I am using a ajax script to send the file IDs and PHP will process it and it should generate the save as dialog box.
Currently without ajax when i process PHP file i can open the download box to save the file.
example:
http://localhost/website/download.php?fid=1005
but when i am sending the fid (using a onclick event of a Image i am sending the ID to JS func ) through Ajax Script this PHP file will execute in server side. so can't retrieve those headers to the page i am sending the request. is there any way to Open this dialog box. issue is now the PHP fle is executing in server side, i have to call it in client side as i feel.
