WordPress侧边栏信息统计美化版

教程:

1.PHP部分

创建PHP文件：widget-websitestat.php然后加入以下代码:

<?php // WordPress统计信息小工具 // 名称: 网站信息统计 // 定义小工具的类 EfanWebsitestat class EfanWebsitestat extends WP_Widget{ function __construct(){ // 定义小工具的构造函数 $widget_ops = array('classname' => 'widget_Websitestat', 'description' => '显示网站的统计信息'); // $this->WP_Widget(false, 'IXIAOJUN网站统计', $widget_ops); parent::__construct( false, '小君- 网站统计', $widget_ops); } function form($instance){ // 表单函数,控制后台显示 // $instance 为之前保存过的数据 // 如果之前没有数据的话,设置默认量 $instance = wp_parse_args( (array)$instance, array( 'title' => '网站信息统计', 'establish_time' => '2021-01-01' ) ); $title = htmlspecialchars($instance['title']); $establish_time = htmlspecialchars($instance['establish_time']); // 表格布局输出表单 $output = '<table>'; $output .= '<tr><td>标题</td><td>'; $output .= '<input id="'.$this->get_field_id('title') .'" name="'.$this->get_field_name('title').'" type="text" value="'.$instance['title'].'" />'; $output .= '</td></tr><tr><td>建站时间：</td><td>'; $output .= '<input id="'.$this->get_field_id('establish_time') .'" name="'.$this->get_field_name('establish_time').'" type="text" value="'.$instance['establish_time'].'" />'; $output .= '</td></tr></table>'; echo $output; } function update($new_instance, $old_instance){ // 更新数据的函数 $instance = $old_instance; // 数据处理 $instance['title'] = strip_tags(stripslashes($new_instance['title'])); $instance['establish_time'] = strip_tags(stripslashes($new_instance['establish_time'])); return $instance; }   function widget($args, $instance){ extract($args); //展开数组 $title = apply_filters('widget_title',empty($instance['title']) ? '&nbsp;' : $instance['title']); $establish_time = empty($instance['establish_time']) ? '2021-01-01' : $instance['establish_time']; echo $before_widget; echo $before_title . $title . $after_title; echo '<div class="widgest-boys"><ul>'; $this->efan_get_websitestat($establish_time); echo '</ul></div>'; echo $after_widget; }   function efan_get_websitestat($establish_time){ // 相关数的获取 global $wpdb; $count_posts = wp_count_posts(); $published_posts = $count_posts->publish; $comments_count = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments"); $time = floor((time()-strtotime($establish_time))/86400); $count_tags = wp_count_terms('post_tag'); $count_pages = wp_count_posts('page'); $link = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->links WHERE link_visible = 'Y'"); $users = $wpdb->get_var("SELECT COUNT(ID) FROM $wpdb->users"); $last = $wpdb->get_results("SELECT MAX(post_modified) AS MAX_m FROM $wpdb->posts WHERE (post_type = 'post' OR post_type = 'page') AND (post_status = 'publish' OR post_status = 'private')"); $last = date('Y-m-d', strtotime($last[0]->MAX_m)); $total_views = $wpdb->get_var("SELECT SUM(meta_value+0) FROM $wpdb->postmeta WHERE meta_key = 'views'"); // 显示数据 $output = '<div class="widgest-bg widgest-bg1"><div class="widgest-main"><div class="widgest-meat"><li>文章总数：'; $output .= $published_posts; $output .= ' 篇</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg2"><div class="widgest-main"><div class="widgest-meat"><li>评论数目：'; $output .= $comments_count; $output .= ' 条</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg3"><div class="widgest-main"><div class="widgest-meat"><li>标签总数：'; $output .= $count_tags; $output .= ' 个</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg4"><div class="widgest-main"><div class="widgest-meat"><li>浏览次数：'; $output .= $total_views; $output .= ' 次</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg5"><div class="widgest-main"><div class="widgest-meat"><li>友链总数：'; $output .= $link; $output .= ' 个</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg6"><div class="widgest-main"><div class="widgest-meat"><li>用户总数：'; $output .= $users; $output .= ' 个</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg7"><div class="widgest-main"><div class="widgest-meat"><li>运行天数：'; $output .= $time; $output .= ' 天</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg8"><div class="widgest-main"><div class="widgest-meat"><li>建站时间：'; $output .= $establish_time; $output .= '</li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg9"><div class="widgest-main"><div class="widgest-meat"><li>最后更新：'; $output .= $last; $output .= '</li></div></div></div>'; // 页面生成耗时+数据库查询 $output .= '<div class="widgest-bg widgest-bg10"><div class="widgest-main"><div class="widgest-meat"><li>数据查询：'; $output .= get_num_queries(); $output .= ' 次 </li></div></div></div>'; $output .= '<div class="widgest-bg widgest-bg11"><div class="widgest-main"><div class="widgest-meat"><li>生成耗时：'; $output .= timer_stop(0,5); $output .= '秒</li></div></div></div>'; echo $output; } } function EfanWebsitestat(){ // 注册小工具 register_widget('EfanWebsitestat'); } add_action('widgets_init','EfanWebsitestat'); ?>

在主题目录下functions.php文件，添加下面的函数代码:

//添加站点统计小工具  include("widget-websitestat.php");

2.CSS部分

在【外观】-【自定义】-【额外CSS】里添加CSS代码，代码在附件里面。你可以加入直接引入该文件到网站页脚:

<link rel="stylesheet" href="https://.../widget.css">

3.使用侧边栏工具

网站后台—外观—小工具— 网站统计，添加到侧边栏即可完成。
