I'm trying to check the shipping address of an order being placed using an event observer. I need to get the shipping address before the order is placed so I can cross reference it to places I do not wish to ship to, and either proceed with the order or throw an exception.


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
  <event name="sales_order_place_before">
    <observer name="ob7_RestrictedRegions_sales_order_place_before" instance="ob7\RestrictedRegions\Observer\OrderPlaceBefore"/>


<?php namespace ob7\RestrictedRegions\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\Event\Observer;
use Magento\Framework\Exception\PaymentException;

class OrderPlaceBefore implements ObserverInterface

   public function execute(Observer $observer)

       $order = $observer->getEvent()->getOrder();
       $shippingAddress = $order->getShippingAddress();
       throw new PaymentException(__('Error will appear here'));            

This results in an error. Can someone advise me on the proper way to collect the shipping address here?

Removing $shippingAddress = $order->getShippingAddress(); stops the error. But then how do I get the shipping address?

Please use the quote object to get the shipping address for before placing order event(observer) data.

$order = $observer->getEvent()->getData('order');

$quote= $order->getQuote();

$shippingAddress = $quote->getShippingAddress();
