How do I get an order collection in admin order view using the email address of the current order?

Question

I am trying to build an order history table to display previous orders (order number/date/items ordered, etc) from a customer order in the admin order view (Magento\Sales\Block\Adminhtml\Order\View\Info). This table should list all previous orders that used the email from the current order regardless if they are a guest or have an account.

I did this in Magento 1.9 by calling the model directly in the template and running through the loop for orders and items for those orders:

<?php
$orderCollection = Mage::getModel('sales/order')->getCollection()->addFieldToFilter('customer_email',$_order->getCustomerEmail())->addFieldToSelect('*')->setOrder('entity_id', 'desc');
$recordNumber = 1;
if ($orderCollection->getSize() >= 2) { 

$orderCollection->getSelect()->limit(20);
foreach($orderCollection as $order){
$history_id = Mage::getModel('sales/order')->loadByIncrementId($order->getIncrementId())->getId();
$orders = Mage::getModel("sales/order")->load($order->getId()); 
$orderHistoryDate = $this->formatDate($order->getCreatedAtStoreDate(), 'medium', true);
$items = $orders->getAllVisibleItems();

//list orders (order number, date, status)

foreach($items as $item):

//list items in orders (qty ordered, item name, sku)

endforeach;

}
}

How can I do this with dependency injection on Magento 2?

Answer 1

You can add dependency injection like this :

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);
    }

and get collection like:

$orderCollection = $this->order->getCollection()->addFieldToFilter('customer_email',$_order->getCustomerEmail())->addFieldToSelect('*')->setOrder('entity_id', 'desc');
$recordNumber = 1;
if ($orderCollection->getSize() >= 2) { 

$orderCollection->getSelect()->limit(20);
foreach($orderCollection as $order){
$history_id = $this->order->loadByIncrementId($order->getIncrementId())->getId();
$orders = $this->order->load($order->getId()); 
$orderHistoryDate = $this->formatDate($order->getCreatedAtStoreDate(), 'medium', true);
$items = $orders->getAllVisibleItems();

//list orders (order number, date, status)

foreach($items as $item):

//list items in orders (qty ordered, item name, sku)

endforeach;
