H6 Smart Checkout Fields for WooCommerce gives you precise control over your checkout form without the complexity of larger checkout customisation plugins.

Edit existing WooCommerce checkout fields, add your own custom fields, show or hide fields based on what the customer enters, validate what they type, and organise everything from a clean field-builder interface designed for real stores.

Built for the Classic WooCommerce Checkout.

Key Features

Conditional field logic

Show or hide any custom field based on what the customer selects in another checkout field.

For example, only show a “VAT number” field when the billing country is a specific country, or reveal a “Delivery notes” box when a delivery option is chosen. Hidden fields are not required and are skipped during validation, so conditional fields never block checkout.

Keep the data you collect clean.

Minimum and maximum length
Pattern matching with a custom regular expression

Validation is enforced both in the browser and again on the server when the order is placed.
