1.在子比主题的主题目录下，header.php底部添加以下函数代码：

<!--统计信息函数-->
<script type="text/javascript" >
<?php
//用户总数
$users = $wpdb->get_var("SELECT COUNT(ID) FROM $wpdb->users");echo "var tj_jstext="."'$users'";
?>
</script>
<script type="text/javascript" >
<?php
/*
 * WordPress获取今日发布文章数量
 *zje.cc
 */
function nd_get_24h_post_count(){
  $today = getdate();
  $query = new WP_Query( 'year=' . $today["year"] . '&monthnum=' . $today["mon"] . '&day=' . $today["mday"]);
  $postsNumber = $query->found_posts;
  return $postsNumber;
}
$post_24h = nd_get_24h_post_count();
echo "var tj_24h="."'$post_24h'";
?>
</script>
<script type="text/javascript" >
<?php
/*
 * WordPress整站文章访问计数
 *
 */
function nd_get_all_view(){
  global $wpdb;
  $count=0;
  $views= $wpdb->get_results("SELECT * FROM $wpdb->postmeta WHERE meta_key='views'");
  foreach($views as $key=>$value){
    $meta_value=$value->meta_value;
    if($meta_value!=' '){
      $count+=(int)$meta_value;
    }
  }return $count;
}
$post_view = nd_get_all_view();
echo "var tj_view="."'$post_view'";
?>
</script>
<script type="text/javascript" >
<?php
//日志总数
$count_posts = wp_count_posts(); 
$published_posts =$count_posts->publish;
echo "var tj_rzzs="."'$published_posts'";
?>
</script>
<script type="text/javascript" >
<?php
//稳定运行
$wdyx_time = floor((time()-strtotime("2023-06-01"))/86400);
echo "var tj_wdyx="."'$wdyx_time'";
?>
</script>

注：函数运行日期2020-3-28改为你自己网站运行的日期。

2.在子比主题，页面&显示 - 底部页脚 - 版块一设置- 版块内部 中填入如下代码

<!-- 信息统计开始 -->
<div id="nuandao">
  <div class="siteCount">
    <div class="wrapper">
      <ul>
        <li>
          <b>用户总数</b>
          <span>
            <script type="text/javascript">
              document.write(tj_jstext);
            </script>
          </span>
        </li>
        <li>
          <b>文章总数</b>
          <span>
            <script type="text/javascript">
              document.write(tj_rzzs);
            </script>
          </span>
        </li>
        <li>
          <b>浏览总数</b>
          <span>
            <script type="text/javascript">
              document.write(tj_view);
            </script>
          </span>
        </li>
        <li>
          <b>今日发布</b>
          <span></span>
          <span>
            <script type="text/javascript">
              document.write(tj_24h);
            </script>
          </span>
        </li>
        <li>
          <b>稳定运行</b>
          <span>
            <script type="text/javascript">
              document.write(tj_wdyx);
            </script>
          </span>
        </li>
      </ul>

    </div>
  </div>
</div>
<style type="text/css">
  /* 添加以下 CSS 样式 */
  #nuandao .siteCount ul li span {
    color: #FF69B4;
  }
</style>
<!-- 信息统计结束 -->

3.效果如下

4.如仅在首先显示，不占空间，可加入侧边栏（外观 - 小工具-自定义HTML 添加到首页 侧边栏）代码同上，效果如下
