[Update]: I resolved my problem ><, probably when i have done refactoring i left an ":?string" on my method getFile ...
Today i tried to add VichUploderBundle in my project, but i have encountered some trouble. I have follow the documentation but i don't like the way to make one property uploadable (add 3 properties on the same model just for that, excuse me but that not much pretty) So i started to create an Entity just for Image with all property necessary, I also created a new FormType and link all to my Parent Entity. But now when i try to post my form i get this error :
Return value of Vich\UploaderBundle\Mapping\PropertyMapping::getFile() must be an instance of Symfony\Component\HttpFoundation\File\File or null, string returned
(in vendor/vich/uploader-bundle/Mapping/PropertyMapping.php (line 80) )
I tried to add some dump to check the variable and she exist but for a strange reason Vich detects it as null.
Image Entity
<?php
namespace App\Entity;
use App\Entity\Traits\CreatedAtTrait;
use App\Entity\Traits\CreatedByTrait;
use Doctrine\ORM\Mapping as ORM;
use Exception;
use Symfony\Component\HttpFoundation\File\File;

/**

class Image
{
use CreatedAtTrait;
use CreatedByTrait;
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @Vich\UploadableField(mapping="compose_logo", fileNameProperty="name", size="size")
* @var File
*/
private $file;
/**

private $name;
/**

public function getId(): ?int

return $this->id;
}
public function getFile(): ?string
{
return $this->file;
}

*/
public function setFile(?File $file = null): self
{
$this->file = $file;
return $this;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function getSize(): ?int
{
return $this->size;
}
public function setSize(int $size): self
{
$this->size = $size;
return $this;
}
}
ImageType
<?php
namespace App\Form;
use App\Entity\Image;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Vich\UploaderBundle\Form\Type\VichImageType;
class ImageType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('file', VichImageType::class, [
'required' => false,
])
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Image::class,
]);
}
}
Parent Entity
<?php
namespace App\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity(repositoryClass="App\Repository\ParentRepository")
*/
class Parent
{
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
*/
private $name;
/**
* @ORM\OneToOne(targetEntity="App\Entity\Image", cascade={"persist", "remove"})
*/
private $logo;
public function __construct()
{
$this->variables = new ArrayCollection();
}
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
public function getLogo(): ?Image
{
return $this->logo;
}
public function setLogo(?Image $logo): self
{
$this->logo = $logo;
return $this;
}
}
ParentType
<?php
namespace App\Form;
use App\Entity\Parent;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class ParentType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('logo', ImageType::class)
->add('name', TextType::class)
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Parent::class,
]);
}
}
And for the test i also tried to remove the annotations in vendor/vich/uploader-bundle/Mapping/PropertyMapping.php to accept all variable type and when Doctrine try to save the entity in the database all property in my Image entity is null except my createdAt trait (but that probably normal since i have exception before that ...)
Also there is a screenshot when i dump the variable at line 80 in vendor/vich/uploader-bundle/Mapping/PropertyMapping.php : https://i.stack.imgur.com/MJh2g.jpg
