how to calculate the bundle price for my selections. The magento core funtions are more preferable.

Answer 1

I solved it by own method, not sure its acceptable or not.

$bundle_option = Mage::app ()->getRequest ()->getParam('bundle_option');
$bundle_option_array = call_user_func_array('array_merge', $bundle_option);
$price =  Mage::Helper('airhotels/bundle')->getBundlePrice($productid,$bundle_option_array);

my helper file is

public function getBundlePrice($productId,$bundle_option_array) {
$product = new Mage_Catalog_Model_Product();
$product->load($productId);
$price=0;
$selectionCollection = $product->getTypeInstance(true)->getSelectionsCollection($product->getTypeInstance(true)->getOptionsIds($product), $product);
foreach($selectionCollection as $option) 
{
    if (in_array($option->getSelectionId(), $bundle_option_array)){
        $price += $option->price; 
    }
}
return $price;
}
