Description

Capture the extra checkout details you need

Checkout Field Editor for WooCommerce lets you add your own fields to the checkout: a GST/VAT number, delivery instructions, a company registration number, a dropdown, a checkbox. Fields are validated, saved securely with the order, and shown on the admin order screen, in emails, on the thank-you page and in My Account.

It is a small, focused plugin: no page builder, no heavy scripts, no slow queries. Object-oriented PHP on standard WooCommerce hooks.

A simple field editor

  • Add, remove and reorder fields on one settings page
  • Types: text, text area, dropdown, checkbox, phone, email
  • Sections: billing, shipping or order notes
  • Required or optional, full or half width, placeholder text
  • Up to 20 fields; a GST/VAT Number field is ready on activation
Custom GST/VAT and order fields on the checkout

Validation you can trust

  • Built-in rules: letters and numbers, numbers only, EU VAT, India GSTIN, email, phone
  • Dropdown values are checked against your options
  • Server-side validation with clear error messages, and WooCommerce's own "required" check
  • Values are sanitised before saving and escaped on output
From checkout to order screen and email

Saved and shown where it matters

  • Saved to the order meta through the order object, so it is HPOS compatible
  • Displayed on the admin order edit screen under the billing address
  • Added to order emails: always to the admin, and to the customer per field
  • Shown on the thank-you page and My Account order view
  • Block checkout support through WooCommerce's Additional Checkout Fields API
