How to use PHP developer mall to implement user points query function

With the continuous development of e-commerce, more and more merchants have begun to introduce the points system into their own malls to improve user loyalty. and purchase intention. Using PHP to develop a city and realize the user points query function is an urgent need for merchants.

Before we start to discuss how to implement the user points query function, we first need to understand how user points are generated and managed in a mall system. Normally, the mall system maintains a user table that contains the points information of each user. When a user completes an order, the system will calculate the points the user deserves based on the order amount and add the points to the user's total points. At the same time, after the user confirms receipt of the goods, the system will convert points into cash based on a certain proportion of the order amount. Users can view their points balance and points redemption records on the personal center page after logging in.

Next, let’s take a look at how to use the PHP Developer City to implement the user points query function.

First, we need to add a field to the user table to save the user's total points, for example, it is called credit. The type of this field can be selected as integer or floating point, depending on the actual situation. After the user completes the order and confirms receipt, we need to write corresponding business logic to update the user's total points.

Next, on the personal center page after the user logs in, we can add a link or button to the page to jump to the points query page. In PHP, we can use hyperlinks or forms to achieve this function. When the user clicks the link or button, we can use a PHP script to process the logic of user points query.

In this PHP script, we first need to verify the user's identity to ensure that the user is logged in. If the user is not logged in or authentication fails, we can jump to the login page or return an error message.

Next, we can obtain the user's total points and points redemption records by querying the user table. In PHP, we can use MySQL or other databases to store and manage user points information. By executing the corresponding SQL statement, we can obtain the user's total points and points redemption record from the database and display them on the page.

Finally, we can add some additional functions to the query results page, such as displaying the user's points consumption and redemption rules. These features help increase user points engagement and activity.

It should be noted that during the development process, we need to consider the security of user input and control of access rights to the database. Use PHP's filter functions to filter user input to prevent SQL injection and other security vulnerabilities.

To sum up, it is not difficult to use PHP to develop a city and realize the user points query function. Through reasonable design and coding, we can easily implement this function and provide a good user experience for users in the mall system. I hope this article can help you implement the user points query function.
