Hello all... PHP guy here just getting into javascript/jQuery...

I'm using jQuery's sortable accordion (http://jqueryui.com/accordion/#sortable) in an application to display elements that are in a set order. I was wondering if anyone could point me in the right direction on how to add ajax functionality to this so that when a user reorders the accordion list the order is updated on the server side.

I'm sure this is pretty basic ajax stuff but i'm a complete noob with client side scripting
