Magento – Magento observer is not viewing product details

event-observermagento-1.8PHP

I have created custom checkout_cart_save_before observer in magento by create the following files

app/etc/modules/Cart_Override.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Cart_Override>
            <codePool>local</codePool>
            <active>true</active>
            <depends>
                <Mage_Contacts />
            </depends>
        </Cart_Override>
    </modules>
</config>

app/code/local/Cart/Override/etc/config.xml

<?xml version="1.0"?>
<config>
    <global>
        <models>
            <cartoverride>
                <class>Cart_Override_Model</class>
            </cartoverride>
        </models>
        <events>
            <checkout_cart_save_before>
                <observers>
                    <cart_override_qty_observer>
                        <type>singleton</type>
                        <class>Cart_Override_Model_Qtyc_Observer</class>
                        <method>checkout_cart_save_before</method>
                    </cart_override_qty_observer>
                </observers>
            </checkout_cart_save_before>     
        </events>
    </global>
</config>

and app/code/local/Cart/Override/Model/Qtyc/Observer.php

class Cart_Override_Model_Qtyc_Observer extends Varien_Event_Observer
{

    public function checkout_cart_save_before($observer)
    {
        $action  = Mage::app()->getFrontController()->getAction();
        $product = $observer->getProduct();
        echo "<pre>";
        print_r($product);
        echo "</pre>";
        die();
    }

}

The observer is working fine, when i click the add to cart button it is going to checkout_cart_save_before function. But i could not get the product values from the observer using the following code inside the checkout_cart_save_before function

$product = $observer->getProduct();

I have to add something for get the product details from the observer parameter?….any guess??

The event itself does not have the products directly. See where it is being called:

Mage::dispatchEvent('checkout_cart_save_before', array('cart'=>$this));

You only have the cart object as a parameter to the event. You can get the items from the cart and find the product from each item.

$items = $observer->getEvent()->getCart()->getItems()

Will give you the cart items collection.

And then you would need to run this:

foreach($items as $item) {
    $product = $item->getProduct();
    //here you do what you want with the product.
}

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. :)
