How to use PHP to implement the online customer service function of the CMS system

1. Overview
With the rapid development of the Internet, more and more companies have built their websites into an important marketing channel, and Attract customers, conduct sales and service through the website. In order to provide a better user experience and enhance user stickiness, many companies have added online customer service functions to their websites to facilitate users to communicate with customer service staff instantly when visiting the website. This article will introduce how to use PHP to implement a simple online customer service function.

2. Preparation work
Before we start writing code, we need to prepare the following work:

A server environment that supports PHP, such as Apache or Nginx.
A MySQL database to store customer service chat records.
A CMS system that contains the necessary files, such as WordPress.

3. Database design
We first need to create a database to store customer service chat records. Create a table named "chat_records", containing the following fields:

id: auto-incrementing primary key.
user_id: User ID.
staff_id: Customer service staff ID.
message: Chat content.
created_at: Record creation time.

4. Code Implementation

Create database connection
We first need to create a database connection, you can create one named "db.php" file with the following content:

<?php
$host = "localhost"; //数据库地址
$dbname = "your_db_name"; //数据库名称
$username = "your_username"; //数据库用户名
$password = "your_password"; //数据库密码

try {
 $db = new PDO("mysql:host=$host;dbname=$dbname", $username, $password);
 $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
 echo "数据库连接失败: " . $e->getMessage();
}
?>

Replace "your_db_name", "your_username" and "your_password" with your database name, username and password.

Create a message sending page
We can create a page named "send_message.php" for the client to send messages to the server. The content is as follows:

<?php
if(isset($_POST['message']) && !empty($_POST['message'])) {
 $message = $_POST['message'];
 $user_id = $_POST['user_id'];
 $staff_id = $_POST['staff_id'];

 // 在此处将消息存入数据库

 echo "消息已发送";
} else {
 echo "发送失败";
}
?>

Create message receiving page
We can create a page named "receive_message.php" for the server to receive messages and store them in the database. The content is as follows:

<?php
if(isset($_POST['message']) && !empty($_POST['message'])) {
 $message = $_POST['message'];
 $user_id = $_POST['user_id'];
 $staff_id = $_POST['staff_id'];

 // 在此处将消息存入数据库

 echo "消息已接收";
} else {
 echo "接收失败";
}
?>

Update CMS system
In our CMS system, we need to create a page to display the online customer service function. We can create a page named "chat.php" and add the following code to the page:

<?php
session_start();

if(isset($_SESSION['user_id']) && isset($_SESSION['staff_id'])) {
 $user_id = $_SESSION['user_id'];
 $staff_id = $_SESSION['staff_id'];
} else {
 // 用户未登录，默认使用一个用户ID和一个客服人员ID
 $user_id = 1;
 $staff_id = 1;
}

require_once("db.php");

// 获取聊天记录
$query = $db->prepare("SELECT * FROM chat_records WHERE (user_id = :user_id AND staff_id = :staff_id) OR (user_id = :staff_id AND staff_id = :user_id) ORDER BY created_at ASC");
$query->bindParam(':user_id', $user_id);
$query->bindParam(':staff_id', $staff_id);
$query->execute();

$chat_records = $query->fetchAll(PDO::FETCH_ASSOC);
?>

<!DOCTYPE html>
<html>
<head>
 <title>在线客服</title>
 <!-- 加入其他相关的样式和JavaScript文件 -->
</head>
<body>
 <!-- 在此处添加你的页面结构代码 -->
 
 <div id="chatBox">
     <?php foreach($chat_records as $record): ?>
         <div class="<?php echo ($record['user_id'] == $user_id ? 'user' : 'staff'); ?>">
             <?php echo $record['message']; ?>
         </div>
     <?php endforeach; ?>
 </div>

 <form id="messageForm">
     <input type="hidden" name="user_id" value="<?php echo $user_id; ?>">
     <input type="hidden" name="staff_id" value="<?php echo $staff_id; ?>">
     <input type="text" name="message" placeholder="请输入消息">
     <button type="submit">发送</button>
 </form>

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
 <script>
     $(document).ready(function() {
         $("#messageForm").submit(function(e) {
             e.preventDefault();

             var form = $(this);
             var url = form.attr("action");

             $.ajax({
                 type: "POST",
                 url: url,
                 data: form.serialize(),
                 success: function(data) {
                     console.log(data); // 输出服务端返回的信息
                     
                     // 在此处可以进行一些界面刷新或其他处理
                     
                     form[0].reset(); // 清空输入框
                 }
             });
         });
     });
 </script>
 <!-- 加入其他相关的JavaScript代码 -->
</body>
</html>

5. Summary
Through the above steps, we have completed a simple Implementation of online customer service function. Users can chat with customer service staff in real time by accessing the "chat.php" page, and the chat records will be saved in the database. You can extend and optimize the code according to your needs. This is just an example, you can implement more complex and complete functions according to your specific needs.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
