php優惠券的實作方式:1、建立一個前端文件,並判斷優惠券是否存在或停用;2、創建PHP範例文件;3、透過「public function doCoupon($params){ ...}」等方式處理優惠券領取狀況即可。

php優惠券的實現方式是什麼

本文操作環境:windows7系統、PHP7.4版、DELL G3電腦

php優惠券的實作方式是什麼?

用PHP做了一個領取優惠券活動的範例程式碼

業務需求

優惠券活動,具體還是要根據自己的需求。以下是最近實現的優惠券活動,主要的業務需求:根據後端設置優惠券模板,用戶類型設置,優惠券活動的開始與結束時間,最後生成不同的優惠券活動鏈接。

程式碼環境

原始碼主要laravel5.8,一整​​個活動要貼的程式碼很多,以下主要貼核心程式碼,僅供參考。主要還是要根據自己的業務需求來實現功能吧。

以下是後端截圖,做成模組化

#前端需要做的設定與限制:

1 判斷優惠券是否存在或停用
2 判斷活動開始時間與優惠券開始時間

接著領取活動優惠券,需要判斷以下情況:
1 活動已結束
2 活動為開始時
3 活動為新用戶領取,而領取的用戶是老用戶
4 活動為老用戶領取,而領取的用戶是新用戶
5 優惠券是否領取完
6 已領取過優惠券提示
7 領取成功

#下面核心代碼實現

/**
