How to use PHP Developer City to realize the coupon activity rule management function

With the development of e-commerce, mall websites have become one of the main ways for people to shop. In order to attract more users, merchants have adopted a variety of promotional activities, such as coupon activities. The coupon activity is to issue coupons to users, so that users can get certain discounts when purchasing goods, thereby increasing users' enthusiasm for purchasing. This article will introduce how to use PHP Developer City to implement the coupon activity rule management function.

1. Design database table structure

Before developing any functions, you first need to design the database. In this case, we need to design two tables: one is the coupon table, used to store coupon-related information; the other is the rule table, used to store the rules of each coupon activity.

The fields of the coupon table can include: coupon ID, coupon name, coupon amount, coupon validity period, etc.

The fields of the rule table can include: rule ID, rule name, rule type, rule content, etc.

2. Develop coupon activity rule management page

In PHP, we can use HTML CSS to develop the page. Develop a coupon activity rule management page that lists the current activity rules in a table and provides add, edit, and delete functions.

3. Develop the function of adding rules

The function of adding rules mainly includes the following steps:

(1) Create a form for adding rules for Enter information about the rule.

(2) Use the POST method in PHP to receive the data submitted by the form.

(3) Verify the received data to ensure that the input data meets the requirements.

(4) Insert the verified data into the rule table and save the new rule.

4. Develop the edit rule function

The edit rule function mainly includes the following steps:

(1) On the rule list page, for each rule Add edit button.

(2) After clicking the edit button, it will jump to the page for editing rules and display the current rule information.

(3) In the edit page, users can modify the relevant information of the rules.

(4) Use the POST method in PHP to receive the data submitted by the form and verify the received data.

(5) Update the verified data to the rule table and save the modified rules.

5. Develop the delete rule function

The delete rule function mainly includes the following steps:

(1) On the rule list page, for each rule Add delete button.

(2) After clicking the delete button, a confirmation box pops up asking the user to confirm the deletion.

(3) Based on the user’s confirmation, use PHP code to delete the corresponding rules.

6. Logical control of coupon activities

In the actual mall operation process, there may be some restrictions on the use of coupon activities, such as each user can only Use a coupon, or you can only use a coupon if you meet a certain purchase amount, etc. In order to realize these logical controls, we can use the PHP code to determine whether the user complies with the coupon usage rules during shopping checkout, thereby deciding whether to reduce or reduce the corresponding amount.

Through the above steps, we can use the PHP Developer City coupon activity rule management function. Using the rule table, you can easily add, edit and delete rules, and flexibly control different coupon activities. At the same time, through logic control, more refined coupon usage rules can be implemented to improve user shopping experience.
