[英]Symfony3 multiple upload files
我实现了一个用于在目录中上传文件的表单。 我会使用没有 manytomany 关系的多个插入。
这是我的实体文档:
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\HttpFoundation\File\UploadedFile;
/**
* @ORM\Entity
*/
class Document
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
public $id;
/**
* @Assert\File(maxSize="6000000")
*/
private $file;
/**
* @ORM\Column(type="string", length=255)
* @Assert\NotBlank
*/
public $name;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
public $path;
public function getAbsolutePath()
{
return null === $this->path
? null
: $this->getUploadRootDir().'/'.$this->path;
}
public function getWebPath()
{
return null === $this->path
? null
: $this->getUploadDir().'/'.$this->path;
}
protected function getUploadRootDir()
{
// the absolute directory path where uploaded
// documents should be saved
return __DIR__.'/../../../web/'.$this->getUploadDir();
}
protected function getUploadDir()
{
// get rid of the __DIR__ so it doesn't screw up
// when displaying uploaded doc/image in the view.
return 'uploads/documents';
}
/**
* Sets file.
*
* @param UploadedFile $file
*/
public function setFile(UploadedFile $file = null)
{
$this->file = $file;
}
/**
* Get file.
*
* @return UploadedFile
*/
public function getFile()
{
return $this->file;
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
*
* @return Document
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set path
*
* @param string $path
*
* @return Document
*/
public function setPath($path)
{
$this->path = $path;
return $this;
}
/**
* Get path
*
* @return string
*/
public function getPath()
{
return $this->path;
}
public function upload() {
// the file property can be empty if the field is not required
if (null === $this->getFile()) {
return;
}
// use the original file name here but you should
// sanitize it at least to avoid any security issues
// move takes the target directory and then the
// target filename to move to
$this->getFile()->move(
$this->getUploadRootDir(), $this->getFile()->getClientOriginalName()
);
// set the path property to the filename where you've saved the file
$this->path = $this->getUploadRootDir()."/".$this->getFile()->getClientOriginalName();
// clean up the file property as you won't need it anymore
$this->file = null;
}
}
这是我的控制器:
public function uploadAction(Request $request) {
$document = new Document();
$form = $this->createFormBuilder($document)
->add('name')
->add('file',FileType::class,array(
"attr" => array(
"accept" => "image/*",
"multiple" => "multiple",
)
))
->add('save', SubmitType::class, array(
'label' => 'Salva',
'attr' => array('class' => 'btn btn-primary')
))
->getForm();
$form->handleRequest($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$document->upload();
$em->persist($document);
$em->flush();
return $this->redirectToRoute('immovable_upload');
}
return $this->render('AppBundle:Immovable:upload.html.twig', array(
'form' => $form->createView(),
));
}
如何编辑我的代码以插入更多图像? 有一个表单的转发器就足够了,这样它只能进行多次插入??
我认为您可以尝试嵌入一组表单,如http://symfony.com/doc/current/cookbook/form/form_collections.html 所述。
你也可以使用特定的 bundle https://github.com/glavweb/GlavwebUploaderBundle来完成你的任务。
