As you know, you can tick the “Enable AJAX add to cart buttons on archives” checkbox in the WooCommerce settings in order to add products to cart from the Shop / Category / Tag / loop pages without refreshing the page.
This is great for certain businesses, especially those who sell in bulk and where customers know exactly what they need to buy without the need of checking the single product page.
The bad news is that the Ajax Add to Cart button only allows you to add 1 item to the cart i.e. there is no quantity input field. The other bad news is that the Ajax Add to Cart button only works for simple products, while for variable ones it will turn into a “Select options” link without the possibility of adding a variation to cart from there.
In this tutorial, we will see how to turn the WooCommerce shop into an… Ajax cart with quantity inputs. Enjoy!
