  </div>
  <div class="foot">
    <form method="post">
      <div class="panel" >
        <div class="panel-body" >
          <div class="form-group">
            <div class="field field-icon-right">
              <input id="nickname" type="text" class="input" name="nickname" placeholder="游客姓名"/>
            </div>
          </div>
          <div class="form-group">
            <div class="field field-icon-right">
              <input type="text" id="content" class="input" name="content" placeholder="留言内容"/>
            </div>
          </div>
          <div class="form-group">
            <span></span>
            <span class="field">
              <input type="text" id="email" class="input" name="email" placeholder="Email"/>

</div>
<script>
function clearDefaultText(){

  $data['email']=$_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();
