数据库设计

主要数据表结构:

-- 用户表
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50) UNIQUE NOT NULL,
    email VARCHAR(100) UNIQUE NOT NULL,
    password_hash VARCHAR(255) NOT NULL,
    role ENUM('admin', 'editor', 'user') DEFAULT 'user',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

-- 博客文章表
CREATE TABLE posts (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    title VARCHAR(255) NOT NULL,
    slug VARCHAR(255) UNIQUE NOT NULL,
    content TEXT NOT NULL,
    excerpt TEXT,
    status ENUM('published', 'draft', 'trash') DEFAULT 'draft',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    published_at TIMESTAMP NULL,
    FOREIGN KEY (user_id) REFERENCES users(id)
);

-- 论坛主题表
CREATE TABLE topics (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    title VARCHAR(255) NOT NULL,
    content TEXT NOT NULL,
    category_id INT NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id),
    FOREIGN KEY (category_id) REFERENCES categories(id)
);

-- 评论表
CREATE TABLE comments (
    id INT AUTO_INCREMENT PRIMARY KEY,
    user_id INT NOT NULL,
    content TEXT NOT NULL,
    parent_id INT NULL COMMENT '用于回复评论',
    post_id INT NULL COMMENT '关联博客文章',
    topic_id INT NULL COMMENT '关联论坛主题',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (user_id) REFERENCES users(id),
    FOREIGN KEY (post_id) REFERENCES posts(id),
    FOREIGN KEY (topic_id) REFERENCES topics(id)
);

-- 分类表
CREATE TABLE categories (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    slug VARCHAR(100) UNIQUE NOT NULL,
    description TEXT,
    type ENUM('post', 'topic') NOT NULL
);

核心功能实现

1. 用户认证系统 (PHP)

// auth.php
session_start();

function registerUser($username, $email, $password) {
    // 验证输入
    // 检查用户名/邮箱是否已存在
    // 密码哈希处理
    $password_hash = password_hash($password, PASSWORD_DEFAULT);
    
    // 数据库插入
    $stmt = $pdo->prepare("INSERT INTO users (username, email, password_hash) VALUES (?, ?, ?)");
    return $stmt->execute([$username, $email, $password_hash]);
}

function loginUser($username, $password) {
    $stmt = $pdo->prepare("SELECT * FROM users WHERE username = ?");
    $stmt->execute([$username]);
    $user = $stmt->fetch();
    
    if ($user && password_verify($password, $user['password_hash'])) {
        $_SESSION['user_id'] = $user['id'];
        $_SESSION['username'] = $user['username'];
        $_SESSION['role'] = $user['role'];
        return true;
    }
    return false;
}

function isLoggedIn() {
    return isset($_SESSION['user_id']);
}

function isAdmin() {
    return isset($_SESSION['role']) && $_SESSION['role'] === 'admin';
}

2. 博客系统 (PHP + MySQL)

// posts.php
function createPost($userId, $title, $content, $status = 'draft') {
    $slug = createSlug($title);
    $excerpt = substr(strip_tags($content), 0, 200);
    
    $stmt = $pdo->prepare("INSERT INTO posts 
        (user_id, title, slug, content, excerpt, status, published_at)
        VALUES (?, ?, ?, ?, ?, ?, ?)");
    
    $publishedAt = $status === 'published' ? date('Y-m-d H:i:s') : null;
    
    return $stmt->execute([
        $userId, $title, $slug, $content, $excerpt, $status, $publishedAt
    ]);
}

function getPosts($page = 1, $perPage = 10) {
    $offset = ($page - 1) * $perPage;
    $stmt = $pdo->prepare("SELECT * FROM posts 
        WHERE status = 'published' 
        ORDER BY published_at DESC 
        LIMIT ? OFFSET ?");
    $stmt->bindValue(1, $perPage, PDO::PARAM_INT);
    $stmt->bindValue(2, $offset, PDO::PARAM_INT);
    $stmt->execute();
    return $stmt->fetchAll();
}

function getPostBySlug($slug) {
    $stmt = $pdo->prepare("SELECT p.*, u.username 
        FROM posts p 
        JOIN users u ON p.user_id = u.id 
        WHERE p.slug = ? AND p.status = 'published'");
    $stmt->execute([$slug]);
    return $stmt->fetch();
}

3. 前端AJAX交互 (JavaScript)

// main.js
document.addEventListener('DOMContentLoaded', function() {
    // 评论提交
    document.getElementById('comment-form').addEventListener('submit', function(e) {
        e.preventDefault();
        
        const formData = new FormData(this);
        const postId = this.dataset.postId;
        
        fetch('/api/comments', {
            method: 'POST',
            body: JSON.stringify({
                post_id: postId,
                content: formData.get('content')
            }),
            headers: {
                'Content-Type': 'application/json',
                'X-CSRF-TOKEN': document.querySelector('meta[name="csrf-token"]').content
            }
        })
        .then(response => response.json())
        .then(data => {
            if (data.success) {
                // 更新评论列表
                loadComments(postId);
                this.reset();
            }
        });
    });
    
    // 加载评论
    function loadComments(postId) {
        fetch(`/api/posts/${postId}/comments`)
            .then(response => response.json())
            .then(comments => {
                const container = document.getElementById('comments-container');
                container.innerHTML = comments.map(comment => `
                    <div class="comment">
                        <div class="comment-author">${comment.username}</div>
                        <div class="comment-content">${comment.content}</div>
                        <div class="comment-date">${new Date(comment.created_at).toLocaleString()}</div>
                    </div>
                `).join('');
            });
    }
});

4. 响应式设计 (CSS)

/* styles.css */
:root {
    --primary-color: #3498db;
    --secondary-color: #2ecc71;
    --dark-color: #2c3e50;
    --light-color: #ecf0f1;
}

/* 基础布局 */
.container {
    width: 100%;
    max-width: 1200px;
    margin: 0 auto;
    padding: 0 15px;
}

/* 导航栏 */
.navbar {
    background-color: var(--dark-color);
    color: white;
    padding: 1rem 0;
}

.navbar .container {
    display: flex;
    justify-content: space-between;
    align-items: center;
}

/* 文章卡片 */
.post-card {
    border: 1px solid #ddd;
    border-radius: 5px;
    margin-bottom: 2rem;
    overflow: hidden;
    transition: transform 0.3s ease;
}

.post-card:hover {
    transform: translateY(-5px);
    box-shadow: 0 5px 15px rgba(0,0,0,0.1);
}

/* 响应式设计 */
@media (max-width: 768px) {
    .navbar .container {
        flex-direction: column;
    }
    
    .post-list {
        grid-template-columns: 1fr;
    }
}

/* 论坛主题样式 */
.topic {
    padding: 1rem;
    border-bottom: 1px solid #eee;
}

.topic-title {
    font-size: 1.2rem;
    color: var(--primary-color);
    margin-bottom: 0.5rem;
}

.topic-meta {
    font-size: 0.8rem;
    color: #777;
}
