在产品页显示可配置产品所属的简单产品的库存，解决方案如下：

打开文件mage/catalog/block/product/view/type/configurable.php，大概在85行可以找到如下代码：

foreach ($this->getAllowAttributes() as $attribute) {
                    $productAttribute = $attribute->getProductAttribute();
                    $attributeValue = $product->getData($productAttribute->getAttributeCode());
                    if (!isset($options[$productAttribute->getId()])) {
                        $options[$productAttribute->getId()] = array();
                    }
                    if (!isset($options[$productAttribute->getId()][$attributeValue])) {
                        $options[$productAttribute->getId()][$attributeValue] = array();
                    }
                    $options[$productAttribute->getId()][$attributeValue][] = $productId;
    
    
    
                }

替换成

foreach ($this->getAllowAttributes() as $attribute) {
    
    
                    $productAttribute = $attribute->getProductAttribute();
                    $attributeValue = $product->getData($productAttribute->getAttributeCode());
                    if (!isset($options[$productAttribute->getId()])) {
                        $options[$productAttribute->getId()] = array();
                    }
                    if (!isset($options[$productAttribute->getId()][$attributeValue])) {
                        $options[$productAttribute->getId()][$attributeValue] = array();
                    }
                    $options[$productAttribute->getId()][$attributeValue][] = $productId;
                    //Alex
                $options['qty'][$product -> getAttributeText($productAttribute->getName())] = floor($product->getStockItem()->getQty()); 
                }

然后在大概128行找到如下代码：

$info['options'][] = array(
                            'id'    => $value['value_index'],
                            'label' =>  $value['label'] ,
                            'price' => $this->_preparePrice($value['pricing_value'], $value['is_percent']),
                            'products'   => isset($options[$attributeId][$value['value_index']]) ? $options[$attributeId][$value['value_index']] : array(),
                        );

替换成

$info['options'][] = array(
                            'id'    => $value['value_index'],
                            'label' => ($options['qty'][$value['label']] <= 0) ? $value['label'] . ' * out of stock' : $value['label'] . " * (".$options['qty'][$value['label']]." in stock)",
                            'price' => $this->_preparePrice($value['pricing_value'], $value['is_percent']),
                            'products'   => isset($options[$attributeId][$value['value_index']]) ? $options[$attributeId][$value['value_index']] : array(),
                        );

然后前台通过一点JS处理下就可以得到类似淘宝的效果
