WordPress侧边栏添加信息统计

前言

刚刚写了一篇统计文章字数的文章，现在就教大家如何在侧边栏添加信息统计

教程

在子主题的function.php中添加如下代码

function display_site_stats() {
    // 获取统计数据
    $total_posts = wp_count_posts()->publish;
    $site_uptime = get_site_uptime();
    $last_update = get_last_update_time();
    $total_word_count = get_total_word_count();

    // 输出HTML
    $stats = [
        '文章数目' => ['value' => $total_posts, 'class' => 'purple'],
        '存活天数' => ['value' => $site_uptime, 'class' => 'violet'],
        '上次更新' => ['value' => $last_update, 'class' => 'red'],
        '文章字数' => ['value' => $total_word_count . ' 万', 'class' => 'red']
    ];

    $output = '<div style="background: #fff; padding: 10px; border-radius: 5px; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.1);">';
    foreach ($stats as $text => $data) {
        $output .= sprintf(
            '<div style="display: flex; align-items: center; margin-bottom: 10px;">
                <span style="flex: 1;">%s</span>
                <span style="background: %s; color: #fff; padding: 2px 8px; border-radius: 12px; font-size: 0.9em;">%s</span>
            </div>',
            esc_html($text),
            esc_attr(get_badge_color($data['class'])),
            esc_html($data['value'])
        );
    }
    $output .= '</div>';

    return $output; // 返回输出的HTML
}

function get_badge_color($class) {
    switch ($class) {
        case 'purple':
            return '#9c27b0';
        case 'violet':
            return '#7e57c2';
        case 'red':
            return '#e53935';
        default:
            return '#e0e0e0';
    }
}

function get_site_uptime() {
    $start_date = new DateTime('2023-04-05'); // 替换为你的网站创建日期
    $interval = $start_date->diff(new DateTime());
    return $interval->days . '天'; // 直接返回存活的天数
}

function get_last_update_time() {
    $last_post = wp_get_recent_posts(['numberposts' => 1])[0];
    $time_difference = time() - strtotime($last_post['post_date']);

    if ($time_difference < 60) return '刚刚';
    if ($time_difference < 3600) return floor($time_difference / 60) . '分钟前';
    if ($time_difference < 86400) return floor($time_difference / 3600) . '小时前';
    return floor($time_difference / 86400) . '天前';
}

function get_total_word_count() {
    $posts = get_posts(['numberposts' => -1]);
    $total_word_count = array_sum(array_map(function($post) {
        return str_word_count(strip_tags($post->post_content));
    }, $posts));
    return round($total_word_count / 10000, 2); // 返回万字数
}

// 注册短代码
add_shortcode('xrbk-cbls', 'display_site_stats');

然后在WordPress小工具中添加文本，里面输入[xrbk-cbls]
