WordPress 分类标签页面浏览数统计

📊 实现方法对比

🔧 方法一：自定义字段法（最简单）

1.1 核心代码

// 添加到主题 functions.php
function count_category_views($category_id) {
    // 确保只在分类/标签页面执行
    if (!is_category() && !is_tag()) {
        return;
    }
    
    $current_id = 0;
    
    if (is_category()) {
        $current_id = get_queried_object_id();
    } elseif (is_tag()) {
        $current_id = get_queried_object_id();
    }
    
    if ($current_id) {
        $count_key = 'category_views_count';
        $count = get_term_meta($current_id, $count_key, true);
        
        if ($count == '') {
            $count = 0;
            delete_term_meta($current_id, $count_key);
            add_term_meta($current_id, $count_key, '1');
        } else {
            $count++;
            update_term_meta($current_id, $count_key, $count);
        }
    }
}
add_action('wp_head', 'count_category_views');

// 获取浏览数函数
function get_category_views($term_id) {
    $count = get_term_meta($term_id, 'category_views_count', true);
    return $count ? $count : 0;
}

// 显示浏览数短代码
function category_views_shortcode($atts) {
    $atts = shortcode_atts(array(
        'term_id' => 0,
        'label' => '浏览：',
        'show_icon' => true
    ), $atts);
    
    if (!$atts['term_id']) {
        if (is_category() || is_tag()) {
            $atts['term_id'] = get_queried_object_id();
        } else {
            return '';
        }
    }
    
    $views = get_category_views($atts['term_id']);
    $icon = $atts['show_icon'] ? '<i class="fas fa-eye"></i> ' : '';
    
    return '<span class="category-views">' . $icon . $atts['label'] . number_format($views) . '</span>';
}
add_shortcode('category_views', 'category_views_shortcode');

1.2 样式美化

/* 添加到主题样式表 */
.category-views {
    display: inline-block;
    padding: 5px 12px;
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
    color: white;
    border-radius: 20px;
    font-size: 13px;
    font-weight: 500;
    box-shadow: 0 4px 15px rgba(0, 0, 0, 0.1);
    transition: all 0.3s ease;
}

.category-views:hover {
    transform: translateY(-2px);
    box-shadow: 0 6px 20px rgba(0, 0, 0, 0.15);
}

.category-views i {
    margin-right: 5px;
    font-size: 12px;
}

🗃️ 方法二：数据库表法（最专业）

2.1 创建数据库表

// 创建统计表
function create_category_views_table() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'category_views';
    $charset_collate = $wpdb->get_charset_collate();
    
    $sql = "CREATE TABLE IF NOT EXISTS $table_name (
        id bigint(20) NOT NULL AUTO_INCREMENT,
        term_id bigint(20) NOT NULL,
        views_count bigint(20) NOT NULL DEFAULT 0,
        last_viewed datetime DEFAULT CURRENT_TIMESTAMP,
        PRIMARY KEY (id),
        UNIQUE KEY term_id (term_id),
        KEY views_count (views_count)
    ) $charset_collate;";
    
    require_once(ABSPATH . 'wp-admin/includes/upgrade.php');
    dbDelta($sql);
}
add_action('after_setup_theme', 'create_category_views_table');
register_activation_hook(__FILE__, 'create_category_views_table');

2.2 完整统计系统

    public function __construct() {

    // 追踪浏览
    public function track_view() {
        if (!is_category() && !is_tag()) {
            return;
        }
        
        $term_id = get_queried_object_id();
        
        // 检查是否已记录（防止刷新重复计数）
        if (!isset($_SESSION['viewed_categories'])) {
            $_SESSION['viewed_categories'] = array();
        }
        
        if (in_array($term_id, $_SESSION['viewed_categories'])) {

📱 移动端优化

6.1 响应式设计

/* 移动端优化样式 */
@media (max-width: 768px) {
    .popular-categories-cards {
        grid-template-columns: repeat(2, 1fr) !important;
        gap: 15px;
    }
    
    .category-card {
        padding: 15px;

🔍 SEO优化

7.1 Schema标记

// 添加Schema标记
function add_category_views_schema($term_id) {
    $views = get_category_views($term_id);
    $term = get_term($term_id);
    
    if ($views > 0) {
        $schema = array(
            '@context' => 'https://schema.org',
            '@type' => 'CollectionPage',
            'name' => $term->name,
            'description' => $term->description,
            'interactionStatistic' => array(
                '@type' => 'InteractionCounter',
                'interactionType' => 'https://schema.org/ViewAction',
                'userInteractionCount' => $views
            )
        );
        
        echo '<script type="application/ld+json">' . json_encode($schema) . '</script>';
    }
}
add_action('wp_head', function() {
    if (is_category() || is_tag()) {
        $term_id = get_queried_object_id();
        add_category_views_schema($term_id);
    }
});

🎯 最佳实践建议

统计策略

1. 避免重复计数：
   - 使用Session记录
   - AJAX延迟提交
   - 考虑IP限制

2. 性能优化：
   - 数据库索引优化
   - 定时缓存清理
   - 异步数据写入

3. 数据准确：
   - 排除爬虫访问
   - 排除管理员访问
   - 日志记录异常

部署建议

1. 新网站：使用方法一（简单）
2. 中型网站：使用方法二（完整）
3. 大型网站：插件+自定义
4. 高并发：Redis缓存+队列

📊 监控与分析

// 监控功能
function monitor_category_views() {
    global $wpdb;
    $table_name = $wpdb->prefix . 'category_views';
    
    // 监控异常增长
    $suspicious = $wpdb->get_results(
        "SELECT term_id, views_count, last_viewed
         FROM {$table_name}
         WHERE last_viewed >= DATE_SUB(NOW(), INTERVAL 1 HOUR)
         AND views_count > 1000
         ORDER BY views_count DESC
         LIMIT 10"
    );
    
    if ($suspicious) {
        // 发送警报
        wp_mail(
            get_option('admin_email'),
            '分类浏览异常警报',
            print_r($suspicious, true)
        );
    }
}
add_action('category_views_monitor', 'monitor_category_views');

// 定时执行
if (!wp_next_scheduled('category_views_monitor')) {
    wp_schedule_event(time(), 'hourly', 'category_views_monitor');
}

总结：选择适合您网站的统计方案，平衡功能需求和性能消耗。小型网站推荐方法一，中型网站推荐方法二，大型商业网站建议使用专业插件或定制开发。
