<!-- start 读者墙 Edited By iSayme--><?php $query="SELECT COUNT(comment_ID) AS cnt, comment_author, comment_author_url, comment_author_email FROM (SELECT * FROM $wpdb->comments LEFT OUTER JOIN $wpdb->posts ON ($wpdb->posts.ID=$wpdb->comments.comment_post_ID) WHERE comment_date > date_sub( NOW(), INTERVAL 24 MONTH ) AND user_id='0' AND comment_author_email != '这里改成你自己的邮箱' AND post_password='' AND comment_approved='1' AND comment_type='') AS tempcmt GROUP BY comment_author_email ORDER BY cnt DESC LIMIT 39";//大家把管理员的邮箱改成你的,最后的这个39是选取多少个头像，大家可以按照自己的主题进行修改,来适合主题宽度
$wall = $wpdb->get_results($query);
$maxNum = $wall[0]->cnt;
foreach ($wall as $comment)
{
$width = round(40 / ($maxNum / $comment->cnt),2);//此处是对应的血条的宽度
if( $comment->comment_author_url )
$url = $comment->comment_author_url;
else $url="#";
$avatar = get_avatar( $comment->comment_author_email, $size = '36', $default = get_bloginfo('wpurl').'/avatar/default.jpg' );
$tmp = "<li><a target=\"_blank\" href=\"".$comment->comment_author_url."\">".$avatar."<em>".$comment->comment_author."</em> <strong>+".$comment->cnt."</strong></br>".$comment->comment_author_url."</a></li>";
$output .= $tmp;
}
$output = "<ul class=\"readers-list\">".$output."</ul>";
echo $output ;
?><!-- end 读者墙 -->

3.在主题的style.css文件中添加下面的css样式（我修改过，你也可以根据你自己的主题修改相应的代码）

4.新建一个页面，模板选择readerwall.php，内容不填，标题填“读者墙”，然后把页面添加到菜单中即可。
搞定！
