$username=$this->input->post('username',TRUE);
                        $password=md5($this->input->post('password',TRUE));
                        $user=$this->user_model->login($username,$password);
                        if($user['password'] != $password) redirect('admin/login');//我这样写 这里报错

贴处理程序，不是html代码

楼主,你后台做了表单验证么???比如空值验证....

ahkxhyl

登录未做空值验证

你没有做空值验证当然会报错，因为你把空值插入到了sql语句查询。。。。会报sql语句错误的。
你要用ci的表单验证做个空值判断
