Hi Nicolas,
I have followed this topic and used it successfully on our own site.
However, some of our products consist of a main product with options and/or variants.
When a customer orders, the transaction shows up in the back end order report as typically) two distinct items i.e. the main product itself + the option/variant.
Is it possible to somehow modify or concatenate the 'add to cart' html string so that two products get added to the cart when that link is activated? In our case, that would be the main product itself plus its option/variant.
Regards
PhilP
