我对 VichUploaderBundle 有问题，我按照所有说明进行操作，但我不知道我的控制器在完成表单后应该如何处理这个问题，因为图像上传失败并且数据库没有写入。
我的实体类：
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\HttpFoundation\File\File;
use Vich\UploaderBundle\Mapping\Annotation as Vich;
use Symfony\Component\HttpFoundation\File\UploadedFile;
/**
* @ORM\Entity
* @Vich\Uploadable
*/
class Product
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
// ..... other fields
/**
* NOTE: This is not a mapped field of entity metadata, just a simple property.
*
* @Vich\UploadableField(mapping="product_image", fileNameProperty="imageName", size="imageSize")
*
* @var File
*/
private $imageFile;
/**
* @ORM\Column(type="string", length=255)
*
* @var string
*/
private $imageName;
/**
* @ORM\Column(type="integer")
*
* @var integer
*/
private $imageSize;
/**
* @ORM\Column(type="datetime")
*
* @var \DateTime
*/
private $updatedAt;
/**
* If manually uploading a file (i.e. not using Symfony Form) ensure an instance
* of 'UploadedFile' is injected into this setter to trigger the update. If this
* bundle's configuration parameter 'inject_on_load' is set to 'true' this setter
* must be able to accept an instance of 'File' as the bundle will inject one here
* during Doctrine hydration.
*
* @param File|\Symfony\Component\HttpFoundation\File\UploadedFile $image
*
* @return Product
*/
public function setImageFile(File $image = null)
{
$this->imageFile = $image;
if ($image) {
var_dump($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();
}
return $this;
}
/**
* @return File|null
*/
public function getImageFile()
{
return $this->imageFile;
}
/**
* @param string $imageName
*
* @return Product
*/
public function setImageName($imageName)
{
$this->imageName = $imageName;
return $this;
}
/**
* @return string|null
*/
public function getImageName()
{
return $this->imageName;
}
/**
* @param integer $imageSize
*
* @return Product
*/
public function setImageSize($imageSize)
{
$this->imagesize = $imageSize;
return $this;
}
/**
* @return integer|null
*/
public function getImageSize()
{
return $this->imageSize;
}
}
我的 FormType 类：
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\FileType;
class AvatarType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('imageFile', FileType::class, array('label' => 'Brochure (PDF file)'))
;
}
public function getName()
{
return 'avatar_form';
}
}
配置：
vich_uploader:
db_driver: orm # or mongodb or propel or phpcr
mappings:
product_image:
uri_prefix: /image/avatar
upload_destination: '%kernel.root_dir%/../web/image/avatar'
树枝模板：
<div>
{{ form_start(form) }}
{{ form_label(form) }}
{{ form_errors(form) }}
{{ form_widget(form.imageFile) }}
<button type="submit" class="btn btn-default">Submit</button>
{{ form_end(form) }}
</div>
最后是控制器：
namespace AppBundle\Controller\User;
use AppBundle\Entity\Product;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Session\Session;
use AppBundle\Controller\InitController;
use AppBundle\Form\AvatarType;
class UserController extends Controller implements InitController
{
/**
* @Route("/user/avatar", name="AvatarAction")
*/
public function AvatarAction(Request $request)
{
$form = $this->createForm('AppBundle\Form\AvatarType',null,array(
// To set the action use $this->generateUrl('route_identifier')
'action' => $this->generateUrl('AvatarAction'),
'method' => 'POST'
));
$form->handleRequest($request);
if ($request->isMethod('POST')) {
if($form->isValid()){
//$track = new Product();
//$em = $this->getDoctrine()->getManager();
//$em->persist($track);
//$em->flush();
}
return $this->render('default/avatar.html.twig',array(
'form' => $form->createView()
));
}
}
感谢您的所有建议！
