PHP代码

public function hierarchicalauthority(){ if(isset($_POST['liuyan'])) {  $data['nickname']=$_POST['nickname'];  $data['content']=$_POST['content'];  $data['email']=$_POST['email'];  $data['status']=1;  $data['replytime']=date('Y-m-d H:i:s',time());  // print_r($data);die();  $user=M('daili_liuyan_guestbook');  $maxid=$user->max('id');  $data['id']=$maxid+1;  $user->add($data); // print_r($_POST);die(); } $guestbook = D('daili_liuyan_guestbook')->select(); $this->assign('guestbook',$guestbook); $this->display();}
