PHP Mall Development Guide: How to Add Coupon Function

In today’s e-commerce era, coupons have become one of the important means for major e-commerce platforms to attract users. As a kind of promotional activity, coupons can help merchants increase sales and improve user stickiness, while also allowing consumers to enjoy more benefits. In PHP mall development, how to add coupon function has become a very important topic. This article will introduce how to add coupon function in PHP mall.

First of all, we need to clarify the types and rules of coupons. Generally speaking, coupons can be divided into two types: discount coupons and full discount coupons. Discount coupons can reduce the order amount according to a certain discount ratio, while full discount coupons can reduce the specified amount after the order amount meets certain conditions. In actual development, we can define more coupon types according to business needs. At the same time, according to different usage rules, we can set the validity period of the coupon, the scope of participating products and usage restrictions, etc.

Next, we need to establish a corresponding table structure in the database to store coupon information. Generally speaking, a coupon table, coupon user table and order table need to be established to store relevant data. The coupon table needs to store basic information about coupons, such as coupon name, coupon type, discount ratio, full discount amount, usage restrictions, etc. The coupon user table is used to record the user's receipt and use of coupons. It can also record the status and expiration time of the coupon. The order table is used to record information related to the user's order, including the coupon information used.

In the PHP mall development process, we can use frameworks such as Laravel to simplify the development process. First, we need to define the coupon model and order model in the model, and establish the relationship between the models. In the coupon model, we can define some query scopes to query coupon information based on different conditions. In the order model, by defining the association relationship, the coupon information corresponding to the order can be easily obtained.

Next, we need to write corresponding methods in the controller to handle the logic of receiving and using coupons. In the method of receiving coupons, we need to first determine whether the user meets the conditions for receiving the coupon, such as whether he is a new user or whether he meets the time limit for receiving the coupon. If the user meets the conditions for receiving it, we can insert a record into the coupon user table and set the coupon to the received status. In the method of using coupons, we need to first determine whether the coupon is available, that is, whether it meets the conditions for use, such as whether the order amount meets the full discount amount or discount ratio, etc. If a coupon is available, we can record the coupon information in the order table and update the order amount.

Finally, add the corresponding coupon collection and use functions to the front-end page. We can add a button to receive coupons on the product details page or shopping cart page, and add a selection box to use coupons on the order confirmation page. In the background management page, we can add coupon management functions, including adding, editing and deleting coupons.

In actual development, we can also combine other functions to improve the coupon usage experience. For example, you can receive a coupon by default when the user logs in or registers, or automatically use the corresponding coupon when the user purchases specified products. In addition, we can also send coupons to users via email or text messages to remind users to use coupons, etc.

To sum up, adding coupon function is a very important part of PHP mall development. By rationally designing the table structure, writing corresponding logic code and page functions, we can realize the function of receiving and using coupons, thereby improving user shopping experience, increasing user stickiness, and promoting sales. I believe that in the future development of shopping malls, the coupon function will become more and more important and become one of the essential functions of major e-commerce platforms.
