Description
WooCommerce ships with a fixed checkout form. Infixs Checkout Fields lets you add the fields your store actually needs — tax/ID documents (CPF, CNPJ, RG, state registration), person type, date of birth, gender, mobile phone, address number and neighborhood — with masks applied as the customer types and real server-side validation, including document check digits.
Everything is configured from a visual panel inside WooCommerce. Drag fields to set the order, switch each one on or off, mark what is required, choose whether a field takes half a row or the full row, and edit labels and placeholders — including for native WooCommerce fields. A live preview shows exactly how the form will look, with a person-type simulator and a mobile view.
The data does not stop at the checkout: it shows up in order emails, on the order received page, on the admin order screen, on the customer profile and in the WooCommerce REST API (for ERPs and invoicing systems), each destination with its own switch. Addresses are filled automatically from the postcode, digital stores can drop the address block entirely, and settings can be exported and imported between sites.
