Getting always NULL in Cart Item GetPrice() function

Question

I'm manually adding some products to the cart:

$product = Mage::getModel('catalog/product')->load(113);
$params = array(
  'product' => 113,
  'qty' => 1
);
$request = new Varien_Object();
$request->setData($params);
$cartHelper->getCart()->addProduct($product, $request); 

But the price is always empty (or null).

I've been debugging the execution through

Mage_Checkout_Model_Cart->addProduct(...)
Mage_Sales_Model_Quote->addProduct(...)
Mage_Sales_Model_Quote->addProductAdvanced(...)

and finally:

protected function _addCatalogProduct(Mage_Catalog_Model_Product $product, $qty = 1)
{
    $newItem = false;
    $item = $this->getItemByProduct($product);
    if (!$item) {
        $item = Mage::getModel('sales/quote_item');
        $item->setQuote($this);
        if (Mage::app()->getStore()->isAdmin()) {
            $item->setStoreId($this->getStore()->getId());
        }
        else {
            $item->setStoreId(Mage::app()->getStore()->getId());
        }
        $newItem = true;
    }

    /**
     * We can't modify existing child items
     */
    if ($item->getId() && $product->getParentProductId()) {
        return $item;
    }

    $item->setOptions($product->getCustomOptions())
        ->setProduct($product);

    // Add only item that is not in quote already (there can be other new or already saved item
    if ($newItem) {
        $this->addItem($item);
    }

    return $item;
}

But the price is not there, in that $item :(

Any help would be much appreciated.

Answer 1

The price in a quote item is set in \Mage_Sales_Model_Quote::collectTotals

So you need to run \Mage_Sales_Model_Quote::collectTotals to have a price, this happens when a page is rendered, after reload.

You can run this manually, but be careful, unfortunately the method stores a bunch of cached prices, which may be reused in a wrong way and might lead to wrong prices if called twice!

Answer 2

Along with the suggested below collectTotals() call please try to set store id to the product before load. $storeId = Mage::app()->getStore()->getId(); $product = Mage::getModel('catalog/product') ->setStoreId($storeId) ->load(113);
