Hi Iam尝试在cakephp中上载图像，但它仅在数据库表中插入jpg，Iam收到的错误如下：

警告（2）：move_uploaded_file（C：\xampp\htdocs\实践\app\webroot\img\Image\3.jpg）：打开流失败：没有这样的文件或目录[APP\Controller\UsersController.php，第98行]

警告（2）：移动上传的文件（）[函数.移动上传的文件]：无法移动'C:\xampp\tmp\php24B4。tmp'到'C:\xampp\htdocs\practice\app\webroot\img\image\3。jpg'[APP\Controller\userscoontroller.php，第98行]

这是我的密码

控制器：

$extension =strtolower(pathinfo($this->request->data['User']['image_file']['name'],PATHINFO_EXTENSION));
            if( 
                !empty ($this->request->data['User']['image_file']['tmp_name'])&&
                in_array($extension,array('png','jpeg','jpg'))
              )
              {
                move_uploaded_file
                (
                    $this->request->data['User']['image_file']['tmp_name'],
                    IMAGES.'image'.DS.$this->User->id.'.'. $extension
                );
                $this->User->saveField('image',$extension);
              }
              elseif(!empty ($this->request->data['User']['image_file']['tmp_name']))

和视图：

<?php echo $this->Form->create('User',array('type' =>'file'));?>
<?php echo $this->Form- >input('image_file',array('label'=>'Image(jpeg,jpg,png)','type' =>'file'));?>
<?php echo $this->Form->end();?>
