PHP mall development tutorial: teach you step by step how to implement the coupon function

With the continuous development of the Internet, e-commerce has become one of the main ways for people to shop. In e-commerce, the development of mall websites is particularly important. Among them, the coupon function, as a marketing tool to attract consumers, has also become one of the necessary functions in the development of mall websites. This article will teach you step by step how to implement the coupon function through a PHP mall development tutorial.

1. Determine the requirements and design of the coupon function

Before developing the coupon function, we first need to clarify the requirements and design of the function. Coupon functions generally include the generation, collection, use and expiration of coupons.

For the generation of coupons, different types of coupons can be generated according to the merchant's setting rules. For example, you can get 10 yuan off for purchases over 100 yuan or discounts for purchases over 200 yuan.

The process of receiving coupons can be done by the user clicking the receive button to add the coupon to the user's account.

During product settlement, users can choose to use the received coupons for deduction.

Expiration processing is to clean up expired coupons, and the system will automatically delete expired coupons from the user account.

2. Database table design

The development of the coupon function cannot be separated from the support of the database. We need to design corresponding database tables to store coupon-related data.

For example, we can design a coupon table to save coupon information, including the coupon's name, face value, usage conditions, expiration time and other fields.

In addition, we also need to design a user_coupon table to associate users and coupons. In this table, we can save the user ID and the corresponding coupon ID.

3. Generation and collection of coupons

In code implementation, we can generate coupons by writing a generateCoupon function. This function generates corresponding coupons based on the merchant's setting rules and saves them to the coupon table.

For the coupon collection process, we can provide users with a collection page, where users can click the receive button to add coupons to their accounts. After the user clicks the claim button, the PHP code can insert the corresponding coupon ID and user ID into the user_coupon table.

4. Use of coupons

In the settlement page, we can query the user_coupon table by obtaining the user ID to obtain the coupon information that the user has received. Users can choose to use the coupons for discounts.

After the settlement is completed, we also need to update the data in the coupon table and user_coupon table to update the used coupon status.

5. Coupon Expiration Processing

Scheduled tasks are a common way to implement coupon expiration processing. We can write a script and set up scheduled tasks to automatically detect and delete expired coupons.

In the script, we can determine whether the coupon has expired by querying the expiration time field in the coupon table. If it expires, delete the corresponding record.

6. Front-end display and interaction

When developing the coupon function, front-end display and interaction cannot be ignored. We can design a simple and clear interface to display the coupons that users have received and provide corresponding operation buttons.

Through front-end frameworks such as jQuery, we can realize interactive operations such as coupon collection, use and deletion. For example, after the user clicks the claim button, the data can be sent to the backend through Ajax request to realize the coupon collection function.

Through the implementation of the above steps, we can complete a basic coupon function. In actual development, we can also expand and optimize according to actual needs, such as increasing the scope of use, limiting the number of uses, and other functions.

In short, through this PHP mall development tutorial, we can master the method of realizing the coupon function and provide a powerful marketing tool for the development of mall websites. At the same time, this is also an important way to improve user experience and promote sales growth. I hope this article can be helpful to PHP developers and better implement the coupon function.
