Add woocomerce products

Hello !

Hope you guys are doing great.

I’ve already build a form with extra dev that redirect users on the cart page and add product to their cart, but It has been long and painful (I had to manually add all possiblities in the behavior section with a url ?add-to-cart=myproduct) So I was wondering : is there a way to link a product directly to a field ? for example if a certain checkbox is check, a linked product is added ?

Thanks a lot !
