求大神支招。下面是代码：
public function login(){
$user = M('user');
$map = array();
$map['username']=$_POST['username'];
$map['pass']=md5($_POST['pass']);
$res=$user->where($map)->select();
if($res==null){
$this->error("用户名密码错误");
}else{
session("username",$_POST['username']);
$this->success("登录成功");
}
} 这里的username和pass都没错，数据库配置也没问题。
<form class="form-horizontal templatemo-login-form-2" role="form" action="__URL__/login" method="post">
