如何在数据库中保存fineuploaders uuid？

Question

I am using http://fineuploader.com that automatically generates uuid to the image names. I want to store the uploaded image uuid in a database. I have found out that it should be possible to get the uuid with php $uuid = $_REQUEST['qquuid'];

I have tested to put it it in my php code but nothing is saved. Can I pass it from the javascript code to a php function with my mysql insert?

How do I get all the uuid from the uploaded images passed to a php function so I can save them to my database?

php code I use to upload the files

<?php
/**
 * PHP Server-Side Example for Fine Uploader S3.
 * Maintained by Widen Enterprises.
 *
 *
 * This example:
 *  - handles non-CORS environment
 *  - handles size validation and no size validation
 *  - handles delete file requests for both DELETE and POST methods
 *  - Performs basic inspections on the policy documents and REST headers before signing them
 *  - Ensures again the file size does not exceed the max (after file is in S3)
 *  - signs policy documents (simple uploads) and REST requests
 *    (chunked/multipart uploads)
 *
 * Requirements:
 *  - PHP 5.3 or newer
 *  - Amazon PHP SDK (only if utilizing the AWS SDK for deleting files or otherwise examining them)
 *
 * If you need to install the AWS SDK, see http://docs.aws.amazon.com/aws-sdk-php-2/guide/latest/installation.html.

Answer 1

Fine Uploader's S3 uploader sends an upload success POST request to your server after the file has been successfully sent to S3. A number of parameters are sent in the payload of this request, which is URL encoded. The name of the uuid parameter for the S3 upload success request is "uuid". So, you can parse it server-side, in your upload success POST handler, with $_POST['uuid'].
