我想問一下，為啥我的就會報警告 foreach和section都會報 Notice: Undefined index: cancelOrder in H:\StudyProgram\wamp\www\SmartyTest\libs\ORG\Smarty\sysplugins\smarty_internal_templatebase.php(165) : eval()'d code on line 32

代碼：

controller

<?php

class orderController{

function show(){//控制器的作用是調用模型，并調用視圖，將模型產生的數據傳遞給視圖，并讓相關視圖去顯示。

global $view;

//$testModel = new testModel();

//$orderModel = M('order');

//$cancelArray = $orderModel->getCancelOrder();

//$testView = V('test');

//$testView -> display($data);

$cancelArray = array(

???????? array('objectId' =>1 ,

???????? ?'installmentNo' =>2 ),

???????? array('objectId' =>2 ,

???????? ?'installmentNo' =>1 )

);

print_r($cancelArray);

$view ->assign('cancelArray',$cancelArray);

$view ->display('order.tpl');

}

}

?>

tpl

<foreach item=cancelOrder from=$cancelArray >

? ? {$cancelOrder.objectId}

? ? {$cancelOrder.installmentNo}

? ?

? ?<br />

? ??

</foreach>
