<?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 ?>

Typecho_Plugin::factory('Widget_Abstract_Contents')->excerptEx = array('moleft','one');
Typecho_Plugin::factory('Widget_Abstract_Contents')->contentEx = array('moleft','one');
class moleft {    public static function one($con,$obj,$text)
    {      $text = empty($text)?$con:$text;
      if(!$obj->is('single')){      $text = preg_replace("/\[hide\](.*?)\[\/hide\]/sm",' 此处内容已隐藏 ',$text);
      }
      return $text;
    }
}
