在 cakephp 中上传图片

Question

您好，我正在尝试在 cakephp 中上传图像，但它仅在数据库表中插入 jpg 时出现错误

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

警告 (2): move_uploaded_file() [function.move-uploaded-file]: 无法将 'C:\xampp\tmp\php24B4.tmp' 移动到 'C:\xampp\htdocs\praactise\app\webroot \img\image\3.jpg' [APP\Controller\UsersController.php，第 98 行]

这是我的代码

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']))

并查看：

<?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();?>

确保您的图片文件夹路径正确？

C:\xampp\htdocs\practise\app\webroot\img\image\3.jpg

image 文件夹存在于您的 img 文件夹中吗？

请更换这个

move_uploaded_file($this->request->data['User']['image_file']['tmp_name'],IMAGES.'image'.DS.$this->User->id.'.'. $extension);

$this->User->saveField('image',$extension);

到

move_uploaded_file($this->request->data['User']['image_file']['tmp_name'],IMAGES.'image'.DS.$this->request->data['User']['image_file']['name']);

$this->User->saveField('image',$this->request->data['User']['image_file']['name']);
