Ajax Validation in Multistep Checkout for WooCommerce
The Ajax validation examines whether each mandatory field has inputs. It also checks whether, all the field with validations, inputs entered are valid while the next button is clicked at the Checkout steps. It is a built-in feature. Validation happens when a user navigates from one-step to another via Next/ Previous Button.
