在 functions.php 中写入代码:

function get_comment_at($coid){
    $db   = Typecho_Db::get();
    $prow = $db->fetchRow($db->select('parent,status')->from('table.comments')
        ->where('coid = ?', $coid));
    $mail = "";
    $parent = @$prow['parent'];
    if ($parent != "0") {
        $arow = $db->fetchRow($db->select('author,status,mail')->from('table.comments')
            ->where('coid = ?', $parent));
        @$author = @$arow['author'];
        $mail = @$arow['mail'];
        if(@$author && $arow['status'] == "approved"){if (@$prow['status'] == "waiting"){echo '<p class="commentReview">(评论正在审核中)</p>';}
        echo '<a href="#comment-' . $parent . '" class="comment-at">@' . $author . '</a>';
        }else{if (@$prow['status'] == "waiting"){echo '<p class="commentReview">(评论正在审核中)</p>';
        }else{echo '';}}} else {if (@$prow['status'] == "waiting"){echo '<p class="commentReview">(评论正在审核中)</p>';}else{echo '';}}
}

在 commentes.php 评论输出位置写入代码:

<?php $parentMail = get_comment_at($comments->coid)?><?php echo $parentMail;?><?php $comments->content(); ?>
