WordPress侧边栏信息统计小工具(wp美化)

添加教程

1.在主题目录下创建widget-websitestat.php文件,然后把下面的php代码添加进去。

<?php
// WordPress统计信息小工具
// 名称: WIIUII 网站信息统计
// 修改版-美化版V1.0
// 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');
    parent::__construct(false, 'WIIUII 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']) ? ' ' : $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){
    // 相关数据的获取
    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:';
    $ou

2、在主题目录下functions.php文件,添加下面的函数代码即可。

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

3、在网站后台—》主题设置—》自定义代码—》自定义CSS样式,添加下面的CSS代码,主题没有自定义CSS样式的,在主题目录下style.css添加即可。
