这篇文章主要介绍了用PHP做了一个领取优惠券活动的示例代码,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧。
业务需求
优惠券活动,具体还是要根据自己的需求。以下是最近实现的优惠券活动,主要的业务需求:根据后端设置优惠券模板,用户类型设置,优惠券活动的开始与结束时间,最后生成不同的优惠券活动链接。
代码环境:
源码主要laravel5.8,一整个活动要贴的代码很多,下面主要贴核心代码,仅供参考。主要还是要根据自己的业务需求来实现功能吧。
以下是后端截图,做成模块化
前端需要做的设置与限制:
1 判断优惠券是否存在或者停用
2 判断活动开始时间与优惠券开始时间
接着领取活动优惠券,需要判断以下情况:
1 活动已结束
2 活动为开始时
3 活动为新用户领取,而领取的用户是老用户
4 活动为老用户领取,而领取的用户是新用户
5 优惠券是否领取完
6 已领取过优惠券提示
7 领取成功
下面核心代码实现
- /**

- * Author:cyw0413
- * @param $params
- * @return array
- * @throws \Exception
- */
- public function doCoupon($params)

用户领取优惠券并发放优惠券

领取成功,则发放优惠券
