我正在使用http://fineuploader.com，它會自動爲圖像名稱生成uuid。我想將上傳的圖像uuid存儲在數據庫中。我已經發現它應該有可能得到與uuid php $uuid = $_REQUEST['qquuid'];如何在數據庫中保存優化加載器uuid？
我已經測試把它放在我的php代碼，但沒有保存。我可以通過我的mysql插入從javascript代碼傳遞給php函數嗎？
如何從傳遞給php函數的上傳圖像中獲取所有uuid，以便將它們保存到我的數據庫中？

/**
* 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.
