Add extra fields to page

At what level? To the add to cart form, or to the cart?

For the Add to Cart form, there’s sample code here:

At both levels thanks. Have added the extension but don’t know how to make it show on front page ?? What files are the current fields in Thanks.

What do you mean by ‘on front page’? The extension requires modification; it’s not a plug-in intended to be used out right.

I don’t have an example available for how to add custom fields to the cart right now; I’ll work on that when I have a chance. It uses the filter ‘mt_cart_custom_fields’ to add them and the action ‘mt_handle_custom_cart_data’ to process them, for reference.

Here’s an example for custom cart fields:
