如何使用plupload在laravel 4中获取更改的文件名？

I am new to laravel. I try to upload image by using plupload + laravel 4. I can change the file name but I want to have that changed file name to save in the database. How could I do it please?

At my vendor/forjuth/plupload/src/Plupload/UploadHandler.php

I added time() to avoid overwrite

  $result = $file->move(\Config::get('plupload::plupload.upload_dir'),time().$file->getClientOriginalName());
