[SOLVED] Blueimp jQuery File Upload plugin - "Empty file upload" result PHP

Blueimp jQuery File Upload plugin - "Empty file upload" result PHP

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.

Solution

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
