why not use serialized arrays stored in cookies to
store a growing list of things that the user is purchasing?
then, it'd be as easy as having this array
stored as a single cookie... ;)
$items = array(
#indexed by item ID
'1003045' => array(
'name' =>'The best movie',
'type'=>'DVD',
'quan'=>1,
),
);
then you could loop thru the array and have
all the information right at your fingertips
print "You ordered $items[$current]['quan'] of $items[$current]['type']";
