我有一个实体 Agence 相关的OneToOne与实体照片
的Agence
class Agence
{
/**
* @ORM\OneToOne(targetEntity="Project\DashboardBundle\Entity\Photo", cascade={"persist"})
* @ORM\JoinColumn(nullable=true)
*/
private $photo;
这是实体照片
的简介<?php
namespace Project\DashboardBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**

class Photo
{
/**

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

*/
private $url;
/**

public $file;
public function setFile($file)
{
$this->file = $file;
if (null !== $this->url) {
$this->tempFilename = $this->url;
$this->url = null;
$this->alt = null;

}
public function getFile()
{
return $this->file;
}
private $tempFilename;
/**

public function preUpload()
{
if (null === $this->file) {
return;
}
$this->url = $this->file->guessExtension();
$this->alt = $this->file->getClientOriginalName();
}
/**

public function upload()
{
if (null === $this->file) {
return;
}
if (null !== $this->tempFilename) {
$oldFile = $this->getUploadRootDir().'/'.$this->id.'.'.$this->tempFilename;
if (file_exists($oldFile)) {
unlink($oldFile);
}
}
$this->file->move(
$this->getUploadRootDir(),
$this->id.'.'.$this->url
);
}
/**
* @ORM\PreRemove()
*/
public function preRemoveUpload()
{
$this->tempFilename = $this->getUploadRootDir().'/'.$this->id.'.'.$this->url;
}
/**
* @ORM\PostRemove()
*/
public function removeUpload()
{
if (file_exists($this->tempFilename)) {
unlink($this->tempFilename);
}
}
public function getUploadDir()
{
return 'uploads/img';
}
protected function getUploadRootDir()
{
return __DIR__.'/../../../../web/'.$this->getUploadDir();
}
public function getWebPath()
{
return $this->getUploadDir().'/'.$this->getId().'.'.$this->getUrl();
}
尝试上传照片时出现此错误:
FatalErrorException:错误:在D:\ wamp \ www \ agence \ src \ Project \ DashboardBundle \ Entity \ Photo.php第135行中的非对象上调用成员函数guessExtension()
,奇怪的是,这个相同的代码在另一个实体上工作正常!!
解决 我忘了添加{{form_enctype(form)}}
答案 0 :(得分:1)
action="{{ path('your_path') }}" {{form_enctype(form)}} method="post"
