Using Session Variables inside an ajax document

For some reason I've having problems reading this session variable within an 开发者_运维百科ajax document, I've got this inside online.php:

` session_start();

if (isset($_SESSION['username'])) { $username = $_SESSION['username']; } `

For some Reason this is not setting username even when the session var is being used on the host page, i call on the php file every second using this

` $(document).ready(function() {

var refreshId = setInterval(function() { $('#timeval').load('online.php'); }, 1000);

$("#stop").click(function() { clearInterval(refreshId); }); }); `

Am I doing something wrong, or is this not even possible?? Any advice would really help thanks alot!

you have to send response for ajax request as json array. after that - you can use it.

here is the sample googled tutorial: http://viralpatel.net/blogs/2009/04/jquery-ajax-tutorial-example-ajax-jquery-development.html

ps: i wonder that you didn't ever look what was returned back from server for your ajax request.

I had changed my session var to memberName
