does anyone know where the original checkout field settings are, within the Woocommerce plugin files? E.g The original field labels and placeholders etc?
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, $value = null )", check this.
Hope this may help you out!
There is no Checkout fields settings in Woocommerce…
But you can customize them using:
- The Woocommerce Developer Documentation reference to customize checkout fields
- or any of the availaible plugins which most of them are commercial.
1) Checkout fields are managed essentially by 3 Woocommerce classes:
- WC_Checkout Class using get_checkout_fields() method (and get_value() method)
- WC_Countries Class using get_default_address_fields() method and get_address_fields() method
- WC_Customer Class used also for My account Address fields.
And uses woocommerce_form_field() template function where the different field types are defined.
2) The main hooks involved in customizations are:
- woocommerce_default_address_fields filter hook and StackOverFlow related threads
- woocommerce_checkout_fields filter hook and StackOverFlow related threads
- woocommerce_billing_fields filter hook and StackOverFlow related threads
- woocommerce_shipping_fields filter hook and StackOverFlow related threads
- woocommerce_form_field_{$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
