Question

我在for循环中输入了一个增量：

<input type="number" name="device_id_1">
<input type="number" name="device_id_2">
...
<input type="number" name="name_1">
<input type="number" name="name_2">

我使用ajax将数据传递给控制器：

dd( $request->all());
//dd will return the data like:

"device_id_1" => "100"
"name_1" => "Some Name"
"device_id_2" => "200"
"name_2" => "Other type"
....

我在保存每个 device_id_X 以及其余的问题时遇到了问题，我该如何在 foreach 循环中保存数据？

我当前的foreach循环当然不起作用：

       foreach ($devices as $index => $deviceId) {
            $devicesS[] = Device::create([
                'device_id' => $deviceId,
                'name' => $request->name_[$index],
                .....
            ]);
        }

您可能会：

<input type="hidden" name="items[]">
<input type="number" name="device_id_1">
<input type="number" name="name_1">
...
<input type="hidden" name="items[]">
<input type="number" name="device_id_2">
<input type="number" name="name_2">

这将导致以下结果：

foreach ($request->items as $index => $item) {
    $devices[] = [
        'device_id' => $request->get('device_id_'. $index + 1),
        'name' => $request->get('name_'. $index + 1)
    ];
}

Device::insert($devices);

保存多个输入增量
