1. What is cashback

Cashback means that merchants give consumers a certain amount of rebate after they complete specified behaviors. This designated behavior can be a series of behaviors such as purchasing goods, consuming, participating in activities, etc. The advantage of cashback is that it can stimulate consumers' desire to consume and at the same time increase merchants' sales.

1. Database design

Before implementing the cashback function, we need to design the database first. Usually we need to store cashback data in the database. The database needs to include at least the following tables:

(1) User table

The user table contains the user's personal information, including ID, user name, password, mobile phone number, etc.

(2) Product table

The product table contains product-related information, including product ID, product name, product price, etc.

(3) Order table

The order table contains information related to the order, including order ID, total order amount, order time, user ID, etc.

(4) Cashback table

The cashback table contains cashback related information, including cashback ID, cashback amount, cashback time, etc.

2. Implementation of cashback function

There are many specific ways to implement cashback. Here we take full discount as an example to illustrate. When a user purchases goods, when the order amount reaches a certain amount, the system will automatically return part of the amount to the user.

(1) Add cashback information to the product details page

Add cashback information to the product details page, which usually displays the cashback activities that the product enjoys and the amount of cashback and other information.

(2) Calculation of cashback information

On the order page, the cashback amount needs to be calculated. Generally, the cashback amount is directly proportional to the order amount. The larger the order amount, the greater the cashback amount. After calculating the total order amount, we can calculate the cash rebate amount based on different conditions.

(3) Storage of cashback information

After the user successfully places an order, the order information will be stored in the order table. At the same time, the system will also store cashback information in the cashback table, including cashback ID, cashback amount, cashback time and other information.

(4) Cashback issuance

When the order is completed, the system will calculate the actual cashback amount based on the order amount and cashback rules. The cashback amount will be returned to the user's account balance within a certain period of time. Users can check their account balance and cashback details at any time.

3. Setting of cashback rules

In order to ensure the correctness and fairness of the cashback function, we need to formulate some cashback rules in advance. These include the following aspects:

(1) The proportional relationship between the cash rebate amount and the order amount. Generally, the cashback amount is directly proportional to the order amount.

(2) Upper limit of cash rebate amount. Under normal circumstances, there will be a certain upper limit on the amount of cash back to avoid excessive business operations.

(3) Cashback time. Cashback needs to be carried out within a certain period of time to ensure that users can use the cashback amount in time.

4. Security measures

The cashback function usually involves important information such as user accounts and balances, so the security protection measures of the system must be strengthened. It is recommended to test the interface security before implementing the cashback function, and set the API to be open only to authorized users.

3. Summary

The above are the main methods and precautions for implementing the cashback function in PHP. As a powerful development language, PHP can provide many useful functions for enterprises.
