推荐答案

自2017年WooCommerce 3版本以来，此代码有些过时了.…之间还有一些其他更改.

This code is a bit outdated since 2017 WooCommerce 3 version… Also some other things have changed in between.

这是重新访问的代码:

add_filter('woocommerce_billing_fields' , 'display_billing_vat_fields');
function display_billing_vat_fields($billing_fields){
    $billing_fields['billing_vat'] = array(
        'type' => 'text',
        'label' =>  __('VAT number',  'woocommerce' ),
        'class' => array('form-row-wide'),
        'required' => false,
        'clear' => true,
        'priority' => 35, // To change the field location increase or decrease this value
    );

    return $billing_fields;
}


// Printing the Billing Address on My Account
add_filter( 'woocommerce_my_account_my_address_formatted_address', 'custom_my_account_my_address_formatted_address', 10, 3 );
function custom_my_account_my_address_formatted_address( $fields, $customer_id, $type ) {

    if ( $type == 'billing' ) {
        $fields['vat'] = get_user_meta( $customer_id, 'billing_vat', true );
    }

    return $fields;
}

// Checkout -- Order Received (printed after having completed checkout)
add_filter( 'woocommerce_order_formatted_billing_address', 'custom_add_vat_formatted_billing_address', 10, 2 );
function custom_add_vat_formatted_billing_address( $fields, $order ) {
    $fields['vat'] = $order->get_meta('billing_vat');

    return $fields;
}

// Creating merger VAT variables for printing formatting
add_filter( 'woocommerce_formatted_address_replacements', 'custom_formatted_address_replacements', 10, 2 );
function custom_formatted_address_replacements( $replacements, $args  ) {
    $replacements['{vat}'] = ! empty($args['vat']) ? $args['vat'] : '';
    $replacements['{vat_upper}'] = ! empty($args['vat']) ? strtoupper($args['vat']) : '';

    return $replacements;
}

//Defining the Spanish formatting to print the address, including VAT.
add_filter( 'woocommerce_localisation_address_formats', 'custom_localisation_address_format' );
function custom_localisation_address_format( $formats ) {
    foreach($formats as $country => $string_address ) {
        $formats[$country] = str_replace('{company}\n', '{company}\n{vat_upper}\n', $string_address);
    }
    return $formats;
}


add_filter( 'woocommerce_customer_meta_fields', 'custom_customer_meta_fields' );
function custom_customer_meta_fields( $fields ) {
    $fields['billing']['fields']['billing_vat'] = array(
        'label'       => __( 'VAT number', 'woocommerce' )
    );

    return $fields;
}


add_filter( 'woocommerce_admin_billing_fields', 'custom_admin_billing_fields' );
function custom_admin_billing_fields( $fields ) {
    $fields['vat'] = array(
        'label' => __( 'VAT number', 'woocommerce' ),
        'show'  => true
    );

    return $fields;
}

add_filter( 'woocommerce_found_customer_details', 'custom_found_customer_details' );
function custom_found_customer_details( $customer_data ) {
    $customer_data['billing_vat'] = get_user_meta( $_POST['user_id'], 'billing_vat', true );

    return $customer_data;
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试和工作.

Code goes in function.php file of your active child theme (or active theme). Tested and work.
