Uploadify:显示来自 HTTP 响应的错误消息 [英] Uploadify: show error message from HTTP response

问题描述

如果服务器在使用 Uploadify 上传文件时返回错误(HTTP 响应代码 != 200)，则上传的文件将变为红色背景并显示如下消息:

file.jpg (52.78KB) - HTTP 错误

表示存在 HTTP 错误.但这对用户来说不是很有用.如何让它显示更详细的错误信息?比如:图片无效"或配额已满"?

我想在 HTTP 响应正文中传递这些消息，但 Uploadify 没有接收它们.有没有已知的方法可以将错误消息传回 Uploadify?

解决方案

看看uploadify 论坛中的这两篇帖子如何处理错误

onError 显示正在发生的事情和上传脚本错误报告

里面有很多有用的信息..

更新

以下内容似乎对我有用..

'onComplete': function(a, b, c, d, e){如果 (d !== '1'){警报(d)；}别的{alert('文件名:' + c.name + '已上传');}}

加上这个版本的uploadify脚本

If the server returns an error (HTTP response code != 200) when uploading a file with Uploadify, the uploaded file gets a red background and a message is show like this:

file.jpg (52.78KB) - HTTP Error

indicating that there was a HTTP Error. But that's not very useful to the the user. How can I make it show a more detailed error message? Like: 'Not a valid image' or 'Quota full'?

I was thinking of passing those messages in the HTTP response body, but Uploadify doesn't pick them up. Is there a known way to pass error messages back to Uploadify?

解决方案

Take a look at these two posts in the uploadify forum on how to handle errors

onError to display what's happening and Upload script error reporting

there is a lot of useful info in there ..

Update

The following seems to do the trick for me ..

'onComplete': function(a, b, c, d, e){
                    if (d !== '1')
                        {
                        alert(d);
                        }
                    else
                        {
                        alert('Filename: ' + c.name + ' was uploaded');
                        }
                  }

coupled with this version of the uploadify script

<?php

    if (!empty($_FILES)) 
    {
        $tempFile = $_FILES['userfile']['tmp_name'];

        $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
        $targetFile =  str_replace('//','/',$targetPath) . $_FILES['userfile']['name'];

        move_uploaded_file($tempFile,$targetFile);

        switch ($_FILES['userfile']['error'])
        {     
            case 0:
             $msg = ""; // comment this out if you don't want a message to appear on success.
             break;
            case 1:
              $msg = "The file is bigger than this PHP installation allows";
              break;
            case 2:
              $msg = "The file is bigger than this form allows";
              break;
            case 3:
              $msg = "Only part of the file was uploaded";
              break;
            case 4:
             $msg = "No file was uploaded";
              break;
            case 6:
             $msg = "Missing a temporary folder";
              break;
            case 7:
             $msg = "Failed to write file to disk";
             break;
            case 8:
             $msg = "File upload stopped by extension";
             break;
            default:
            $msg = "unknown error ".$_FILES['userfile']['error'];
            break;
        }
    }
    if ($msg)
        { $stringData = "Error: ".$_FILES['userfile']['error']." Error Info: ".$msg; }
    else
        { $stringData = "1"; } // This is required for onComplete to fire on Mac OSX
    echo $stringData;
?>
