我有一個重置密碼功能。我想知道成功重置密碼后如何將用戶重定向到登錄頁面。這是我的代碼。public function UpdatePassword(){    $tok = $_SESSION['token'];    $newpass = md5($this->security->xss_clean($this->input- >post('newpass')));    $confpass = md5($this->security->xss_clean($this->input- >post('confpass')));        if($newpass == $confpass){            $this->db->where('password', $tok);            $this->db->update('user', array('password' => $confpass));            if($this->db->affected_rows() > 0){            return true;            }else{            return false;            }           }        else{            $this->session->set_flashdata('error_submit',  'new and conf does not match');            redirect(base_url('Login/resetpassword'));        }        //redirect(base_url('Login/Login'));    }
