如何实现WordPress读者墙按评论等级显示相应读者？

我们国内很多 WordPress 主题都会带有一个读者墙功能，Nana 主题也不一例外，但是看多了按总评论数的排行榜，是否有点腻歪？而且我们大多数主题都有评论等级的功能，是否想过读者按评论等级逐级显示出来？今天就教大家如何实现 WordPress 读者墙按评论等级显示相应读者。大概的效果图如下：

1、制作评论榜单模板。以 Nana 主题为例，找到 template-readers 文件，复制一份并重名为 template-pinglunbang，然后打开该文件，找到以下代码

Template Name: 读者百强榜

修改为

Template Name: 评论榜单

继续找到以下代码

<?php
function readers_wall($limit = "100")
{
global $wpdb;
$counts = $wpdb->get_results("SELECT count(comment_author) AS cnt, comment_author, comment_author_url, comment_author_email FROM $wpdb->comments WHERE user_id!='1' AND comment_author!='1' AND comment_approved='1' AND comment_type='' GROUP BY comment_author ORDER BY cnt DESC LIMIT $limit");
$i = 0;
$type='';
foreach ($counts as $count ) {
$i++;
$c_url = $count->comment_author_url;
if (!$c_url) {
$c_url = "https://boke112.com";
}
$tt = $i;
if ($i == 1) {
$tt = "读者之青龙";
}
else if ($i == 2) {
$tt = "读者之白虎";
}
else if ($i == 3) {
$tt = "读者之朱雀";
}
else if ($i == 4) {
$tt = "读者之玄武";
}
else {
$tt = "第" . $i . "名";
}
$avatar = my_avatar( $count->comment_author_email,36,$default='',$count->comment_author);
if ($i < 5) {
$type .= "<a class=\"item-top item-" . $i . "\" target=\"_blank\" href=\"" . $c_url . "\" title=\"【" . $tt . "】评论：" . $count->cnt . "\"><h4>【" . $tt . "】</h4>".$avatar."<strong>" . $count->comment_author . "</strong>" . $c_url . "</a>";
}
else {
$type .= "<a target=\"_blank\" href=\"" . $c_url . "\" title=\"【" . $tt . "】评论：" . $count->cnt . "\">" . $avatar . $count->comment_author . "</a>";
}
}
echo $type;
}
?>
<div class="readers">
<?php readers_wall(100);?>
</div>

修改为

<?php
function readers_wall($limit = 100)
{
global $wpdb;
$counts = $wpdb->get_results("SELECT count(comment_author_email) AS cnt, comment_author, comment_author_url, comment_author_email FROM $wpdb->comments WHERE user_id!='1' AND comment_approved='1' AND comment_type='' AND comment_author_url!='' GROUP BY comment_author_email ORDER BY cnt DESC LIMIT 0 , $limit");

保存并更新文件（以上代码中的评论的等级名称及相对应的评论数量请自行修改即可）。

2、新建评论榜单页面。后台新建一个页面，模板就选我们刚才新创建的“评论榜单”然后直接修好好固定链接之后直接发布即可。
