Instant Validator is a simple feature which can reduce friction on the checkout form by displaying a validation message as the user input a piece of information in the field. Ideally, it instructs the users through an inline message if the user enters invalid information.
This inline validation feature works on default WooCommerce checkout fields (Required fields) and custom fields created using the Checkout Field Editor plugin (Email, Phone, Number, & URL). It works on both the Min. Length & Max. Length set on each field.
Basic Set up
- Go to Dashboard → WooCommerce → Checkout Form → Advanced Settings page.
- Scroll down to Other Settings and “Enable Inline validation in checkout page.”
