Typecho无插件实现回复可见效果代码记录

<?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("/\[hide\](.*?)\[\/hide\]/sm",'<div class="reply2view">$1</div>',$this->content);
}
else{
$content = preg_replace("/\[hide\](.*?)\[\/hide\]/sm",'<div class="reply2view">此处内容需要评论回复后方可阅读。</div>',$this->content);
}
echo $content
?>
