codeigniter

Hello,

I have a shopping cart in Codeigniter in which products are added to the cart using (jQuery) Ajax. In the header of each page it displays the number of contents in the cart using

<?php echo $this->cart->total_items(); ?>

How can I update/refresh this variable when a product is added to the cart, as I am using AJAX to add products to the cart and thus the page isn't being reloaded when products are added. It seems pointless to use AJAX to do asyncronous stuff if I have to reload the page to get the new number of total items from the server.

Many thanks.
