Add to cart is not working

I tested the product in your link above and it seems to be working properly for me though?

So if I add “Szatkownica do warzyw Hebel V3 z wk?adk? blokuj?c?” to cart, a popup appears, promoting another product “Miska do Szatkownicy do warzyw Hebla V3”.

Now, since your upsell product “Miska do Szatkownicy do warzyw Hebla V3” is a variable product, your user will be redirected to the upsell product’s product page for user to choose the variation (color).

From our plugin description:

• For complementary product that the product type is SIMPLE: If the user clicks yes, the complementary product will also be added to cart.
• For complementary product that the product type is VARIABLE: If the user clicks yes, you can choose whether to redirect your user to the complementary product’s product page, OR to let your user choose a variant on the popup and add that variant to cart without navigating away from popup.

If you don’t want them to get redirected to the product page of the upsell product, please use popup template with the name of “Variable Upsell” when you configure your popup.

Let me know how it goes.

My bad, it works fine when I added variants. Thank you!

I have one more question. It is possible to change variants dropdown list to swatches?

We don’t have that kind of feature unfortunately, but if you are comfortable with editing codes, you could hack the default popup template and change the dropdown list to swatches. It’s not really advisable though, because your changes will be gone each time you update the plugin.

But anyway, glad to hear it’s working!
