内容图文

我没有收到任何错误,但我没有复制文件：

$upload_folder = "uploads/";

$name_of_uploaded_file = basename($_FILES['uploaded_file']['name']);

$prefix = date("YmdHis");
$path_of_uploaded_file = "$upload_folder$prefix-$name_of_uploaded_file";
$tmp_path = $_FILES["uploaded_file"]["tmp_name"];

if(is_uploaded_file($tmp_path))
{
  if(!copy($tmp_path,$path_of_uploaded_file))
  {
    $errors .= '\n error while copying the uploaded file';
  }
}

echo $path_of_uploaded_file;
echo $name_of_uploaded_file;
echo $errors;

这在Windows开发环境中运行良好,但部署到Linux Web服务器就是这样做的.我们最初收到了复制错误,然后我们向uploads目录添加了权限.现在我们一无所获.

我也尝试使用move_uploaded_file,没有错误,但在uploads目录中没有生成的文件.

解决方法:

如果is_uploaded_file返回true,也许可以添加一个检查.

if(is_uploaded_file($tmp_path))
{
  if(!copy($tmp_path,$path_of_uploaded_file))
  {
    $errors .= '\n error while copying the uploaded file';
  }
} else {
    $errors .= '\n error while uploading file'; // maybe  upload_max_filesize exceeded
// try to get the specific error

 switch($_FILES['uploaded_file']['error']){
    case 0: //no error; possible file attack!
      echo "There was a problem with your upload.";
      break;
    case 1: //uploaded file exceeds the upload_max_filesize directive in php.ini
      echo "The file you are trying to upload is too big.";
      break;
    case 2: //uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the html form
      echo "The file you are trying to upload is too big.";
      break;
    case 3: //uploaded file was only partially uploaded
      echo "The file you are trying upload was only partially uploaded.";
      break;
    case 4: //no file was uploaded
      echo "You must select an image for upload.";
      break;
    default: //a default error, just in case!  :)
      echo "There was a problem with your upload.";
      break;

}

也许你的upload_max_filesize超出了,或者有另一个不允许上传的服务器设置.
