    {
      $this->display();
    }
    else
    {
      $db=D("Info");
       
      $shu=array(
        array("Code","require","代号不能为空",0,"regex",3),
      );
       
      if(!$db->validate($shu)->create())
      {
        echo $db->getError();
      }
      else
      {
        echo"验证通过";
      }
    }
  }

function ming()
  {
    $code=$_POST["code"];
    $db=D("Info");
    $data=$db->find($code);
    $name=$data["name"];
    $this->ajaxReturn($name,"eval");
  }
