How to get customer name and adress through order increment id/order id in magento 2?

Question

I want to fetch and show which customer bought which product and from where on front end. The issue is i am unable to fetch the above details through order increment id/order id.

So how can i get customer details on checkout_onepage_success page.

Answer 1

Well i would suggest to use Automatic Dependency injection but if you are using object manager then you can do it like this

<?php //NOT TESTED THOUGH
      --------------------
//Get Object Manager Instance
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('Magento\Sales\Model\Order')->loadByIncrementId($IncrementId); //Use increment id here.
$order->getCustomerName(); // Check that class. There are lot of functions for getting customers data. Though first you should check if any API available. Because thats a better solution.

Answer 2

<?php
// logined customer
 if ($order->getCustomerFirstname()) {
   $customerName = $order->getCustomerName();
 } else {
  // guest customer
   $billingAddress = $order->getBillingAddress();
   $customerName = $billingAddress->getFirstname() . ' ' . 
   $billingAddress->getLastname();
 }
echo $customerName;

?>
