Jquery Uploadify: Rename Uploaded File

I have been searching for two days to find a solution which will let me upload employee image and rename it, I couldn't find any. Turns out it's pretty simple, I have to just pass the filename as query string and do a little modification in uploadify.php file.

1. Passing the filename as part of the query string - followed by '?' mark include the filename with the paramater 'script'
   

   'script' : 'uploadify/uploadify.php?name=imagename'

   //don't worry about the extension
2. Modify the following line
   

   $targetFile =  str_replace('//','/',$targetPath) . 
   $_FILES['Filedata']['name'];

   
   with this
   

   if(isset($_GET['name'])){
   $targetFile =  str_replace('//','/',$targetPath) . $_GET['name']. 
           substr($_FILES['Filedata']['name'],-4);
    } else{
       $targetFile =  str_replace('//','/',$targetPath) .
         $_FILES['Filedata']['name'];
    }

I hope this is helpful
