    }
}

Symfony 4 working solution.

Quite more simple. Just tidy your entities, create form and form transformer

// src/Entity/Product.php
 /**
 * @ORM\Entity
 * @Vich\Uploadable
 */
class Product
{
    ...

    /**
     * @var Collection|ProductPicture[]
     * @ORM\OneToMany(targetEntity="AppBundle\Entity\ProductPicture", mappedBy="product", cascade={"persist", "remove"}, orphanRemoval=true)
     */
    private $pictures;

    public function __construct()
    {
        $this->pictures = new ArrayCollection();
    }

    /**
     * @return Collection|ProductPicture[]
     */
    public function getPictures(): Collection
    {
        return $this->pictures;
    }

    public function addPicture(ProductPicture $picture): self
    {
        if (!$this->pictures->contains($picture) {
            $this->pictures->add($picture);
            $picture->setProduct($this);
        }

        return $this;
    }

    public function removePicture(ProductPicture $picture): self
    {
        if ($this->pictures->contains($picture) {
            $this->pictures->removeElement($picture);
            if ($picture->getProduct() === $this) {
                $picture->setProduct(null);
            }
        }

        return $this;
    }

    ...
}

// src/Entity/ProductPicture.php
/**
 * @ORM\Entity
 * @Vich\Uploadable
 */
class ProductPicture
{
    ...

    /**
     * @var Product
     * @ORM\ManyToOne(targetEntity="AppBundle\Entity\Product", inversedBy="pictures")
     * @ORM\JoinColumn(nullable=false)
     */
    private $product;

    /**
     *
     * @Vich\UploadableField(mapping="product_image", fileNameProperty="imageName", size="imageSize")
     * @Assert\File(
     *     maxSize = "1024k",
     *     mimeTypes = {"image/png", "image/jpeg", "image/jpg"},
     *     mimeTypesMessage = "Please upload a valid valid IMAGE"
     * )
     *
     * @var File
     */
    private $imageFile;

    ...

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

        if (null !== $image) {
            // It is required that at least one field changes if you are using doctrine
            // otherwise the event listeners won't be called and the file is lost
            $this->updatedAt = new DateTimeImmutable();
        }
    }

    public function getImageFile()
    {
        return $this->imageFile;
    }

    public function setProduct(Product $product)
    {
        $this->product = $product;
    }

    public function getProduct()
    {
        return $this->product;
    }

    ...
}

Then you need to create simple ProductType form:

// src/Form/ProductForm.php
class PictureType extends AbstractType
{

    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add($builder->create(
                'pictures',
                FileType::class,
                [
                    'required' => false,
                    'multiple' => true,
                ]
            )->addModelTransformer(new FilesToPicturesTransformer()))
            ->add(...);
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => Product::class,
        ]);
    }

and FilesToPicturesTransformer (data transformer):

// src/Form/FilesToPicturesTransformer.php
class FilesToPicturesTransformer implements DataTransformerInterface
{
    /**
     * {@inheritdoc}
     */
    public function transform($value): void
    {
        // don't need this if you build API
    }

    /**
     * {@inheritdoc}
     */
    public function reverseTransform($value): ArrayCollection
    {
        $pictures = new ArrayCollection();

        foreach ($value as $file) {
            $picture = (new ProductPicture())
                ->setImageFile($file);
            if (!$pictures->contains($picture)) {
                $pictures->add($picture);
            }
        }

        return $pictures;
    }
}

You should build the file part as an entity

/**
 * @ORM\Entity
 * @Vich\Uploadable
 */
class ProductPicture
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var Product
     * @ORM\ManyToOne(targetEntity="path\to\your\entity\Product", inversedBy="pictures")
     */
    private $product;

    /**
     *
     * @Vich\UploadableField(mapping="product_image", fileNameProperty="imageName", size="imageSize")
     * @Assert\File(
     *     maxSize = "1024k",
     *     mimeTypes = {"image/png", "image/jpeg", "image/jpg"},
     *     mimeTypesMessage = "Please upload a valid valid IMAGE"
     * )
     *
     * @var File
     */
    private $imageFile;

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

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

    public function getImageFile()
    {
         return $this->imageFile;
    }

    public function setProduct(Product $product)
    {
        $this->product = $product;
    }

    public function getProduct()
    {
         return $this->product;
    } 
}

And in your Product entity...

    /**
     * @var ArrayCollection
     * @ORM\OneToMany(targetEntity="path\to\your\entity\ProductPicture", mappedBy="product", cascade={"all"}, orphanRemoval=true)
     */
    private $pictures;

    public function __construct()
    {
        $this->pictures = new ArrayCollection();
    }

    /**
     * @return ArrayCollection
     */
    public function getPictures()
    {
        return $this->pictures;
    }

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

    public function getAttachPictures()
    {
        return null;
    }

    public function setAttachPictures(array $files=array())
    {
        if (!$files) return [];
        foreach ($files as $file) {
            if (!$file) return [];
            $this->attachPicture($file);
        }
        return [];
    }

    public function attachPicture(UploadedFile $file=null)
    {
        if (!$file) {
            return;
        }
        $picture = new ProductPicture();
        $picture->setImageFile($file);
        $this->addPicture($picture);
    }

    public function addPicture(ProductPicture $picture)
    {
        $picture->setProduct($this);
        $this->pictures->add($picture);
    }

    public function removePicture(ProductPicture $picture)
    {
       $picture->setProduct(null);
       $this->pictures->removeElement($picture);
   }

And finally in the form use...

->add('attachPictures', FileType::class, ['multiple'=>true, 'required'=>false])

Catchable Fatal Error: Argument 1 passed to AppBundle\Entity\Product::attachPicture() must be an instance of AppBundle\Entity\UploadedFile, instance of Symfony\Component\HttpFoundation\File\UploadedFile given

Jakub Staněk Over a year ago

Actually i fixed this eror, but i am getting Error 500

Enumus Over a year ago

Check that in top of the Product entity the use you have is not use AppBundle\Entity\UploadedFile, it must be use Symfony\Component\HttpFoundation\File\UploadedFile

Enumus Over a year ago

Can you provide the trace error of the symfony toolbar?

Enumus Over a year ago

It looks like a form problem... try changing ->add('attachPictures', 'file', ['multiple'=>true, 'required'=>false]) for ->add('attachPictures', FileType::class, ['multiple'=>true, 'required'=>false]) or ->add('attachPictures', VichFileType::class, ['multiple'=>true, 'required'=>false])

I can't help you with this upload bundle, but i can show you how it's working in my case in more simple way (using simple requests, not some fancy bundle)

here https://gist.github.com/poznet/e3955a48fea01d8640dafbd966c53a83

you have

form in view
controller code
trait that is imported in service entity

This trait it's a little mess (no attachemt size/type check etc ) , but it works.

If you have any questions fell free to ask.

PS in your case if you uploading multiple files you get array , not file class :D
