问题描述

这是插件:https://github.com/blueimp/jQuery-File-Uploadp>

上传文件后，我无法从插件获取我想要的响应.

在带有插件的页面上，我有以下内容

$('#fileupload').fileupload('选项'，{'maxNumberOfFiles' :1，网址":/admin/upload_handler.php"});

在 upload_handler.php 中，我成功地从 $_FILES 检索上传的文件并执行操作，然后以 JSON 格式发回响应.我已使用 Firebug 确认响应格式正确:

<代码>[{url":image_url"，thumbnail_url":image_th_url"，delete_url":测试"，删除类型":删除"，名称":foobar.jpg"，尺寸":7419}]

但是回调找不到文件数组，我得到错误:'空文件上传结果'.我觉得我在这里遗漏了一些重要的东西——我在文档、论坛或 Stack Overflow 中找不到任何东西.感谢您的帮助.

从插件版本5开始，json响应发生了变化:https://github.com/blueimp/jQuery-File-Upload/wiki/JSON-Response

所以你只需要调整你的上传类:

$filejson = new stdClass();$filejson->files[] = $fileArray;返回 json_encode($filejson);

你已经完成了

Here's the plugin: https://github.com/blueimp/jQuery-File-Upload

I'm having a problem getting the response I want from the plugin after uploading a file.

On the page with the plugin, I have the following

$('#fileupload').fileupload(
    'option',
    {
        'maxNumberOfFiles' :1,
        'url' : '/admin/upload_handler.php'
    }
);

In upload_handler.php I successfully retrieve the uploaded files from $_FILES and do stuff, then send a response back in JSON. I've confirmed using Firebug that the response is in the proper format:

[ 
    {                
        "url" : "image_url",
        "thumbnail_url" : "image_th_url",
         "delete_url" : "test",
         "delete_type" : "DELETE",
         "name" : "foobar.jpg",
         "size" : 7419
     }
]

But the callback can't find the files array, and I get the error: 'Empty file upload result'. I feel like I'm missing something crucial here--I can't find anything in the docs, forums, or Stack Overflow. I appreciate any help.

Since the version 5 of the plugin, the json response has changed: https://github.com/blueimp/jQuery-File-Upload/wiki/JSON-Response

So you just have tweak your upload class with:

$filejson = new stdClass();
$filejson->files[] = $fileArray;
return json_encode($filejson);

And you're done
