envexlabs Posted October 25, 2007 Share Posted October 25, 2007 Hey, I have a cart that displays the total of all items in the cart. The items are added/removed from the cart via ajax, and i want to be able to update the total when an item is added/removed from the cart. How would i go about creating a loop or something that is constantly checking to see if $total has been changed? Thanks, envex.

premiso Posted October 25, 2007 Share Posted October 25, 2007 Why create a loop? Whenever an item is added or removed, change the total accordingly...Since you know when it needs to happen, no need to loop.
