Multiple products with customer input

Hi Wadim,

WooCommerce actually does addon quantity calculation itself. I.e. we are adding addon price to product price once, and if you add more than one product with addon to the cart – WooCommerce makes the multiplication itself. Your task however can be done with Booster, however I’m not sure if this will be good enough. There are “Custom Checkout Fields” and “Checkout Fees” modules in Booster. Using both of them you can achieve that if some product is in cart, then new field is added to the checkout page and if that field is selected – fee is added to the cart. So basically it’s what you need, but instead “addon” being on single product page, it’s displayed on checkout page.
