问题
does anyone know where the original checkout field settings are, within the Woocommerce plugin files? E.g The original field labels and placeholders etc?
回答1:
There is no Checkout fields settings in Woocommerce…
But you can customize them using:
- The Woocommerce Developer Documentation reference to customize checkout fields
- or any of the availaible plugins which most of them are commercial.
1) Checkout fields are managed essentially by 3 Woocommerce classes:
- WC_Checkout Class using get_checkout_fields() method (and get_value() method)
- WC_Countries Class using get_default_address_fields() method and get_address_fields() method
- WC_Customer Class used also for My account Address fields.
And uses woocommerce_form_field() template function where the different field types are defined.
2) The main hooks involved in customizations are:
- woocommerce_default_address_fields filter hook and StackOverFlow related threads
- woocommerce_checkout_fields filter hook and StackOverFlow related threads
- woocommerce_billing_fields filter hook and StackOverFlow related threads
- woocommerce_shipping_fields filter hook and StackOverFlow related threads
- woocommerce_form_field_{$args\[type\]} filter hook and StackOverFlow related threads
3) The main related templates involved that can be overridden through via the theme are:
- checkout/form-checkout.php
- checkout/form-billing.php
- checkout/form-shipping.php
- checkout/form-loging.php

For Original Fields please visit on your "woocommerce/templates/checkout/form-billing.php"
Here you will see a function
//This below line of code is responsible to get the fields
$fields = $checkout->get_checkout_fields( 'billing' );
//this below code is resposnible to echo those fields/labels etc
woocommerce_form_field( $key, $field, $checkout->get_value( $key ) );
If you want to go in depth please visit woocommerce/includes/wc-template-fucntions.php "function woocommerce_form_field( $key, $args, $value = null )", check this.
Hope this may help you out!
