woocommerce_(type)fields │ filter-hook │ WC 1.0

Important note on this filter: Changes to address fields can and will be overridden by the woocommerce_default_address_fields. The locales/default locales apply on top based on country selection. If you want to change things like the required status of an address field, filter woocommerce_default_address_fields instead.

Usage

add_filter( 'woocommerce_(type)fields', 'wp_kama_woocommerce_typefields_filter', 10, 2 );
