how to get product group price by customer group id, without logged in

Question

I need to replace the product price with group price for the product which is in the cart.[without logged in any customers].

I am getting a product from the cart and getting a price and other information. I am unable to get product customerGroupId and group price and all.

$cart = Mage::getModel('checkout/cart')->getQuote();
        $cartItems = $cart->getAllVisibleItems();
        foreach ($cartItems as $item)
        {
            //Mage::log(print_r($item->getCustomerGroupId(), true));
         //   Mage::log(print_r($item, true));
            $item->setCustomerGroupId(4);
            Mage::log(print_r($item->getPrice(), true));
 Mage::log(print_r($item->getGroupPrice(), true));
}

The above code not able to print group price or unable to set product customerGroup

Help me to get an answer for this, Thanks in advance:)

Answer 1

Charlie.you can not get Customer group price from item`.

Here $item Mage_Sales_Quote_Item object and it not product object Mage_Catalog_Product .

So, you can not get group price from $item->getGroupPrice() and but you can only item price on here and using $item->getPrice() you can get Product cart price not group price.

Ifyou need to load product Object (Mage::getModel('catalog/product')) by product id($item->getProduct()->getId())
