magento更新产品属性值 eg. visibility

$attributeData = array('Visibility'=>Mage_Catalog_Model_Product_Visibility::VISIBILITY_NOT_VISIBLE);

$product = Mage::getModel('catalog/product')->load($productId);

                $storeIds = $product->getStoreIds();
                foreach($storeIds as $storeId){
                    Mage::getSingleton('catalog/product_action')->updateAttributes(array($productId), $attributeData, $storeId);

                }

注意:storeId为store的id号,如果需要更新默认值(default value),可以将storeid设置为0.
