html用think.session.显示,怎么在控制器里面设置变量啊?TP框架我是初学者

<?phpnamespace home\controller;use think\controller;class logincontroller extends controller{    public function index()    {        $this->display('index/login');    }    public function logincl()    {         if (is_post) {                                $user = m('member')->where(array('mb_username' => admin))->find();   //在html里我用{$think.session.adminuser}，代码可以显示我当前登录的账号,但是我用下面{$think.session.test}，就显示不了,空白的,                $test = m('aconfig')->where(array('zcinfo' ))->find();      //我的html用{$think.session.test}代码这个显示不了,test变量的值,那里出错了吗,(aconfig 这个是数据库表名)                   session('test',$test['zcinfo']);             //我的html用{$think.session.test}代码这个显示不了,test变量的值,那里出错了吗,  (aconfig 这个是数据库表的字段名,我就是想在html显示这个字段里面值),求救                    session('adminuser', $user['mb_username']);                                                               $_session['logintime'] = time();                    die("<script>document.location.href='/admin.php/home/index/main';</script>");        }    }        }

            <td bordercolor="cccccc"><select name="opwww" id="opwww">            <option value="0" ';if ($Think.session.adminoff==0){echo "selected=selected";};echo '>开启注册系统</option>            <option value="1" ';if ($Think.session.adminoff==1){echo "selected=selected";};echo '>关闭注册系统</option>          </select>
