Add to Cart on quantity change

[hassanyousuf]

Is there a way to add products on cart when user changes the quantity of a product?

Hi @hassanyousuf ,

your question is not clear. did you mean if customer inputs anything in quantity box and it should update the whole cart without clicking on any button and loads by ajax, if yes then follow this :

Hello.

I think the link you provided only supports the cart page. I want to apply
it on the whole website.
