X-Cart forums - Extra fields in cart.tpl

Hi,

Short version:
Given a productid what is the smarty syntax for getting name/price/description etc?

Long version:
I have used the following method to get extra fields in the cart:
http://forum.x-cart.com/showthread.php?t=50417 (Willieram method)

My plan is to use it to have upsells in the cart. So for product 1 I put '2' in the upsell field, and product details for productid 2 are displayed.

I have this working for thumbnail image. i.e.

Code:

{include file="product_thumbnail.tpl" productid=$product.extra_fields.0.value}

shows the image of the upsell product. I'd like to now get the product name/price etc. I am sure this is on the forum somewhere, but I haven't had any luck finding it. Any help would be appreciated.
