【问题描述】：

我正在做一个文件上传页面，它会在添加文件之前重命名文件，我收到了这些错误。我已经在网站的文件夹中尝试了chmod -R 777 ./，但它仍然不起作用。

 $dir = Users::currentUser()->id;//each user have his folder
if(move_uploaded_file($_FILES["file"]["tmp_name"], PROOT . 'files' . DS . $dir . DS))
    {
      echo "The file has been uploaded as ".$ran2.$ext;
        //Router::redirect('upload');
    }
    else
    {
      echo "Sorry, there was a problem uploading your file.";
    }

PROOT 被我定义为网站根文件夹define('PROOT','/framework/');，DS 是分隔符(strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') ? define('DS', '/') : define('DS', DIRECTORY_SEPARATOR);。

这就是错误的样子

Warning: move_uploaded_file(/framework/files/4/): failed to open stream: No such file or directory in /opt/lampp/htdocs/framework/app/controllers/UploadController.php on line 46


Warning: move_uploaded_file(): Unable to move '/opt/lampp/temp/phpHz70FG' to '/framework/files/4/' in /opt/lampp/htdocs/framework/app/controllers/UploadController.php on line 46

我也从if 语句中得到错误

Sorry, there was a problem uploading your file.

更新

问题是 ubuntu 权限的原因，在 Windows 上它可以正常工作

【问题讨论】：

标签： php apache chmod

【解决方案1】：

试试看

define('PROOT','framework/');
(strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') ? define('DS', '/') : define('DS', DIRECTORY_SEPARATOR)

$dir = Users::currentUser()->id;//each user have his folder
$path = PROOT . 'files' . DS . $dir . DS;
if(move_uploaded_file($_FILES["file"]["tmp_name"],$path)
    {
      echo "The file has been uploaded as ".$ran2.$ext;
        //Router::redirect('upload');
    }
    else
    {
      echo "Sorry, there was a problem uploading your file.";
    }

【讨论】：

$path = PROOT 。 '文件' 。 DS 。 $目录。 DS;给 echo 路径变量你会得到什么

【解决方案2】：

你必须使用绝对路径喜欢

 define('PROOT','/opt/lampp/htdocs/framework/');
