I want to change each and every selected bundle items price on addtocart

How can I do this.

At present I am doing like below :

$item = $observer->getQuoteItem();
if ($item->getParentItem()) {$item = $item->getParentItem();}

By doing above, it only change Parent Bundle product Price.

Please check screenshot :

enter image description here

So is there any posibility to change price of bundle items with custom price which will display properly even after order place in order view page. I have go through the code and find that "Bundle Items's" price are saved in infobuyrequest.

$sel_bundle_options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());

So is it possible to change price directly into that ? But after placing an order if we check on order view pages,it will display.

  • I would recommend using a total model instead of wasting time on editing the buyrequest.

You can do below code while adding product to the cart.

$cart = Mage::helper('checkout/cart')->getCart()->getQuote()->getAllItems();
$price = '';
foreach ($cart as $i)
  if ($i->getId() == '') // Dont getting id for currently adding bundle item.
     $options = $i->getOptions();
     foreach ($options as $option)
        if ($option->getCode() == 'bundle_selection_attributes')
           $unserialized = unserialize($option->getValue());
           $price = 10; // YOUR CUSTOM PRICE
           $unserialized['price'] = number_format($price, 2, '.', ',');
     catch (Exception $e)
