Retrieve items on Order Magento 2

Question

My objective is to send an order to our backend system when a order is placed within our Magento 2 instance.

The code to send the order object is working. My question is what is the optimum approach to retrieve item data (e.g. price, subtotal, total, sku, etc.).

I'm using the following to retreive the order and items.

$orderId = $this->_order->load($order);
$billing = $orderId->getBillingAddress();
$items = $orderId->getAllItems();
foreach ($items as $item) {
        $itemPrice = $item->getPrice();
        $itemSku = $item->getSku();
}

Is iterating through $items to get price, sku, etc. the best way or is there a Magento2 collection/method I should be using?

Thanks

Answer 1

$order = $this->_objectManager->create('Magento\Sales\Model\Order')->load($orderId);
$orderItems = $order->getAllItems();

You done it using objectManager

Answer 2

The correct way to load Order object (which will carry the items info in itself) is via Repository objects.

Inject the order repository in your constructor

protected $orderRepository;

public function __construct(
    ...
    \Magento\Sales\Api\OrderRepositoryInterface $orderRepository,
    ....
) {
    ....
    $this->orderRepository = $orderRepository;
    ....
}

and use in required method as:

$order = $this->orderRepository->get($orderId);
foreach ($order->getAllItems() as $item) {
// var_dump($item->getData());
}

If you use

$order->getAllVisibleItems()

Instead of

$order->getAllItems()

You will get better results

More Explanation :

If you take a look at sales_order_item table you'll see that there are two rows for each item in the order, one of them with useless data and the other one with the data that you'd probably need. Well if you use getAllItems() you'll get those two lines, but if you use getAllVisibleItems() you'll get only the rows with the useful data. I hope this does help you!

below i code which will help you to get order items (i called in Block class)

<?php
namespace Sugarcode\Test\Block;

class Test extends \Magento\Framework\View\Element\Template
{
    protected $order;

    public function __construct(
        \Magento\Backend\Block\Template\Context $context,
        \Magento\Sales\Model\Order $order,
        array $data = []
    ) {
        $this->order = $order;
        parent::__construct($context, $data);
    }



    public function _prepareLayout()
    {
        return parent::_prepareLayout();
    }
    public function getOrderItems()
    {
        $order=$this->order->load(1);

        return $order->getItems();

    }
}
