如何将id从while循环传递给控制器​​[laravel]

Question

我是laravel的新手，所以我正在寻找如何将特定的id发送到控制器以便从另一个表中获取数据？

例如

while($shipment = sqlsrv_fetch_array($get_customer_rule,SQLSRV_FETCH_ASSOC)) {

    //display some data ......

    // inside the loop i will have another query to get data from another table has //relation with shipment table

    $id = $shipment['id'];
    $customer = "SELECT * FROM [ccctadm].[customer] WHERE id = '$id' ";

    $get_customer_info = sqlsrv_query($conn, $customer);
    $get_customer_id = sqlsrv_fetch_array($get_customer_info,SQLSRV_FETCH_ASSOC);

    $customer_id = $get_customer_id['customerid'];
}

我无法在laravel中的while循环中编写查询，因此如何将货件ID传递给控制器​​以便我可以获取与货件相关的客户数据

由于你是Laravel的新手，也许你应该首先学习Laravel方法。观看此视频，了解如何使用Eloquent以及该系列中的所有其他视频。 https://laracasts.com/series/laravel-from-scratch-2017/episodes/7

一旦了解了这一点，您就可以将查询重写为

$shipments = Shipement::all();
foreach( $shipments as $shipment ) {
    $customer = $shipment->customer;
    $customer_id = $customer->id;
}

当你进一步使用laravel并且能够使用急切加载时，你会做得更好

$shipments = Shipment::with('customer')->get();

在你看来

@foreach($shipments as $shipment)
    Customer ID is : {{ $shipment->customer->id }}
@endforeach

您决定与Laravel合作。利用它。它将使一切变得更容易，并加快您的开发过程。

如果您想坚持原始SQL查询，可以使用查询构建器

$result = DB::select("SELECT * FROM [ccctadm].[customer] WHERE id = ?", [$id]); 

使用结果
