Help with Sending Attributes Through Form

[hxiao]

I am trying to update a shopping cart based on a wizard, but am having trouble conceptualizing how to set the attributes correctly for things I am adding to a shopping cart.

 

It is set as such in application_top.php:

 

$attributes = $_REQUEST['id'][$_REQUEST['products_id'][$i]]

 

where $i is a counter.

 

I need a little direction regarding what 'id' ends up looking like. It seems like 'id' is a mapping between product ids and (option, value) pairs. However, that doesn't appear to be working.

 

Can anyone point out what I'm missing? It would be greatly appreciated.

 

Thanks!
