How to implement online community forums through WebMan technology

With the rapid development of the Internet, community forums have become an important platform for people to communicate, share and obtain information. WebMan technology provides developers with a solution to quickly and efficiently build online community forums. This article will introduce how to implement a simple online community forum through WebMan technology and provide code samples for reference.

1. Preparation
Before starting development, we need to prepare a development environment, including Web server, database and development tools. For web servers, we can use common server software such as Apache and Nginx; for databases, we can choose relational databases such as MySQL and PostgreSQL; as for development tools, we can use text editors or IDEs, such as Sublime Text, Visual Studio Code, etc. .

2. Build the basic framework

Create database
Create a database named "forum" in the MySQL database, and create the following two tables: users and posts.

The users table contains the following fields:

id: user ID (primary key, auto-increment)
username: user name
password: Password

The posts table contains the following fields:

id: Post ID (primary key, auto-increment)
title: Post title
content: Post content
user_id: The user ID of the poster

Create a Web project folder
Create a file named "forum" folder, and create the following files and folders in it:
index.php: Entry file to enter the forum homepage
login.php: Login page
register.php: Registration page
forum.php: Forum homepage
css folder: Store style sheet files
js folder: Store JavaScript files

3. Write code

index.php

<!DOCTYPE html>
<html>
<head>
  <title>在线社区论坛</title>
  <link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
  <h1>欢迎来到在线社区论坛！</h1>
  <a href="login.php">登录</a>
  <a href="register.php">注册</a>
</body>
</html>

Copy after login

<!DOCTYPE html>

<head>
  <title>登录</title>
  <link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
  <h1>登录</h1>
  <form action="login.php" method="post">
    <label for="username">用户名：</label>
    <input type="text" name="username"><br>
    <label for="password">密码：</label>
    <input type="password" name="password"><br>
    <input type="submit" value="登录">
  </form>
</body>
</html>

Copy after login

<!DOCTYPE html>
<html>
<head>
  <title>注册</title>
  <link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
  <h1>注册</h1>
  <form action="register.php" method="post">
    <label for="username">用户名：</label>
    <input type="text" name="username"><br>
    <label for="password">密码：</label>
    <input type="password" name="password"><br>
    <input type="submit" value="注册">
  </form>
</body>
</html>

Copy after login

forum.php

<!DOCTYPE html>
<html>
<head>
  <title>论坛</title>
  <link rel="stylesheet" type="text/css" href="css/style.css">
</head>
<body>
  <h1>论坛</h1>
  <a href="logout.php">退出</a>
  <h2>发帖</h2>
  <form action="post.php" method="post">
    <label for="title">标题：</label>
    <input type="text" name="title"><br>
    <label for="content">内容：</label>
    <textarea name="content"></textarea><br>
    <input type="submit" value="发表">
  </form>
  <h2>帖子列表</h2>
  <?php
    // 获取帖子列表并显示
    $conn = mysqli_connect("localhost", "root", "password", "forum");
    $result = mysqli_query($conn, "SELECT * FROM posts");
    while ($row = mysqli_fetch_array($result)) {
      echo "<h3>" . $row['title'] . "</h3>";
      echo "<p>" . $row['content'] . "</p>";
    }
    mysqli_close($conn);
  ?>
</body>
</html>

Copy after login

4. Run the program

and save the above code to the corresponding file , and placed in the correct folder.
Enter the server address in the browser, such as "http://localhost/forum/index.php", to enter the forum homepage.
Click "Login" to enter the login page, enter your username and password and click the "Login" button.
If you log in successfully, you will be redirected to the forum homepage, where you can post new posts through the "Post" form. A list of posts will appear on the page.
