How to use PHP Developer City to implement coupon usage restriction rules

Introduction:
With the rapid development of e-commerce, online malls have become a shopping choice for more and more users. In order to attract more users, merchants often issue coupons to provide users with discounts or other benefits. However, in order to improve the efficiency of the mall and rationally utilize coupon resources, merchants often need to impose restrictions on the use of coupons. This article introduces the implementation method of coupon usage restriction rules from the perspective of PHP developer mall.

1. Analyze requirements and design database

1. Determine the basic attributes of the coupon: such as coupon number, name, denomination, usage conditions, etc.
2. Design user table and user coupon table: The user table stores user information, and the user coupon table stores records of users receiving and using coupons.

2. Implement coupon collection

1. After users log in to the mall, they can browse and receive coupons in the coupon list.
2. When receiving a coupon, it is necessary to verify whether the user meets the conditions for receiving the coupon, such as purchasing a certain amount, reaching a certain level, etc.
3. After receiving the coupon, insert the coupon information into the user coupon table for subsequent use.

3. Implement the use of coupons

1. Users can choose to use coupons when checking out the shopping cart.
2. When using a coupon, you need to verify whether the coupon is valid and meets the conditions for use.
3. If the coupon meets the usage conditions, the discount amount will be calculated and displayed in the order.
4. After using the coupon, update the usage status and usage time in the user's coupon table.

4. Implement coupon expiration processing

1. Write scheduled tasks or scripts to regularly check whether the coupons in the user's coupon table have expired.
2. If the coupon expires, update its status to expired status.

5. Implement coupon usage restriction rules
In order to control the usage scope and usage restrictions of coupons, the following methods can be used:

1. Restrict applicable products: in Add tags or categories to products in the mall, and set the scope of use of coupons to products with specific tags or categories.

5. Limit validity period: Set the validity period of the coupon. If it exceeds the validity period, it will be deemed invalid.

6. Summary
Through the above methods and implementation steps, we can use PHP to develop the mall and implement coupon usage restriction rules, thereby improving the efficiency of the mall and rationally utilizing coupon resources. During the development process, it is also necessary to reasonably design the database, write corresponding code logic and scheduled tasks to ensure the normal operation of the coupon system. At the same time, merchants need to continuously optimize and improve the rules for using coupons to enhance users’ shopping experience and the competitiveness of the mall.
