Question

我正在尝试使用sonata-project从后端上传Symfony 2中的图像。我现在面临的挑战是将图像插入数据库表并上传到指定路径。我已经为我的上传文件夹写了可写权限。我不知道我错过了什么，但这是我采取的步骤。

class HomeEnumerate
{

// ...
protected function getUploadDir()
{
    return 'uploads/houses';
}

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

public function getWebPath()
{
    return null === $this->house_picture ? null :   $this->getUploadDir().'/'.$this->house_picture;
}

public function getAbsolutePath()
{
    return null === $this->house_picture ? null : $this->getUploadRootDir().'/'.$this->house_picture;
}

}

我已经编辑了我的HomeEnumerate.orm.yml，我已经放入了lifecycleCallbacks：

lifecycleCallbacks:
    prePersist: [ preUpload, setCreatedAtValue, setExpiresAtValue ]
    preUpdate: [ preUpload, setUpdatedAtValue ]
    postPersist: [ upload ]
    postUpdate: [ upload ]
    postRemove: [ removeUpload ]

生成：我编辑了HomeEnumerate实体的实体

class Job
{
// ...

/**
 * @ORM\PrePersist
 */
public function preUpload()
{
     if (null !== $this->file) {
         $this->logo = uniqid().'.'.$this->file->guessExtension();
     }
}

/**
 * @ORM\PostPersist
 */
public function upload()
{
    if (null === $this->file) {
        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
    $this->file->move($this->getUploadRootDir(), $this->logo);

    unset($this->file);
}

/**
 * @ORM\PostRemove
 */
public function removeUpload()
{
    if(file_exists($file)) {
        if ($file = $this->getAbsolutePath()) {
            unlink($file);
        }
    }    
}

}

有人可以帮我上传文件到数据库和文件夹路径。

您也应该在管理类中实现一些回调。实际上，SonataAdminBundle有a cookbook recipe on handling file uploads。希望它能回答你所有的问题。
