Billing Address Custom Field

Question

Magento ver. 2.2.2

I added an extra attribute for Customer Address.

It works as aspected in customer address edit (frontend and backend).

In checkout page:

For Shipping Address everything is working fine but is not saved in sales_order_address table (works for quote_address).

For Billing Address:

• if shipping address is used it works as shipping address.
• if is different from shipping address but use an existing customer address it works as shipping address.
• if is new created custom attribute is not saved (not in order,quote or customer)

For Billing Address I've got those files:

app\code\Company\Module\view\frontend\web\js\action\set-billing-address-mixin.js

/*jshint browser:true jquery:true*/
/*global alert*/
define([
 'jquery',
 'mage/utils/wrapper',
 'Magento_Checkout/js/model/quote'
], function (,ドル wrapper,quote) {
 'use strict';
 return function (setBillingAddressAction) {
 return wrapper.wrap(setBillingAddressAction, function (originalAction) { 
 var billingAddress = quote.billingAddress();
 if (billingAddress && billingAddress.customAttributes){
 if (billingAddress['extension_attributes'] === undefined) {
 billingAddress['extension_attributes'] = {};
 }
 var taxcode = billingAddress.customAttributes['tax_code'];
 if($.isPlainObject(taxcode)){
 taxcode = taxcode['value'];
 }
 billingAddress['extension_attributes']['tax_code'] = taxcode;
 // pass execution to original action ('Magento_Checkout/js/action/set-shipping-information')
 }
 return originalAction();
 });
 };
});

app\code\Company\Module\Plugin\Checkout\PaymentInformation.php

<?php
namespace Company\Module\Plugin\Checkout;
class PaymentInformation
{
 protected $logger;
 public function __construct(\Psr\Log\LoggerInterface $logger)
 {
 $this->logger = $logger;
 }
 public function beforeSavePaymentInformation(
 \Magento\Checkout\Model\PaymentInformationManagement $subject,
 $cartId,
 \Magento\Quote\Api\Data\PaymentInterface $paymentMethod,
 \Magento\Quote\Api\Data\AddressInterface $billingAddress = null
 ) {
 if($billingAddress){
 $billingAddressExtensionAttributes = $billingAddress->getExtensionAttributes();
 if ($billingAddressExtensionAttributes) {
 $customField = $billingAddressExtensionAttributes->getTaxCode();
 $billingAddress->setTaxCode($customField);
 }
 $this->logger->debug('ExtensionAttributes::'.(serialize($billingAddressExtensionAttributes)));
 $this->logger->debug('billingAddress::'.(print_r($billingAddress->debug(),true)));
 } else {
 $this->logger->debug('billingAddress is empty');
 }
 }
}

in debug.log:

Answer 1

In order to get the values from extension attributes to the order i am using this event:

sales_model_service_quote_submit_before

and the code i am using is:

/** @var OrderInterface $order */
 $order = $observer->getEvent()->getOrder();
 $quote = $observer->getEvent()->getQuote();
 $order->getShippingAddress()->setMobilePhone($quote->getShippingAddress()->getMobilePhone());
 $order->getBillingAddress()->setMobilePhone($quote->getBillingAddress()->getMobilePhone());
 $order->getShippingAddress()->setVatRegion($quote->getShippingAddress()->getVatRegion());
 $order->getBillingAddress()->setVatRegion($quote->getBillingAddress()->getVatRegion());

in the observer.

Try this and let me know if it helps

Answer 2

Antonis Galanis's answer should work, but i rather use plugin.

So about the billing address issue, I had to modify requirejs-config.js and point the set-billing-adrress-mixin.js to Magento_Checkout/js/action/place-order.

var config = {
 config: {
 mixins: {
 'Magento_Checkout/js/action/set-shipping-information': {
 'Bileamara_CodiceFiscale/js/action/set-shipping-information-mixin': true
 },
 'Magento_Checkout/js/action/set-billing-address': {
 'Bileamara_CodiceFiscale/js/action/set-billing-address-mixin': true
 },
 'Magento_Checkout/js/action/place-order': {
 'Bileamara_CodiceFiscale/js/action/set-billing-address-mixin': true
 },
 }
 }
};

Then to save custom field in database i've created a plugin

public function afterConvert(
 \Magento\Quote\Model\Quote\Address\ToOrderAddress $subject,
 $result,
 \Magento\Quote\Model\Quote\Address $object
){
 $result->setTaxCode($object->getTaxCode());
 return $result;
}

That made me wonder, because for quote_addres table fieldset.xml was enough and \Magento\Quote\Model\Quote\Address\ToOrderAddress->convert() should use it but it doesn't.

$orderAddressData = $this->objectCopyService->getDataFromFieldset(
 'sales_convert_quote_address',
 'to_order_address',
 $object
);

Be aware, for NOT LOGGED IN customer I need another plugin for GuestPaymentInformationManagement
