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 ($wall as $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 ($wall as $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 ;
- ?>
具体针对本主题修改方法：
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>";
