标签: cart-rules

我在Magento 2中创建了新表,用于存储自定义promorules,现在我已经为事件创建了观察者controller_action_predispatch_checkout_cart_couponPost,在观察者中我想检查用户是否输入了任何自定义规则,然后根据该规则应用折扣.

     *
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
     */
    public function execute(\Magento\Framework\Event\Observer $observer)

        $controller = $observer->getControllerAction();
        $couponCode = $controller->getRequest()->getParam('coupon_code');

        $objectManager =   \Magento\Framework\App\ObjectManager::getInstance();
        $connection = $objectManager->get('Magento\Framework\App\ResourceConnection')->getConnection('\Magento\Framework\App\ResourceConnection::DEFAULT_CONNECTION'); 
        // get list of …
