试图存储多个数据（行），但它只在laravel中创建1行

I am trying to store array data(saving multiple row) but on single row is being store in my database.

here's my form,

{!! Form::open(['route' => 'warehouse1.store']) !!}
@foreach($order->orderItems as $orderItem)
    <input type="number" name="stock_in_qty[]" id="stock_in_qty_{{$orderItem->id}}" class="form-control stock_in_qty" min="1" value="{{$orderItem->quantity}}" data-max="{{$orderItem->quantity}}" onkeyup="check(this);"/>
    <script type="text/javascript">
        var $orderItem_id = {{$orderItem->id}};
            $('#stock_in_qty_'+$orderItem_id).on('mouseup keyup', function () {
            $(this).val(Math.min({{$orderItem->quantity}}, Math.max(1, $(this).val())));
        });
    </script>
    {{ Form::date('delivery_date[]',today(), ['class' => 'form-control date', 'style' => 'width:200px;','required']) }}
    {!! Form::text('delivery_note[]', null, ['class'=>'form-control']) !!}                  
    {!! Form::hidden('order_id[]', $order->id) !!}
    {!! Form::hidden('order_item_id[]', $orderItem->id ) !!}
    {!! Form::hidden('company_id[]', $order->company->id) !!}
    {!! Form::hidden('stock_out_qty[]',null) !!}
    {!! Form::hidden('transfer_to[]', null) !!}
    {!! Form::hidden('user_id[]',auth()->user()->id ) !!}
@endforeach

{!! Form::submit('Add to stocks', [ 'class'=>'btn btn-info']) !!} 
{!! Form::close() !!}

Here's my store function

public function store(Request $request)
{
    $input = $request->all();

    for($i=0; $i<= count($input['stock_in_qty']); $i++) {

        if(empty($input['stock_in_qty'][$i]) || !is_numeric($input['stock_in_qty'][$i])) continue;

        $acceptItem = [
            'order_id' => $input['order_id'][$i],
            'order_item_id' => $input['order_item_id'][$i],
            'delivery_date' => $input['delivery_date'][$i],
            'company_id' => $input['company_id'][$i],
            'stock_in_qty' => intval($input['stock_in_qty'][$i]),
            'stock_out_qty' => $input['stock_out_qty'][$i],
            'transfer_to' => $input['transfer_to'][$i],
            'delivery_note' => $input['delivery_note'][$i],
            'user_id' => $input['user_id'][$i]  
        ];


        Warehouse1stocks::create($acceptItem);
        return redirect()->route('orders.index');
    }
}

dd($acceptItem); result

dd($input) result

what do you think is the possible cause of this? Thank you in advance!

You need to change your controller method to this

public function store(Request $request)
{
    $input = $request->all();

    $items = [];

    for($i=0; $i < count($input['stock_in_qty']); $i++) {

        if(empty($input['stock_in_qty'][$i]) || !is_numeric($input['stock_in_qty'][$i])) continue;

        $acceptItem = [
            'order_id' => $input['order_id'][$i],
            'order_item_id' => $input['order_item_id'][$i],
            'delivery_date' => $input['delivery_date'][$i],
            'company_id' => $input['company_id'][$i],
            'stock_in_qty' => intval($input['stock_in_qty'][$i]),
            'stock_out_qty' => $input['stock_out_qty'][$i],
            'transfer_to' => $input['transfer_to'][$i],
            'delivery_note' => $input['delivery_note'][$i],
            'user_id' => $input['user_id'][$i]  
        ];


        array_push($items, Warehouse1stocks::create($acceptItem));
    }

    dd($items);

    return redirect()->route('orders.index');
}

Because as your code clearly shows below after the creation first acceptItem you will be redirected to the route('orders.index') and not create the other acceptItems

for($i=0; $i<= count($input['stock_in_qty']); $i++) {

    if(empty($input['stock_in_qty'][$i]) || !is_numeric($input['stock_in_qty'][$i])) continue;

    $acceptItem = [
        'order_id' => $input['order_id'][$i],
        'order_item_id' => $input['order_item_id'][$i],
        'delivery_date' => $input['delivery_date'][$i],
        'company_id' => $input['company_id'][$i],
        'stock_in_qty' => intval($input['stock_in_qty'][$i]),
        'stock_out_qty' => $input['stock_out_qty'][$i],
        'transfer_to' => $input['transfer_to'][$i],
        'delivery_note' => $input['delivery_note'][$i],
        'user_id' => $input['user_id'][$i]  
    ];


    Warehouse1stocks::create($acceptItem);
    return redirect()->route('orders.index');
}

So you need to move the return statement out of the for loop.
