Magento 2 Checkout Observer Debugging – Step-by-Step Guide

checkoutevent-observermagento2

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:

<?php

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();
        $this->_helper->writeShp($order);
    }
}

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?

Best Answer

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:

$this->logger->info($yourCustomData);
$this->logger->debug($yourCustomData);

Hopefully, this will help you.

Magento 2 – Set Custom Price of Product When Adding to Cart Code Not Working

Please use this even checkout_cart_product_add_after, and also I suggest you that

ObserverInterface has only one method which is execute, so write your code in this method.

And do not use parent Item because while you are adding to cart any item then price depend upon child item so the best way is to use directly that item object that you are getting. So best practice is to use that item itself.

And also return $this object at the end of your code inside execute method.

For eg: namespace Navin\Testcart\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Framework\App\RequestInterface;

class CustomPrice implements ObserverInterface
{
    public function execute(\Magento\Framework\Event\Observer $observer) {

        $item=$observer->getEvent()->getData('quote_item');
        $product=$observer->getEvent()->getData('product');
        // here i am using item's product final price
        $price = $item->getProduct()->getFinalPrice()+10; // 10 is custom price. It will increase in product price.
        // Set the custom price
        $item->setCustomPrice($price);
        $item->setOriginalCustomPrice($price);
        // Enable super mode on the product.
        $item->getProduct()->setIsSuperMode(true);
        return $this;
    }

}

Hope this will help you. :)
