I'm trying to create a Module that gets the order data when an order is placed and sends it to a third party using FTP.

I've created an Observer that gets called by the sales_order_place_after event.

My Observer code:


use Magento\Framework\Event\ObserverInterface;

class Orderobserver implements ObserverInterface
    public function __construct(
        \Magento\Quote\Model\QuoteFactory $quoteFactory,
        \Magento\Sales\Model\Order $order,
        \Digitaq\CbFashion\Helper\Data $helper
        $this->_order = $order;
        $this->_helper = $helper;

    public function execute(\Magento\Framework\Event\Observer $observer)
        $order = $observer->getEvent()->getOrder();

The observer gets called succesfully and the writeShp method also does, but it's not possible for me to dump the $order variable, as that leads to a redirect to the cart without the order being fulfilled. How can I see this variable so I know what data I can pull?

Try to log your data by using this way:

protected $logger;
public function __construct(\Psr\Log\LoggerInterface $logger)
    $this->logger = $logger;

You use debug, exception, system for PSR Logger for example:


Hopefully, this will help you.

  • This also redirects me back to the cart with the product still in it. Nothing is logged as well. I tried calling my observer on the checkout_onepage_success event but there is no orderdata available through the observer then. Does anyone have any other suggestions?

If you add the following you will get a error but you will see what's in the observer.

return var_dump($observer);


Temporary print log with new file

$writer = new \Zend\Log\Writer\Stream(BP . '/var/log/logtest.log');
$logger = new \Zend\Log\Logger();
$logger->info('Simple Text Log'); // Simple Text Log
$logger->info('Array Log'.print_r($myArrayVar, true)); // Array Log

If you are in dire need of seeing data from an observer, You can do it in a dirty/nasty way - You can print it with die(); + var_dump(); in Your Observer class

public function execute(Observer $observer)
