Question

我是Symfony的新人。我一直在尝试创建一个可重用的表单并使用它上传图像。问题是图像没有保存在我给出的路径中。我不知道我做错了什么。我真的很感激任何建议。

Answer 1

我正在使用getView().setVisibility(View.GONE)表单和文件上传我不建议按照官方文档中的描述进行操作。请查看https://github.com/dustin10/VichUploaderBundle，配置您的上传，链接实体并享受！

Answer 2

我认为文档是基本文件上传的一个很好的例子。

尝试更新您的实体：

/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
 private $id;

/**
 * @ORM\Column(name="name",type="string",length=255)
 * @Assert\NotBlank
 */
 public $name;

/**
 * @ORM\Column(name="path",type="string",length=255, nullable=true)
 */
 public $path;

/**
 * @Assert\File(maxSize="6000000")
 */
 public $file;

     /**
 * 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 $name
 * @return File
*/
public function setName($name)
{
    $this->name = $name;

    return $this;
}

/**
 * Get name
 *
 * @return string
*/
public function getName()
{
    return $this->name;
}

/**
 * Set path
 *
 * @param string $path
 * @return File
*/
public function setPath($path)
{
    $this->path = $path;

    return $this;
}

/**
 * Get path
 *
 * @return string
 */
public function getPath()
{
    return $this->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;
}

public function getUploadRootDir()
{
    return __DIR__.'/../../../../web/'.$this->getUploadDir();
}

public function getUploadDir()
{
    return 'uploads/documents/';
}

public function upload()
{
    if (null === $this->getFile()){

         return;
    }

    $this->getFile()->move(
        $this->getUploadRootDir(),
        $this->getFile()->getClientOriginalName()
    );

    $this->path = $this->getFile()->getClientOriginalName();
    $this->file = null;
}

在您的控制器中，GET和POST的简单上传操作：

public function UploadAction()
{
    $document = new Media();
    $form = $this->createFormBuilder($document)
       ->add('file')
       ->getForm();

    if ($this->getRequest()->isMethod('POST')) {
        $form->handleRequest($this->getRequest());
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();
            $account = $em->getRepository('AccountingAccountBundle:Account')->findOneBy(array('id' => $accountId));

            $document->setAccount($account);
            $document->upload();

            $em->persist($document);
            $em->flush();
        }
    }

    return array('form' => $form->createView());
}

如果此示例无法在您的服务器上运行，则可能是您的文件系统权限存在问题。

Answer 3

问题出在路径目录中，只需再一个目录返回 dir 。＆＃39; /../../../../../ web / uploads＆＃ 39 ;;像这样：）

Answer 4

最简单的想法：

在树枝中创建普通表单，并尝试将/ rebuilt用于下面的自己需要的特性。

我在连接到实体的一些简单上传中使用它，它不是一个很棒的代码（没有文件验证等），但它对你来说是一个好的开始。

如果trait在实体目录中，则配置

$ location变量

以下用户特征上传（

<?php
 namespace AdminBundle\Entity;

 use Symfony\Component\HttpFoundation\File\UploadedFile;
 use Symfony\Component\Filesystem\Filesystem;
 use Symfony\Component\Finder\Finder;

 trait LinkFileTrait
{
     private $location='/../../../web/media/link' ;
     private $path=__DIR__;

public function checkDir(){
    $id=$this->getId();

    $fs=new Filesystem();
    if(!$fs->exists($this->path.$this->location))
        $fs->mkdir($this->path.$this->location);
    $this->setImagePath($this->path.$this->location.'/'.$id.'');
    if(!$fs->exists($this->getImagePath()))
        $fs->mkdir($this->getImagePath());
}

public function getImages(){
    $this->checkDir();
    $finder = new Finder();
    return $finder->files() ->in($this->getImagePath());
}

public function getRandomImage(){
    $images=$this->getImages();
    $images=iterator_to_array($images);
    if(count($images)<1)
        return null;
    shuffle($images);
    return $images[0];
}

public function UploadFile(UploadedFile $file){
    $file->move($this->getImagePath().'/',$file->getClientOriginalName());

}

public function removeImage($file){
    $this->checkDir();
    $fs=new Filesystem();
    if($fs->exists($this->getImagePath().'/'.$file))
        $fs->remove($this->getImagePath().'/'.$file);
}

public function imageExists($image){
    $this->checkDir();
    $fs=new Filesystem();

    return $fs->exists($this->getImagePath().'/'.$image);
}


public function getRelativePath($path){
    $path=strtr($path,"\\","/");
    $x=explode('../web/',$path);
    return $x[1];
}


public function getImageName($path){
    $path=strtr($path,"\\","/");
    $x=explode('/',$path);
    return $x[count($x)-1];
}

public function getFileName($path){
    $x=explode('/',$path);
    return $x[count($x)-1];
}


}

并在您的控制器中

  public function imagesAction(Link $link,Request $request)
{
    $link->checkDir();
    $images=$link->getImages();

    if($request->getMethod()=='POST'){

        $file=$request->files->all()['plik'];
        $link->UploadFile($file);
    }
    return array('link'=>$link,'images'=>$images);
}

使用symfony上传图像。图像未保存在正确的路径中
