symfony - "Multiple Upload"与 Symfony 3 上的 VichUploaderBundle

Question

我尝试使用 bundle VichUploader 允许多次上传。在这个项目中，我有一个类(class)剧院，它拥有一个主图像，但也有一些次要图像(图像集合)。实际上每一个副图都是一个资源。所以一个剧院有一个多资源，一个资源连接到一个剧院。

但是当我尝试创建时，我可以访问我的表单，但是当我尝试保存时出现错误:

Expected argument of type "AppBundle\Entity\Resources", "AppBundle\Entity\Theatre" given 

这是我的类(class)剧院，只有多次上传的详细信息:

namespace AppBundle\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
use Vich\UploaderBundle\Mapping\Annotation as Vich;

/**
* Theatre
*
* @ORM\Table(name="theatre")
* @ORM\Entity
* @Vich\Uploadable
*/
class Theatre
{

/**
 *  @var ArrayCollection
 * @ORM\OneToMany(targetEntity="Resources", mappedBy="theatre", cascade={"persist", "remove"}, orphanRemoval=true)
 */
private $images;

// ..

/**
 * Constructor
 */
public function __construct()
{
    $this->images = new \Doctrine\Common\Collections\ArrayCollection();
}

// MultiUpload
/**
 * @return ArrayCollection
 */
public function getImages()
{
    return $this->images;
}

/**
 * @param ArrayCollection $pictures
 */
public function setImages($pictures)
{
    $this->images = $pictures;
}

public function getAttachImages()
{
    return null;
}

/**
 * @param array $files
 *
 * @return array
 */
public function setAttachImages(array $files=array())
{
    if (!$files) return [];
    foreach ($files as $file) {
        if (!$file) return [];
        $this->attachImages($file);
    }
    return [];
}

/**
 * @param UploadedFile|null $file
 */
public function attachImages(UploadedFile $file=null)
{
    if (!$file) {
        return;
    }
    $picture = new Resources();
    $picture->setImage($file);
    $this->addImage($picture);
}



/**
 * Add image.
 *
 * @param \AppBundle\Entity\Resources $image
 *
 *
 */
public function addImage(\AppBundle\Entity\Resources $image)
{
    $image->setTheatre($this);
    //$this->images->add($image);
    $this->images[] = $image;

    //return $this;
}

/**
 * Remove image.
 *
 * @param \AppBundle\Entity\Resources $image
 *
 *
 */
public function removeImage(\AppBundle\Entity\Resources $image)
{
    $image->setTheatre(null);
    $this->images->removeElement($image);
   // return $this->images->removeElement($image);
}

然后是我的类资源:

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\Context\ExecutionContextInterface;
use Vich\UploaderBundle\Mapping\Annotation as Vich;

/**
* Resources
*
* @ORM\Table(name="resources")
* @ORM\Entity
* @Vich\Uploadable
*/
class Resources
{

 /**
 * @var Theatre
 * @ORM\ManyToOne(targetEntity="Theatre", inversedBy="images")
 */
private $theatre;

/**
 * @Vich\UploadableField(mapping="uploads_image", fileNameProperty="url")
 * @Assert\File(
 *      mimeTypes = {"image/png", "image/jpeg", "image/jpg"},
 *      mimeTypesMessage = "Please upload a valid valid IMAGE"
 * )
 *
 *
 * @var File $image
 */
protected $image;

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


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

public function getImage()
{
    return $this->image;
}

// ..

  /**
 * Set theatre.
 *
 * @param \AppBundle\Entity\Theatre $theatre
 *
 * @return Resources
 */
public function setTheatre(\AppBundle\Entity\Theatre $theatre)
{
    $this->theatre = $theatre;

    return $this;
}

/**
 * Get theatre.
 *
 * @return \AppBundle\Entity\Theatre
 */
public function getTheatre()
{
    return $this->theatre;
}

/**
 * Set url.
 *
 * @param string $url
 *
 * @return Resources
 */
public function setUrl($url)
{
    $this->url = $url;

    return $this;
}

/**
 * Get url.
 *
 * @return array
 */
public function getUrl()
{
    return $this->url;
}

然后我添加到构建器中:

namespace AppBundle\Form\Collection;

use AppBundle\Entity\Theatre;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\FileType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Vich\UploaderBundle\Form\Type\VichFileType;


class TheatreImages extends AbstractType{
/**
 * @param FormBuilderInterface $builder
 * @param array                $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('attachImages', FileType::class, ['multiple'=>true, 'required'=>false])
    ;


}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => Theatre::class,
    ));
}

/**
 * @return string
 */
public function getName()
{
    return 'app_theatreImages';
}
}

我使用 bundle easyAdminBundle 添加我的配置:

easy_admin:
   entities:
    Theatre:
        class: AppBundle\Entity\Theatre
        list:
            title: 'Liste des théâtres'
            fields:
                - 'Name'
                - 'adress'
                - 'Metro station'
                - { property: 'Main image', type: 'image',  template: 'theatreFile.html.twig',  base_path: '%app.path.theatre_images%' }

        new:
            title: 'Création théâtre'
            fields:
                - { type: 'section', label: 'Information du théâtre' }
                - {property: 'name', label: 'Nom'}
                - {property: 'number_of_seats', type: 'integer', label: 'Nombre de sièges'}
                - {property: 'about', label: 'description'}
                - { property: 'imageFile', type: 'vich_file', label: 'image', type_options: { required: false}}
                - {property: 'images', type: 'collection', type_options: {entry_type: 'AppBundle\Form\Collection\TheatreImages', by_reference: false}}
                - { type: 'section', label: 'Localisation du théâtre' }
                - {property: 'adress', label: 'adresse'}
                - {property: 'metro_station', label: 'Station de métro'}
                - {property: 'location_coordinates', label: 'Coordonnées'}
        edit:
            title: "Édition théâtre"
            fields:
                - { type: 'section', label: 'Information du théâtre' }
                - {property: 'name', label: 'Nom'}
                - {property: 'number_of_seats', type: 'integer', label: 'Nombre de sièges'}
                - {property: 'about', label: 'description'}
                - { property: 'imageFile', type: 'vich_file', label: 'image', type_options: { required: false}}
                - {property: 'images', type: 'collection', type_options: {entry_type: 'AppBundle\Form\Collection\TheatreImages', by_reference: false}}
                - { type: 'section', label: 'Localisation du théâtre' }
                - {property: 'adress', label: 'adresse'}
                - {property: 'metro_station', label: 'Station de métro'}
                - {property: 'location_coordinates', label: 'Coordonnées'}

提前致谢。

Answer 1

我已经为一个非常有用的包 [VichUploader] 创建了一个解决方案，它缺少多次上传的功能，并且它适用于我在 [Symfony] 5.2 上创建的每个 Symfony 版本。它在 OneToMany 关系上并且工作正常。所以我在我的自定义表单中使用了 CollectionType 和 [VichFileType] 并在我的 Controller 中使用了一些小技巧，这里是代码并查看所有项目，你可以在我的 GitHub 中找到它[链接] https://github.com/malek-laatiri

Admission.php

class Admission
{
    /**
     * @ORM\OneToMany(targetEntity=Diplome::class, mappedBy="admission")
     */
    private $diplomes;
    /**
     * @return Collection|Diplome[]
     */
    public function getDiplomes(): Collection
    {
        return $this->diplomes;
    }

    public function addDiplome(Diplome $diplome): self
    {
        if (!$this->diplomes->contains($diplome)) {
            $this->diplomes[] = $diplome;
            $diplome->setAdmission($this);
        }

        return $this;
    }

    public function removeDiplome(Diplome $diplome): self
    {
        if ($this->diplomes->removeElement($diplome)) {
            // set the owning side to null (unless already changed)
            if ($diplome->getAdmission() === $this) {
                $diplome->setAdmission(null);
