I created reward_point in the sales_order table, whenever someone purchased a few points stored in that field.

Now I need to display that point into the admin order view page, I already override sales_order_view and create the block, but failed to get the value of the reward point in view page.


  <referenceContainer name="order_additional_info">
      <block class="SimpleMagento\RewardPoint\Block\Sales\Order\ShowReward" name="sales_order_view_custom" template="order/view/custom.phtml" />


class ShowReward extends \Magento\Sales\Block\Adminhtml\Order\Totals
   public function _initTotals(){

    $this->_totals['reward_point'] = new \Magento\Framework\DataObject(
            'code' => 'reward_point',
            'strong' => true,
            'value' => $this->getSource()->getReward(),
            'label' => __('Reward Point'),
            'area' => 'footer',
    return $this;

for the value of the reward_point I have override Order.php, which similarly look like:

public function getReward()
    return $this->getData(OrderInterface::reward_point);

but for that, I have to override OrderInterface, any other way to achieve this functionality?


You can try below code in your block, it might be helpful to get Reward point custom field value.

protected $orderRepository;

public function __construct(
 \Magento\Sales\Model\OrderRepository $orderRepository
) {
   $this->orderRepository = $orderRepository;

public function getReward()
   $order_id = $this->getRequest()->getParam('order_id');
   $order =  $this->orderRepository->get($order_id);
   return $order->getRewardPoint(); // your reward point
  • Thanks I just did that :) – Sagar Parikh Jan 7 '20 at 11:02
  • if possible can you please let me how can I place my block below Total Orders box – Sagar Parikh Jan 7 '20 at 11:02

Other way is

protected $factory;

public function __construct(Context $context,
                            OrderFactory $factory,
                            array $data = [])
    parent::__construct($context, $data);
    $this->factory = $factory;

public function getReward(){
    $id = $this->getRequest()->getParam('order_id');
    $getOrder = $this->factory->create()->load($id);
    return $getOrder['reward_point'];
