问题描述
在使用 VichUploaderBundle 上传:
/**
* @Vich\UploadableField(mapping="product_media", fileNameProperty="path")
* @Assert\File(
* mimeTypes = {"image/jpeg", "image/gif", "image/png", "video/mp4", "video/quicktime", "video/avi"},
* mimeTypesMessage = "Wrong file type (jpg,gif,png,mp4,mov,avi)"
* )
* @var File $pathFile
*/
protected $pathFile;
我看不到断言的问题所在.如何使用VichUploader验证文件类型?
I cannot see what the problem is with the assert. How can I validate file types with VichUploader?
推荐答案
您可以使用验证回调来解决此问题.
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()
;
}
}
}
