只获得可配置产品的简单产品

Question

我正在使用下面的代码

$configurable= Mage::getModel('catalog/product_type_configurable')->setProduct($_product);
                $simpleCollection = $configurable->getUsedProductCollection()->addAttributeToSelect('*')->addFilterByRequiredOptions();
                $productAttributeOptions = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray($_product);
                $attributeOptions = array();
                foreach ($productAttributeOptions as $productAttribute) {

                        foreach ($productAttribute['values'] as $attribute) {
                            $attributeOptions[$productAttribute['label']][] = 
                            array('id' => $attribute['value_index'],
                                'label' => $attribute['label'],
                                'mainId' => $productAttribute['attribute_id'] );
                        }

                    }


            return $attributeOptions;

但它给了我所有简单产品的清单，即使那些库存不可用。 我只想要一份有库存的可配置产品的简单产品清单。 我怎样才能获得可配置产品的库存产品

Answer 1

您可以查看商品库存状态0 - 没有库存或1 - 库存

$configurable= Mage::getModel('catalog/product_type_configurable')->setProduct($_product);
$simpleCollection = $configurable->getUsedProductCollection()->addAttributeToSelect('*')->addFilterByRequiredOptions();
/* -------- Add this  ------- */
$simpleCollection->getSelect()->join('cataloginventory_stock_status', 'cataloginventory_stock_status.product_id = e.entity_id', array('stock_status'));
$simpleCollection->getSelect()->where("`cataloginventory_stock_status`.`stock_status` = 1");

$productAttributeOptions = $_product->getTypeInstance(true)->getConfigurableAttributesAsArray($_product);
$attributeOptions = array();
foreach ($productAttributeOptions as $productAttribute) {

        foreach ($productAttribute['values'] as $attribute) {
            $attributeOptions[$productAttribute['label']][] = 
            array('id' => $attribute['value_index'],
                'label' => $attribute['label'],
                'mainId' => $productAttribute['attribute_id'] );
        }

    }


return $attributeOptions;
