Magento 2 - Save custom shipping address' fields to quote_address table

Question

I have did all the steps from this tutorial and it works well for updating custom fields in quote table.

In my case, I need to add custom fields to quote_address and (later) in customer_address_entity tables.

I've created a plugin for: <type name="Magento\Checkout\Model\ShippingInformationManagement">.

What I've got so far:

#Vendor/module/Plugin/Checkout/Model/Checkout/ShippingInformationManagementPlugin.php


public function beforeSaveAddressInformation(
    ShippingInformationManagement $subject,
    $cartId,
    ShippingInformationInterface $addressInformation
) {
    $this->logger->log(\Psr\Log\LogLevel::DEBUG, 'INDEXIS');

    $extAttributes = $addressInformation->getExtensionAttributes();

    $number = $extAttributes->getNumber();
    $complement = $extAttributes->getComplement();
    $district = $extAttributes->getDistrict();
    $area_code = $extAttributes->getAreaCode();
    $this->logger->log(\Psr\Log\LogLevel::DEBUG, "number: " . $number);
    $this->logger->log(\Psr\Log\LogLevel::DEBUG, "complement: " . $complement);
    $this->logger->log(\Psr\Log\LogLevel::DEBUG, "district:" . $district);
    $this->logger->log(\Psr\Log\LogLevel::DEBUG, "area_code:" . $area_code);


    $quote = $this->quoteRepository->getActive($cartId);

    $quote->setNumber($number);
    $quote->setComplement($complement);
    $quote->setDistrict($district);
    $quote->setAreaCode($area_code);
}

It logs the values in debug.log file but won't update the fields in my database.

I know that my mistake is trying to set my custom fields in $this->quoteRepository. So my question is: What object should I use to set my custom fields in quote_address table?

There will more questions related to this topic, but only after this one is solved.

Answer 1

For address save, you need to assign value into address object. Here is an example:

Here delivery_date is a new custom column of quote_address table

$billingAddress = $addressInformation->getBillingAddress();
$billingAddress->setDeliveryDate('2016-09-30 12:22:00');

If you need to assign shipping address too, then you need to do it the same way. Basically magento uses two rows for addresses, in quote/order; One address for billing and one for shipping.

$shippingAddress = $addressInformation->getShippingAddress();
$shippingAddress->setDeliveryDate('2016-09-30 12:22:00');
