I'm trying to get access to the grand total of the order but for some reason am unable to access this variable.

I have tried multiple solutions by creation modules but nothing seems to be working.

namespace Creation\OrderSuccess\Block;

class Success extends \Magento\Checkout\Block\Onepage\Success {

    public function getOrder() {
        return $this->_checkoutSession->getLastRealOrder();


echo $block->getOrder() outputs null, if I echo $block->getGrandTotal() I also get null.

I can't seem to figure out where I'm missing the connection to access this data.

  • Can i assume that when your testing you are refreshing the page? if so when the page is refreshed that data is removed to prevent this on a temporary basis i never recommend editing the core files on a permenant basis only for quick testing. go to vendor/magento/module-checkout/Controller/Onepage/Success.php on line 22 comment out $session->clearQuote();which will prevent the checkout from clearing itself so you can do proper test Commented Aug 21, 2019 at 13:34
  • Yeah you are correct although I have already tried this and still wasn't getting the data I needed. Are you able to access the quote inside of success.php?

  • I am able to retreive the last order id and then load that via my own block i never extend the success block as i prefer my code to be independand of core blocks as magento is constantly changing class names and depricating things Commented Aug 21, 2019 at 14:14
  • Do you have an example I would be able to take reference from?

Something like this should work no issue tried and tested.


namespace Vendor\Module\Block\Checkout;

use Magento\Checkout\Model\Session;
use Magento\Framework\View\Element\Template\Context;
use Magento\Sales\Model\OrderFactory;

class Success extends \Magento\Framework\View\Element\Template

    protected $scopeConfig;

    protected $checkoutSession;

    protected $orderModel;

    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,  
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
        \Magento\Checkout\Model\Session $checkoutSession,       
        \Magento\Sales\Model\Order $orderModel,
        array $data = []        
    ) {
        parent::__construct($context, $data);       
        $this->_scopeConfig = $scopeConfig;
        $this->_checkoutSession = $checkoutSession;
        $this->_orderModel = $orderModel;

    public function getRealOrderId()
        $lastorderId = $this->_checkoutSession->getLastOrderId();
        return $lastorderId;

    public function getOrder() {

        $orderId = $this->getRealOrderId();
        $_order = $this->_orderModel->loadByIncrementId($orderId);

        return $_order;
