I built a custom module which has a custom observer OrderSaveAfter.php. How can I call any function inside the custom observer from another custom code ?

  • @PranayK, for a special case I built custom php code under Magento root, so i need to call observer from it. – Jsparo30 Jul 12 '17 at 11:50

you can use an event called checkout_onepage_controller_success_action

Please follow the below steps

Step 1: app/code/Ewall/Paytrade/etc/frontend/events.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
       <event name="checkout_onepage_controller_success_action">
           <observer name="Ewall_Paytrade_After_Place_Order_Success" instance="Namespace\Module\Observer\AfterOrder"  />

Step 2:

 namespace Ewall\Paytrade\Observer;
 use Magento\Framework\Event\ObserverInterface;
 use Magento\Framework\App\RequestInterface;
 use Magento\Sales\Api\OrderRepositoryInterface;
 use Magento\Customer\Model\Session;
class PlaceOrderSuccess implements ObserverInterface

    protected $orderRepository;
    protected $_session;

    public function __construct(  
    OrderRepositoryInterface $OrderRepositoryInterface,
    \Magento\Customer\Model\Session $session
    ) {
        $this->orderRepository = $OrderRepositoryInterface;
        $this->_session = $session;


    public function execute(\Magento\Framework\Event\Observer $observer) 

           $writer = new \Zend\Log\Writer\Stream(BP.'/var/log/TradeorderSuccess.log');
           $logger = new \Zend\Log\Logger();

           $order_ids = $observer->getEvent()->getOrderIds()[0];
           $order = $this->orderRepository->get($order_ids);           
           $order_id = $order->getIncrementId();               

          foreach ($order->getAllVisibleItems() as $item)



Step 3: after did the changes use di.compile and clear cache & pagecache and and check the same.
