//wordpress读者墙-wazhuti.com
function readers_wall( $outer=‘.’,$timer=’30’,$limit=’18’ ){
global $wpdb;
$counts = $wpdb->get_results(“select count(comment_author) 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 $timer month ) and user_id=’0′ and comment_author != ‘”.$outer.“‘ and post_password=” and comment_approved=’1’ and comment_type=”) as tempcmt group by comment_author order by cnt desc limit $limit”);
foreach ($counts as $count) {
$avatar_url = get_bloginfo(‘wpurl’) . ‘/wp-content/avatar/’ . md5(strtolower($count->comment_author_email));
$c_url = $count->comment_author_url;
if ($c_url == ”) $c_url = ”;
$page .= ‘<li><a target=”_blank” rel=”external nofollow” alt=”‘ . $count->comment_author . ‘” href=”‘. $c_url . ‘”><span class=”pic”><img src=”‘ . $avatar_url . ‘.jpg” /></span><span class=”num”><strong>’. $count->cnt . ‘+</strong></span><span class=”name”>’ . $count->comment_author . ‘</span></a></li>’;
}
echo $page;
};

注$limit=’18’ ，即显示为18个读者。请在/wp-content/目录下新建avatar文件夹，用来存放头像缓存文件。
第二步：添加读者墙相应CSS样式
