Typecho无插件实现回复可见效果代码

<?php $this->content(); ?>

<?php
$db = Typecho_Db::get();
$sql = $db->select()->from('table.comments')
    ->where('cid = ?',$this->cid)
    ->where('mail = ?', $this->remember('mail',true))
    ->limit(1);
$result = $db->fetchAll($sql);
if($this->user->hasLogin() || $result) {
    $content = preg_replace("/\[reply\](.*?)\[\/reply\]/sm",'<div class="reply2view"><i class="icon-lock-open"></i>$1</div>',$this->content);
}
else{
    $content = preg_replace("/\[reply\](.*?)\[\/reply\]/sm",'<div class="reply2view"><i class="icon-lock"></i><strong><span style="color: #800000;">温馨提示</span></strong>：此处为隐藏内容，评论回复后方可阅读。</div>',$this->content);
}
echo $content
?>
