这段免插件读者墙代码原型，确实无此功能，之前改过，后来忘记加了，因为很少用IE看自己的WordPress博客，有人提议加上，就改了一下，愿意折腾的可以按下面方法修改：主题中添加的免插件读者墙代码在原型基础上稍作修改添加了external nofollow属性，原出处未知：

<?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=$wpdb->comments.comment_post_ID) WHERE comment_date > date_sub( NOW(), INTERVAL 1 MONTH ) AND user_id='0' AND comment_author_email != '' AND post_password='' AND comment_approved='1' AND comment_type='') AS tempcmt GROUP BY comment_author_email ORDER BY cnt DESC LIMIT 10";$wall = $wpdb->get_results($query);foreach ($wallas$comment){if( $comment->comment_author_url )$url = $comment->comment_author_url;else$url="#";$r="rel='external nofollow'";$tmp = "<a href='".$url."' '".$r."' title='".$comment->comment_author." (留下".$comment->cnt."个脚印)'>".get_avatar($comment->comment_author_email, 32)."</a>";$output .= $tmp;}echo$output ;?>

上面代码，未针对IE添加atl属性，参考了一下别人的修改方法，改为：

<?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=$wpdb->comments.comment_post_ID) WHERE comment_date > date_sub( NOW(), INTERVAL 1 MONTH ) AND user_id='0' AND comment_author_email != '' AND post_password='' AND comment_approved='1' AND comment_type='') AS tempcmt GROUP BY comment_author_email ORDER BY cnt DESC LIMIT 10";$wall = $wpdb->get_results($query);foreach ($wallas$comment){if( $comment->comment_author_url )$url = $comment->comment_author_url;else$url="#";$r="rel='external nofollow'";$imgsize="32";$tmp = "<a target='_blank' href='".$url."' title='".$comment->comment_author." (留下".$comment->cnt."个脚印)'><img width='".$imgsize ."' height='".$imgsize ."' src='https://www.gravatar.com/avatar.php?gravatar_id=".md5( strtolower($comment->comment_author_email) )."&size=".$imgsize ."&d=identicon&r=G' alt='".$comment->comment_author."(留下".$comment->cnt."个脚印)' /></a>";$output .= $tmp;}echo$output ;?>

具体针对热点新闻2.4版主题修改方法：

打开：top_comment.php及Message.php

找到：

$tmp = "<a href='".$url."' '".$r."' title='".$comment->comment_author." (留下".$comment->cnt."个脚印)'>".get_avatar($comment->comment_author_email, 32)."</a>";

替换为：

$imgsize="32";$tmp = "<a target='_blank' href='".$url."' title='".$comment->comment_author." (留下".$comment->cnt."个脚印)'><img width='".$imgsize ."' height='".$imgsize ."' src='https://www.gravatar.com/avatar.php?gravatar_id=".md5( strtolower($comment->comment_author_email) )."&size=".$imgsize ."&d=identicon&r=G' alt='".$comment->comment_author."(留下".$comment->cnt."个脚印)' /></a>";

改后可以看看效果
