基于：http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html
我制作了一个图像模型：
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Filesystem\Filesystem;
/**
* @ORM\Entity
* @ORM\Table(name="images")
* @ORM\Entity(repositoryClass="AppBundle\Entity\ImagesRepository")
* @ORM\HasLifecycleCallbacks
*/
class Images
{
/**
* @ORM\Column(type="string", length=60)
* @ORM\Id
* @ORM\GeneratedValue(strategy="CUSTOM")
* @ORM\CustomIdGenerator(class="AppBundle\Doctrine\AutoIdGenerate")
*/
private $id;
/**
* Filename of the Image
* @ORM\Column(type="string", length=100)
*/
private $name;
/**
* Filename of the Thumbnail
* @ORM\Column(type="string", length=100)
*/
private $name_small;
/**
* ImageGroup og the Image
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\ImageGroups", inversedBy="images")
*/
private $group;
/**
* @Assert\File(maxSize="20000000")
*/
private $file;
private $upload_dir='images';
private $temp;
/**
* Get file.
*
* @return UploadedFile
*/
public function getFile()
{
return $this->file;
}
/**
* Sets file.
*
* @param UploadedFile $file
*/
public function setFile(UploadedFile $file,$upload_dir)
{
$this->file = $file;
// check if we have an old image path
if (isset($this->name))
{
// store the old name to delete after the update
$this->temp = $this->name;
$this->name = null;
}
else
{
$this->name = sha1(uniqid(mt_rand(), true)).'.'.$file->guessExtension();
}
$this->name_small="small_".$this->name;
$this->upload_dir=$upload_dir;
return $this;
}
/**
* @ORM\PrePersist()
* @ORM\PreUpdate()
*/
public function preUpload()
{
if (null !== $this->getFile())
{
// do whatever you want to generate a unique name
$filename = sha1(uniqid(mt_rand(), true));
$this->name = $filename.'.'.$this->getFile()->guessExtension();
$this->name_small='small_'.$this->name;
}
}
public function getUploadRootDir()
{
return __DIR__.'/../../../../web/'.$this->upload_dir;
}
/**
* @ORM\PostPersist()
* @ORM\PostUpdate()
*/
public function upload()
{
if (null === $this->getFile())
{
return;
}
// if there is an error when moving the file, an exception will
// be automatically thrown by move(). This will properly prevent
// the entity from being persisted to the database on error
//-- Make the Thumbnail Here --
$dir=$this->getUploadRootDir();
echo $dir;
$fs = new Filesystem();
if(!$fs->exists($dir))
{
echo "\nCreating\n";
$fs->mkdir($dir,0777,true);
}
$this->getFile()->move($dir, $this->name);
$file=$dir.'/'.$this->name;
// check if we have an old image
if (isset($this->temp))
{
// delete the old image
unlink($this->getUploadRootDir().'/'.$this->temp);
// clear the temp image path
$this->temp = null;
}
$this->file = null;
}
/**
* @ORM\PostRemove()
*/
public function removeUpload()
{
$file = $this->getAbsolutePath();
if ($file)
{
unlink($file);
}
}
/**
* Get id
*
* @return string
*/
public function getId()
{
return $this->id;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Get nameSmall
*
* @return string
*/
public function getNameSmall()
{
return $this->name_small;
}
/**
* Set group
*
* @param \AppBundle\Entity\ImageGroups $group
*
* @return Images
*/
public function setGroup(\AppBundle\Entity\ImageGroups $group = null)
{
$this->group = $group;
return $this;
}
/**
* Get group
*
* @return \AppBundle\Entity\ImageGroups
*/
public function getGroup()
{
return $this->group;
}
/**
* Set name
*
* @param string $name
*
* @return Images
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Set nameSmall
*
* @param string $nameSmall
*
* @return Images
*/
public function setNameSmall($nameSmall)
{
$this->name_small = $nameSmall;
return $this;
}
}
我还制作了自定义存储库以进行上传：
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\EntityRepository;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use AppBundle\Entity\Images;
class ImagesRepository extends EntityRepository
{
public function add($file,$group_id,$user_id)
{
if(empty($group_id)) return -1;
if(empty($user_id)) return -2;
/*Do stuff for uploads*/
/*End of Do stuff for uploads*/
$em = $this->getEntityManager();
$imagesGroups = $em->getRepository('AppBundle:ImageGroups')
->getUserImageGroups($user_id,null,$group_id);
if(empty($imagesGroups) ||(is_int($imagesGroups) && $imagesGroups<0)) return -3; //Null and negative values are false
if(empty($file)) return -4;
$image=new Images();
$image->setFile($file,'images')->setGroup($imagesGroups);
try
{
$em->persist($image);
$em->flush();
return ['id'=>$image->getId(),'image'=>$image->getName(),'thumb'=>$image->getNameSmall()];
}
catch (\Exception $e)
{
echo $e->getMessage();
return false;
}
}
public function delete($user_id,$image_id)
{
if(empty($image_id)) return -1;
if(empty($user_id)) return -2;
$em = $this->getEntityManager();
try
{
$q=$em->createQueryBuilder('i')
->from('AppBundle:Images','i')
->innerJoin('i.group', 'g')
->innerJoin('AppBundle:Users','u')
->select('i')
->where('i.id=:iid')
->andWhere('u.id=:uid')
->setParameter(':uid', $user_id)
->setParameter(':iid', $image_id)
->setMaxResults(1)
->getQuery();
$data=$q->getOneOrNullResult();
if(empty($data)) return -3;
/*Delete Image Stuff*/
/*End Of: Delete Image Stuff*/
$em->remove($data);
$em->flush();
return true;
}
catch (\Exception $e)
{
echo $e->getMessage();
return false;
}
}
}
当我成功执行POST操作（我使用curl测试上面的代码）时出于某种原因我得到以下错误：
The file "IMG_20160305_155302.jpg" was not uploaded due to an unknown error.
通过回显Exception消息。
我原本认为这是我的文件系统上的权限问题因此在文件夹/home/pcmagas/Kwdikas/php/apps/symphotest/src/AppBundle/Entity/../../../../web/images
我设置了以下权限：
drwxrwxrwx 2 www-data www-data 4096 Μάρ 5 23:02 images
但似乎不是问题所在。我想知道还有什么呢。 我可以有解决方案吗？
编辑1： 我检查了php.ini上的upload_max_filesize并且是2M，我上传的文件是56,0 Kbytes。
答案 0 :(得分：0)
UploadedFile实例在某种程度上没有在控制器中进行核心设置。
为了获取文件输入，我创建了这个类：
<?php
namespace AppBundle\Helpers;
use Symfony\Component\HttpFoundation\File\UploadedFile;
class MyUploadedFile
{
/**
*Storing Uploaded Files
*/
private $files=null;
function __construct($string)
{
if(isset($_FILES[$string]))
{
$files=$_FILES[$string];
if(is_array($files['name']))
{
$this->files=array();
$tmp_files=array();
/**
*Sanitizing When Multiple Files
*/
foreach($files as $key=>$val)
{
foreach($val as $key2=>$val2)
{
$tmp_files[$key2][$key]=$val2;
}
}
foreach($tmp_files as $val)
{
$this->files[]=new UploadedFile($val['tmp_name'],$val['name'],$val['type'],$val['size'],$val['error']);
}
}
elseif(is_string($files['name']))
{
$this->files= new UploadedFile($files['tmp_name'],$files['name'],$files['type'],$files['size'],$files['error']);
}
}
}
/**
*@return {UploadedFile} Or {Array of UploadedFile} or null
*/
public function getFiles()
{
return $this->files;
}
}
?>
特别是在这些行中
$this->files= new UploadedFile($files['tmp_name'],$files['name'],$files['type'],$files['size'],$files['error']);
$this->files[]=new UploadedFile($val['tmp_name'],$val['name'],$val['type'],$val['size'],$val['error']);
因此，当您手动创建上传文件时，大小会出现在错误
之前
