Add custom variable to product andd access it later in the invoice

[chillermiller]

Hello everybody,

 

I want to add a custom variable to my product, which is modifieable in product-list.tpl and product.tpl. Later in the shopping cart and invoice, it will be added to the description as well. As far as I know, i have to do this by overwriting this function in ajax-cart.js:

ajaxCart.add($('#product_page_product_id').val(), $('#idCombination').val(), true, null, $('#quantity_wanted').val(), null, 'white');

How do I display for example my variable 'white' in my shopping-cart.tpl?

 

Any hints how to accomplish this?
