkBundle\Entity\Image
     */
    public function getImage() 
    {
        return $this->image;
    }
}

图片类型：

namespace SocialNetworkBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Vich\UploaderBundle\Form\Type\VichFileType;

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

    ;
  }

  public function setDefaultOptions(OptionsResolverInterface $resolver)

        'data_class' => 'SocialNetworkBundle\Entity\Image',
    ));
  }

  public function getName()
  {

}

注册表单：

namespace UserBundle\Form\Type;

use Symfony\Component\Form\FormBuilderInterface;
use FOS\UserBundle\Form\Type\RegistrationFormType as BaseType;
use SocialNetworkBundle\Form\ImageType;

class RegistrationFormType extends BaseType

    {
        parent::buildForm($builder, $options);

        // add your custom field
        $builder->add('name')
            ->add('roles', 'collection', array(

Answer 1

您应该将一个映射字段（例如，updatedAt）添加到您的图像实体中。当您使用方法 setImageFile 设置图像时，您还应该更新映射字段以触发原则事件侦听器并处理上传的文件。

    public function setImageFile(File $image = null) 
    {
        $this->imageFile = $image;

        if ($image) {
            $this->updatedAt = new \DateTime('now');
        }
