If at first youdon't succeed, then give up and try a bulldozer approach: -
Create a seperate php script for the new window.
>From your existing page, open the new window with javascript, passing in the
required id parameter to identify the cart contents that you want to display. If
you can't identify that shoppers contents by a single ID, (or at worst a combo of
a couple of ID's) then you will have to pass all the required parameters as
javascript variables and in the querystring you use to open the new window so that
PHP can find them.
To pass a php value to javascript, try something like: -
Calling funciton: -
<a href=javascript:AddItem($ID)> where $ID is a php variable in your main script
and the jscript function is something like: -
function AddItem(IDent)
{
msgWindow=window.open("AddWindow.php?ID="+IDent,"displayWindow","menubar=no,width=400,height=200")
}
It's not ideal, but it should get you up and running!
