How to use PHP to implement the article publishing function of the CMS system

With the rapid development of the Internet, the content management system (CMS) has become an indispensable part of website development. The article publishing function is one of the most common functions in CMS systems. This article will introduce how to use PHP language to implement the article publishing function of CMS system, and come with code examples.

1. Database design

Before you start writing PHP code, you first need to design a database table to store relevant information about the article. The following is a simple article table design:

文章表(article)：
- id：文章ID，主键自增
- title：文章标题
- content：文章内容
- author：文章作者
- create_time：文章创建时间

2. Create an article publishing page

In a CMS system, there is usually a background management page to publish and manage articles. We can create a file named "publish_article.php" to implement the article publishing function.

First, we need to create an HTML form to receive the title, content and author of the article. The code example is as follows:

<form action="publish_article.php" method="POST">
   <label for="title">标题:</label>
   <input type="text" id="title" name="title"><br><br>
   <label for="content">内容:</label><br>
   <textarea id="content" name="content" rows="10" cols="50"></textarea><br><br>
   <label for="author">作者:</label>
   <input type="text" id="author" name="author"><br><br>
   <input type="submit" value="发布">
</form>

Next, we need to write PHP code to process the form data and insert the article into the database. The code example is as follows:

<?php
   // 连接数据库
   $conn = new mysqli("localhost", "username", "password", "database_name");
   if ($conn->connect_error) {
      die("连接失败: " . $conn->connect_error);
   }
   
   // 获取表单数据
   $title = $_POST['title'];
   $content = $_POST['content'];
   $author = $_POST['author'];
   
   // 构建SQL插入语句
   $sql = "INSERT INTO article (title, content, author, create_time) VALUES ('$title', '$content', '$author', NOW())";
   
   // 执行插入操作
   if ($conn->query($sql) === TRUE) {
      echo "文章发布成功！";
   } else {
      echo "发布失败: " . $conn->error;
   }
   
   // 关闭数据库连接
   $conn->close();
?>

3. Improve the article list display function

In addition to publishing articles, we usually also need to display the published article list. We can create a file named "article_list.php" to display the article list. The code example is as follows:

<?php
   // 连接数据库
   $conn = new mysqli("localhost", "username", "password", "database_name");
   if ($conn->connect_error) {
      die("连接失败: " . $conn->connect_error);
   }
   
   // 查询所有文章
   $sql = "SELECT * FROM article";
   $result = $conn->query($sql);
   
   // 输出文章列表
   if ($result->num_rows > 0) {
      while($row = $result->fetch_assoc()) {
         echo "标题: " . $row["title"]. " - 作者: " . $row["author"]. " - 创建时间: " . $row["create_time"]. "<br>";
      }
   } else {
      echo "暂无文章";
   }
   
   // 关闭数据库连接
   $conn->close();
?>

4. Add security measures

When implementing the article publishing function, we also need to consider security. The following measures can be taken to enhance security:

1. Filter user-entered data to prevent SQL injection attacks. Use the mysqli_real_escape_string() function or parameter binding to escape user-entered data.
2. Verify the content entered by the user to ensure legality. For example, limit the length of article titles and authors to prevent users from entering too long content.
3. Add form validation function to ensure that the content entered by the user meets the requirements. For example, perform non-null validation on title and author.

Summary:

Through the above steps, we can use PHP language to implement the article publishing function of the CMS system. First, design a database table to store article information. Then, create an article publishing page and an article list display page, and write corresponding PHP code to implement the functions. At the same time, add some security measures to protect the system from attacks.
