前言

废话不多说，直入主题

PHP代码

在子比主题的主题目录下，header.php底部添加以下函数代码：

<!--调用信息代码-->
<!--底部统计用的代码-->
<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
 */
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
$wdyx_time = floor((time()-strtotime("2020-04-29"))/86400);
echo "var tj_wdyx="."'$wdyx_time'";
?>
</script>
<!--调用信息代码结束-->

二、HTML+JS代码

下面是HTML+js代码，至于放在哪，【外观】【小工具】【自定义HTML】【首页底部全宽度】，不想多说了。

<div id="yoy-info-wg-mian">
  <div class="yoy-info-item">
    <div class="yoy-yxsj-item">
      <svg class="icon fa-2x" aria-hidden="true">
        <use xlink:href="#iconxiuxiyixia"></use>
      </svg>
      <span class="yoy-i-num"
        ><script type="text/javascript">
          document.write(tj_wdyx);
        </script></span
      >
      <p>运行时间</p>
    </div>
    <div class="yoy-yhzs-item">
      <svg class="icon fa-2x" aria-hidden="true">
        <use xlink:href="#iconzhanghuguanli"></use>
      </svg>
      <span class="yoy-i-num"
        ><script type="text/javascript">
          document.write(tj_jstext);
        </script></span
      >
      <p>用户总数</p>
    </div>
    <div class="yoy-llzs-item">
      <svg class="icon fa-2x" aria-hidden="true">
        <use xlink:href="#iconyanjing"></use>
      </svg>
      <span class="yoy-i-num"
        ><script type="text/javascript">
          document.write(tj_view);
        </script></span
      >
      <p>浏览总数</p>
    </div>
    <div class="yoy-wz-item">
      <div class="yoy-wz-sty yoy-wzzs-item">
        <svg class="icon fa-2x" aria-hidden="true">
          <use xlink:href="#iconxiezuoye"></use>
        </svg>
        <span class="yoy-i-num"
          ><script type="text/javascript">
            document.write(tj_rzzs);
          </script></span
        >
        <p>文章总数</p>
      </div>
      <div class="yoy-wz-sty yoy-jrfb-item">
        <svg class="icon fa-2x" aria-hidden="true">
          <use xlink:href="#iconaixin"></use>
        </svg>
        <span class="yoy-i-num"
          ><script type="text/javascript">
            document.write(tj_24h);
          </script></span
        >
        <p>今日发布</p>
      </div>
    </div>
    <div class="yoy-sjcs-item">
      <div class="yoy-sjcj-m">
        <span style="font-size: 30px">今日</span>
        <div id="yoy-date-text"></div>
        <div id="yoy-week-text"></div>
        <div class="yoy-meo-item">
          <img id="yoy-meos" src="https://img.uuno.cc/upload/2022-04-13/2204131132369792.png" alt="emo" />
        </div>
        <div class="yoy-sjcj-content">
          <span id="yoy-fatalism"></span>
        </div>
      </div>
    </div>
  </div>
</div>
<script>
$(function () {
  var myDate = new Date();
  var year = myDate.getFullYear(); //获取当前年
  var mon = myDate.getMonth() + 1; //获取当前月
  var date = myDate.getDate(); //获取当前日
  var week = myDate.getDay();
  var weeks = [
    "星期日",
    "星期一",
    "星期二",
    "星期三",
    "星期四",
    "星期五",
    "星期六"
  ];
  $("#yoy-date-text").html(year + "年" + mon + "月" + date + "日");
  $("#yoy-week-text").html(weeks[week]);
  if (week > 0 && week < 5) {
    $("#yoy-fatalism").html("再坚持" + (5 - week) + "天就到周末啦！");
  } else if (week === 5) {
    $("#yoy-fatalism").html("啊啊啊，明天就是周末啦！");
  } else {
    $("#yoy-fatalism").html("今天是周末，好好休息一下吧！");
  }
  $("#yoy-meos").attr(
    "src","https://img.uuno.cc/img/bianhua/expression-" + week + ".png"
  );
});
$("#yoy-info-wg-mian").parents(".zib-widget").css({
  padding: "0",
  background: "none"
});
</script>

图标无法显示，是因为我用《阿里巴巴矢量库》，自己把下面的代码更改为其他icon的：

<svg class="icon fa-2x" aria-hidden="true">
          <use xlink:href="#iconaixin"></use>
        </svg>

【推荐】用http://www.fontawesome.com.cn/faicons/的话，用下面的代码应该就可以了，图标自己更改！！

<i class="fa fa-free-code-camp" aria-hidden="true"></i>

三、CSS代码

下面是CSS代码，原本一起放的，但是CSS Grid布局不兼容WP的自定义工具，所以就只能放在主题后台的【自定义CSS样式】里面

.yoy-info-item{display:grid;grid-gap:15px;grid-template-columns:repeat(5,1fr);grid-template-rows:repeat(2,1fr);width:100%;height:280px}
.yoy-llzs-item,.yoy-sjcs-item,.yoy-yhzs-item,.yoy-yxsj-item{width:100%;height:100%;border-radius:8px;text-align:center;box-shadow:0 2px 4px 0 rgba(0,0%,0%,5%);background-color:var(--main-bg-color);overflow:hidden;padding:5px;box-sizing:border-box}
.yoy-i-num{font-size:30px;font-weight:700}
.yoy-yxsj-item{display:flex;align-items:center;justify-content:center;flex-direction:column}
.yoy-yhzs-item{display:flex;align-items:center;justify-content:center;flex-direction:column}
.yoy-llzs-item{display:flex;align-items:center;justify-content:center;flex-direction:column}
.yoy-wz-item{display:grid;grid-gap:20px;grid-template-columns:repeat(2,1fr);grid-column:1/4;grid-row:1/2;overflow:unset!important;box-shadow:none!important;padding:0!important}
.yoy-wz-sty{width:100%;height:100%;border-radius:8px;display:flex;align-items:center;justify-content:center;flex-direction:column;background-color:var(--main-bg-color);box-shadow:0 2px 4px 0 rgba(0,0%,0%,5%)}
.yoy-sjcs-item{grid-row:1/3;grid-column:4/6}
.yoy-sjcj-m{position:relative;font-size:20px;font-weight:700;text-align:left;width:100%;height:100%;padding:10px;box-sizing:border-box}
.yoy-sjcj-content{text-align:center;margin-top:10px}
.yoy-meo-item{width:100px;height:100px;margin:0 auto}
.yoy-meo-item>img{width:100%;height:100%;background-size:cover;background-repeat:no-repeat;background-position:center center;cursor:pointer}
@media screen and (max-width:959px){.yoy-info-item{grid-gap:10px;grid-template-columns:repeat(3,1fr);grid-template-rows:repeat(4,1fr);height:500px}
.yoy-sjcs-item{grid-row:3/5;grid-column:1/4}
.yoy-i-num{font-size:20px}
.yoy-sjcj-m{font-size:16px}
}

其他WP主题使用，请注意：“background—Color:var(–main-bg-color);”这是子比主题的夜间背景切换，自己更换为“#fff”颜色，或者更换为你主题的背景颜色。
