我是laravel的初学者，我在编程方面很虚弱，但是我在尝试学习编程方面正处于尝试之中，并且正在尝试建立一个电子商务网站，因此我的问题与管理员部分的订单状态有关（管理员可以更新订单状态）我找不到为此的解决方案，所以我需要帮助
当我单击更新时，出现此错误：
ErrorException (E_NOTICE)
Undefined index: id
public function findOrderByNumber($orderNumber)
{
return Order::where('order_number', $orderNumber)->first();
}
/**
* @param array $params
* @return mixed
*/
public function updateOrder(array $params)
{
$order = $this->findOrderById($params['id']);
$collection = collect($params)->except('_token');
$order->update();
return $order;
}
我希望管理员可以在编辑订单状态页面中更改和更新订单状态，并在order：index.blade.php视图中更改订单状态 那我该怎么解决呢？非常感谢你
这是代码：
订单合同：
<?php
namespace App\Contracts;
interface OrderContract
{
public function storeOrderDetails($params);
public function listOrders(string $order = 'id', string $sort = 'desc', array $columns = ['*']);
/**
* @param int $id
* @return mixed
*/
public function findOrderById(int $id);
public function findOrderByNumber($orderNumber);
/**
* @param array $params
* @return mixed
*/
public function updateOrder(array $params);
/**
* @param $id
* @return bool
*/
public function deleteOrder($orderNumber);
}

*/
public function deleteOrder($orderNumber)
{
