      $data[&#39;address&#39;] = $_POST[&#39;address&#39;];
      $result=$db->where(&#39;id=&#39;.$_POST[&#39;id&#39;])->save($data);   // 根据条件保存修改的数据
      if($result){

    $result=$db->where(&#39;id=&#39;.$_GET[&#39;id&#39;])->delete();   // 删除id为5的用户数据
    if($result){
      $this->redirect(&#39;Index/index&#39;,&#39;&#39;, 2,&#39;数据删除成功&#39;);    //页面重定向
