How to use mimeType Assert with VichUploader?
For Symfony 4.x, this solution not working. i don't know why assert or event validator never call ...
I've find this solution : Validation doesn't work on relation fields
use Symfony\Component\Validator\Constraints\File;
/* ... */
->add('ba_file', VichFileType::class, [
'label' => 'Bon d\'adhésion (PDF file)',
'required' => false,
'constraints' => [
new File([
'maxSize' => '5M',
'mimeTypes' => [
'image/jpeg',
'image/gif',
'image/png',
]
])
]
])
For Symfony 4.0 you'll need to import the Validator component
composer require validator
Now in your Entity class you can use the @Assert annotation.
// src/Entity/Author.php
// ...
use Symfony\Component\Validator\Constraints as Assert;
class Author
{
/**
* @Assert\NotBlank()
*/
public $name;
}
You might need to add some configuration in your config/packages/framework.yaml file. Anyway, all this is perfectly explained on the official Symfony documentation.
http://symfony.com/doc/current/validation.html
To check the mime type you'll need to use the File constraint http://symfony.com/doc/current/reference/constraints/File.html
Here is a working exemple
/**
* @ORM\Column(type="string", length=255)
* @var string
*/
private $cvFilename;
/**
* @Assert\File(
* maxSize = "2048k",
* mimeTypes = {"application/pdf", "application/x-pdf"},
* mimeTypesMessage = "Please upload a valid PDF"
* )
* @Vich\UploadableField(mapping="cv", fileNameProperty="cvFilename")
* @var File
*/
private $cvFile;
Now it's true that there is a mime and size option inside the @Vich\UploadableField anotation as described here https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/usage.md#step-2-link-the-upload-mapping-to-an-entity but I couldn't get this to work.
The @Assert annotation will generate Forms errors, that you can retrieve them in Twig to give a feedback.
The key is to use : form_errors(candidature_form.cvFile)
here is a working example :
{% set error_flag = form_errors(candidature_form.cvFile) %}
<label class=" {% if error_flag %}has-error{% endif %}">
Curriculum Vitae (PDF)
</label>
{{ form_widget(candidature_form.cvFile) }}
{% if error_flag %}
<div class="has-error">
{{ form_errors(candidature_form.cvFile) }}
</div>
{% endif %}
You can use validation callback to solve this issue.
/**
* @ORM\Entity(repositoryClass="AppBundle\Entity\Repository\EntityRepository")
* @ORM\Table(name="entity")
* @Assert\Callback(methods={"validate"})
* @Vich\Uploadable
*/
class Entity
{
/**
* @Assert\File(maxSize="10M")
* @Vich\UploadableField(mapping="files", fileNameProperty="fileName")
*
* @var File $file
*/
protected $file;
/**
* @ORM\Column(type="string", length=255, name="file_name", nullable=true)
*
* @var string $fileName
*/
protected $fileName;
...
/**
* @param ExecutionContextInterface $context
*/
public function validate(ExecutionContextInterface $context)
{
if (! in_array($this->file->getMimeType(), array(
'image/jpeg',
'image/gif',
'image/png',
'video/mp4',
'video/quicktime',
'video/avi',
))) {
$context
->buildViolation('Wrong file type (jpg,gif,png,mp4,mov,avi)')
->atPath('fileName')
->addViolation()
;
}
}
}
For Symfony 3.0+, only 2 things need to be done:
Add use statement to import ExecutionContextInterface.
The callback annotation has to be added directly to the method/function instead of the class.
use Symfony\Component\Validator\Context\ExecutionContextInterface; /** * @Assert\File(maxSize="2M") * @Vich\UploadableField(mapping="profile_image", fileNameProperty="avatar") * @var File */ private $imageFile; /** * @ORM\Column(length=255, nullable=true) * @var string $avatar */ protected $avatar; /** * @Assert\Callback * @param ExecutionContextInterface $context */ public function validate(ExecutionContextInterface $context, $payload) { // do your own validation if (! in_array($this->imageFile->getMimeType(), array( 'image/jpeg', 'image/gif', 'image/png' ))) { $context ->buildViolation('Wrong file type (only jpg,gif,png allowed)') ->atPath('imageFile') ->addViolation(); } }
