Below is my code in question. I will list a few things below it.

if ($product->getTypeId() == 'configurable') {
    $child = $product->getTypeInstance(true)->getProductByAttributes($params['super_attribute'], $product);
    $product = $child;
$message = $this->__('%s was added to your shopping cart.', Mage::helper('core')->escapeHtml($product->getName()));
$response['status'] = 'SUCCESS';
$response['message'] = $message;
$topCart = $this->getLayout()->getBlock('topCart')->toHtml();
$response['topCart'] = $topCart;
$response['image'] = (string)Mage::helper('catalog/image')->init($product, 'thumbnail');
$response['name'] = $product->getname();
$response['price'] = Mage::helper('core')->formatPrice($product->getPrice(), true);

When $product is a simple product outright, there is no issue. The functions $product->getname(), $product->getPrice(), and init($product, 'thumbnail'), all return valid results.

When $product is found to be configurable, it's child product replaces it. I can then get the name, thumbnail but when I call the getprice function I get no results.

I don't understand why this would be. Anyone out there care to elucidate?

  • what value is given by $product->getPrice()

  • @AmitBera When it is removed from the formatprice() it is returning nothing. Within formatprice I am getting 0.00. However, like I said, this only happens when the product is the child of a configurable product. When it is a simple product outright it is working as intended. Oct 21, 2014 at 15:44

Mage_Catalog_Model_Product_Type_Configurable::getProductByAttributes uses Mage_Catalog_Model_Product_Type_Configurable::getUsedProductCollection to load items, this collection does not load the price from eav. So you have to load the product:

$child = $product->getTypeInstance(true)->getProductByAttributes($params['super_attribute'], $product);
$product = Mage::getModel('catalog/product')->load($child->getId());

Now use $product->getFinalPrice(), this also implemets catalog price rules etc.


  • $product->getFinalPrice() still returns $0.00. Oct 22, 2014 at 12:25
