<!-- 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）

.readers-list {
    line-height: 18px;
    text-align: left;
    overflow: hidden;
    _zoom: 1
}
 
.readers-list li {
    width: 200px;
    float: left;
    *margin-right: -1px
}
 
.readers-list a, .readers-list a:hover strong {
    
    background-image: -webkit-linear-gradient(#f8f8f8, #f2f2f2);
    background-image: -moz-linear-gradient(#f8f8f8, #f2f2f2);

    padding: 4px 4px 4px 44px;

}
 
.readers-list img, .readers-list em, .readers-list strong {

    -moz-transition: all .2s ease-out;
    transition: all .2s ease-out

    border-radius: 2px
}
 
.readers-list em {
    color: #666;
    font-style: normal;
    margin-right: 10px
}
 
.readers-list strong {
    color: #ddd;
    width: 40px;
    text-align: right;
    position: absolute;
    right: 6px;
    top: 4px;
    font: bold 14px/16px microsoft yahei
}
 
.readers-list a:hover {
    border-color: #bbb;
    box-shadow: #ccc 0 0 2px;
    background-color: #fff;
    background-image: none
}
 
.readers-list a:hover img {
    opacity: .6;
    margin-left: 0
}
 
.readers-list a:hover em {
    color: #EE8B17;
    font: bold 12px/36px microsoft yahei
}
 
.readers-list a:hover strong {
    color: #EE8B17;
    right: 150px;
    top: 0;
    text-align: center;
    border-right: #ccc 1px solid;
    height: 44px;
    line-height: 40px
}
 
.readers-list {
    line-height: 18px;
    text-align: left;
    _zoom: 1;
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
    -o-text-overflow: ellipsis;
}

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！
