I can\'t find the way to ovveride billing state and post code.

How can I edit the other parts of existing billing fields like billing state and post code?

Th

Answer 1

This is the complete way for billing state and billing post code override, keeping the billing selector with options.

Here is the code the fully functional and tested code:

1. Unsetting billing state and post code checkout fields

add_filter( 'woocommerce_checkout_fields' , 'partial_unsetting_checkout_fields' );
function partial_unsetting_checkout_fields( $fields ) {
     unset($fields['billing']['billing_state']);
     unset($fields['billing']['billing_postcode']);

     return $fields;
}

2. Reinserting custom billing state and post code checkout fields

add_filter( 'woocommerce_default_address_fields' , 'art_override_default_address_fields' );
function art_override_default_address_fields( $address_fields ) {

  // @ for state
    $address_fields['billing_state']['type'] = 'select';
    $address_fields['billing_state']['class'] = array('form-row-wide');
    $address_fields['billing_state']['required'] = true;
    $address_fields['billing_state']['label'] = __('State', 'my_theme_slug');
    $address_fields['billing_state']['placeholder'] = __('Enter state', 'my_theme_slug');
    $address_fields['billing_state']['default'] ='Choice 1';
    $address_fields['billing_state']['options'] = array(
        'option_1' => 'Choice 1',
        'option_2' => 'Choice 2',
        'option_3' => 'Choice 3'
    );

    // @ for postcode
    $address_fields['billing_postcode']['type'] = 'text';
    $address_fields['billing_postcode']['class'] = array('form-row-wide');
    $address_fields['billing_postcode']['required'] = true;
    $address_fields['billing_postcode']['label'] = __('Postcode', 'my_theme_slug');
    $address_fields['billing_postcode']['placeholder'] = __('Enter your postcode', 'my_theme_slug');


    return $address_fields;
}

Naturally this goes on function.php file of your active child theme or theme

Note concerning the 'class' property

There is 2 ways to handle it:

• The field is alone in one line (width 100%), you use: 'form-row-wide'
• There is 2 fields side by side on the same line, you use:
  • 'form-row-first' for the first field
  • 'form-row-last' for the second field

Answer 2

//-------------------------- OVERRIDING BILLING STATE FIELD -------------------------------//

//Removing previous one by using unset
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

// Our hooked in function - $fields is passed via the filter!
function custom_override_checkout_fields( $fields ) {
     unset($fields['billing']['billing_state']);

     return $fields;
}
        

add_filter( 'woocommerce_default_address_fields' , 'art_override_default_address_fields' );

function art_override_default_address_fields( $address_fields ) {
    // @ for state
    $address_fields['Billing_State']['type'] = 'text';
    $address_fields['Billing_State']['class'] = array('form-row-wide');
    $address_fields['Billing_State']['required'] = true;
    $address_fields['Billing_State']['label'] = __('State', 'my_theme_slug');
    $address_fields['Billing_State']['placeholder'] = __('Enter state', 'my_theme_slug');

    return $address_fields;
}
