How to set custom price for quote item in checkout_cart_add_product_complete event

Question

I have two event observer in my custom module :

// 1st : checkout_cart_product_add_after
    $item = $observer->getQuoteItem();
    $item->setIsNew(true);

// 2nd : checkout_cart_add_product_complete
    $quote = Mage::getSingleton('checkout/cart')->getQuote();
    $quote_id = $quote->getId(); // quote_id
    foreach($quote->getAllItems() as $quote_item)
    {
        if($quote_item->getIsNew() == true)
        {
            $item = $quote_item;
        }
    }
    // here I want to set custom quote item price and tried below code but it is not working
    $item->setCustomPrice($current_tour_price);
    $item->setOriginalCustomPrice($current_tour_price);
    $item->getProduct()->setIsSuperMode(true);
    $item->save(); // updated

I want to set custom price to quote item in checkout_cart_add_product_complete event.

If I am using the code setCustomPrice and setOriginalCustomPrice in checkout_cart_product_add_after event then it is working.

But I need quote_id as well with dynamic price for some other use and I can't get quote_id in checkout_cart_product_add_after event, so I am using checkout_cart_add_product_complete event.

How to set quote item custom price in event checkout_cart_add_product_complete?

EDIT : With $item->save() it save custom price for quote_item but on change currency custom price not going to update.

I also tried https://stackoverflow.com/a/38243913/4073217 but it is not working in my case.

How to set custom price for quote_item which work with currency change?

Answer 1

You can always update quote, hack it, change value directly in database, but it would be overkill and so far from best practice.

If you need quote_id, you can easily grab it from checkout_card_product_add_after event, because it set quote_item during event dispatch:

Mage::dispatchEvent('checkout_cart_product_add_after', array('quote_item' => $result, 'product' => $product));

All you have to do in your observer is:

$quote_id = $this->getEvent()->getQuoteItem()->getQuote()->getId();

In Magento2:

You can achieve this with Event and Observer. There are following steps:

• Step 1: Create Simple Extension
• Step 2: Declaration of Module
• Step 3: Registration of Module
• Step 4: Activate the Module
• Step 5: Declare event
• Step 6: Create Observer for Custom Price

We need to catch the event - checkout_cart_product_add_after in step 5. In the Observer, write the code to set the custom price.
