Building a PHP mall: Creating a user feedback and after-sales service system

With the rapid development of e-commerce, user feedback and after-sales service have become an important part of any mall operation. In this article, we will learn how to build a simple yet powerful user feedback and after-sales service system using PHP language.

1. Database design

First, we need to create a database to store user feedback information and after-sales service records. We can use MySQL or other relational databases. The following is a simple database schema example:

CREATE TABLE feedback (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT,
    message TEXT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

CREATE TABLE support_tickets (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT,
    subject VARCHAR(255),
    message TEXT,
    status ENUM('open', 'closed', 'resolved') DEFAULT 'open',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

In this schema, we have two tables. The feedback table is used to store user feedback information, including user ID, feedback content and creation time. The support_tickets table is used to store after-sales service records, including user ID, subject, message, status and creation time.

2. Create user feedback page

In the mall, we can add a feedback page for users so that users can easily provide feedback. Here is a simple example of a user feedback page:

<form action="submit_feedback.php" method="post">
    <textarea name="message" rows="5" cols="50"></textarea>
    <input type="submit" value="Submit Feedback">
</form>

In this example, we use a form to let the user enter feedback information and send the information to the submit_feedback.php page via a POST request.

3. Handling user feedback requests

In the submit_feedback.php page, we need to process the feedback information and save it to the database. The following is a simple PHP code example:

<?php
// 获取用户输入
$message = $_POST['message'];

// 验证输入是否为空
if(empty($message)) {
    echo "请填写反馈内容";
    exit;
}

// 将反馈信息保存到数据库
$conn = mysqli_connect('localhost', 'username', 'password', 'database');
$query = "INSERT INTO feedback (user_id, message) VALUES ('$user_id', '$message')";
mysqli_query($conn, $query);

echo "感谢您的反馈！";
?>

In this example, we first obtain the feedback information entered by the user. Then we verify that the input is empty. Finally, we insert the feedback information into the feedback table.

4. Create an after-sales service page

In addition to user feedback, the mall should also provide an after-sales service page to facilitate users to submit after-sales service requests. The following is a simple after-sales service page example:

<form action="submit_support_ticket.php" method="post">
    <input type="text" name="subject" placeholder="主题">
    <textarea name="message" rows="5" cols="50"></textarea>
    <input type="submit" value="Submit Ticket">
</form>

In this example, we use a form to allow users to enter the subject and message of the after-sales service request.

5. Processing after-sales service requests

In the submit_support_ticket.php page, we need to process after-sales service requests and save them to the database. The following is a simple PHP code example:

<?php
// 获取用户输入
$subject = $_POST['subject'];
$message = $_POST['message'];

// 验证输入是否为空
if(empty($subject) || empty($message)) {
    echo "请填写主题和消息";
    exit;
}

// 将售后服务请求保存到数据库
$conn = mysqli_connect('localhost', 'username', 'password', 'database');
$query = "INSERT INTO support_tickets (user_id, subject, message) VALUES ('$user_id', '$subject', '$message')";
mysqli_query($conn, $query);

echo "您的售后服务请求已提交！";
?>

In this example, we first get the subject and message of the after-sales service request entered by the user. Then we verify that the input is empty. Finally, we insert the after-sales service request into the support_tickets table.

Summary:

Through the above steps, we successfully built a user feedback and after-sales service system for the PHP mall. Users can now easily provide feedback and submit after-sales service requests, while mall administrators can easily manage and respond to these messages through the database. This system can help the mall provide a better user experience and higher after-sales service quality.

I hope this article can help you understand how to use PHP to build a user feedback and after-sales service system, and provide some reference and guidance for your mall operations.
