PHP Mall Development Example: Design and Implementation of Coupons

Introduction:
With the rapid development of the e-commerce industry, coupons are used as a promotional tool It is widely used in various e-commerce platforms. Coupons, with their convenience and flexibility, have become an effective way to attract users and increase sales. This article will be based on a PHP mall development example to introduce the design and implementation of coupons to help readers understand the basic concepts of coupons and how to implement the coupon function in the mall system.

1. The basic concept of coupons
A coupon is a consumption coupon with a specific denomination or a specific discount ratio. By using the coupon, users can enjoy preferential policies such as product discounts and full discounts. Coupons can be divided into different types such as cash coupons, discount coupons, and discount coupons. In the mall system, users can enter or select the coupon code during shopping settlement, and the system will automatically calculate the actual payment amount after the discount.

2. Database design of coupons
In the mall system, in order to realize the function of coupons, we need to design the corresponding database table structure. The following is an example of a simplified coupon table:

  1. coupon table
    Fields:
  2. id: Coupon ID, primary key
  3. code: Coupon Code, unique index
  4. type: Coupon type, such as cash coupons, discount coupons, discount coupons, etc.
  5. value: coupon face amount or discount ratio
  6. condition: discount The usage conditions of the coupon, such as the amount of money that can be used
  7. expire_date: the validity period of the coupon
  8. user_coupon table
    field:
  9. id: user coupon ID, primary key
  10. user_id: User ID, foreign key is associated with the user table
  11. coupon_id: Coupon ID, foreign key is associated with the coupon table
  12. used: Whether the coupon has been used
  13. used_date: Coupon usage time

Through the design of the above two tables, we can save the basic information of the coupon, and also record the relevant information of the user receiving and using the coupon.

3. Implementation of the coupon function
Next, we will implement the coupon function in the PHP mall development example.

  1. Issue of Coupons
    The mall system can issue coupons during user registration, user's first purchase or during specific activities. Insert the corresponding coupon record in the database and send the coupon code to the user.
  2. Receive coupons
    Users can receive coupons by entering the coupon code or clicking the receive button on the page. Insert records into the user_coupon table to associate users and coupons.
  3. Use of coupons
    Users can choose whether to use coupons when shopping and settling. The mall system searches for the corresponding coupon record in the database based on the coupon code selected by the user. According to the type and conditions of the coupon, the actual payment amount is calculated, and the usage status and usage time in the user_coupon table are updated.
  4. Expiration processing of coupons
    The mall system needs to regularly check the expiration time of coupons, set expired coupons to an invalid state, and update the corresponding database records.

Conclusion:
Through the introduction of this article, we have learned about the basic concepts and database design of coupons, as well as the method of implementing the coupon function in a PHP mall development example.
