我的系统会生成一张如图所示的收据：

我的系统中还有一个制造商列表现在我想像这样修改这张收据，使产品应位于其制造商标题下，该标题还显示该制造商在该订单中销售的产品总量

我的收据代码在这里

 <table>

                            </tr>
                        </tfoot>
                    </table>

是否有我必须在这里应用的任何条件或我必须在模型或控制器文件中创建的任何功能。

【解决方案1】：

有解决办法首先我必须编辑 orderController.php 的变量，它正在发送这样的数据：

public function getInvoice($order){
    $order = Order::with('orderItems.product', 'salesmanRelation', 'orderBooker', 'clientRelation')->where('id', $order)->first();
    // dd($order);
    $orderItemsByVendor = [];
    foreach ($order->orderItems as $item) {
        if(isset($orderItemsByVendor[$item->product->company_name])) {
            array_push($orderItemsByVendor[$item->product->company_name]['items'], $item);
        } else {
            $total = 0;
            $company = $item->product->company_name;
            foreach($order->orderItems as $orderItem) {
                if($orderItem->product->company_name == $company) {
                    $total += $orderItem->quantity * $orderItem->product->selling_price;
                }
            }

            $orderItemsByVendor[$item->product->company_name] = ['items' => [$item], 'total' => $total];
        }
    }

    // dd($orderItemsByVendor);
    $data = ['order' => $order, 'items' => $orderItemsByVendor];
    return view('dashboard.invoice', compact('data'));
}

然后我必须像这样编辑 invoice.blade.php 文件：

                            <tbody>
                        @foreach($data['items'] as $vendor => $item) 
                            @foreach($item['items'] as $orderItem)
                                <tr>
                                    <td class="item-list">{{$orderItem->quantity}}</td>
                                    <td class="item-list">{{$orderItem->bonus_items}}</td>
                                    <td class="item-list">{{$orderItem->quantity + $orderItem->bonus_items}}</td>
                                    <td class="item-list">{{strtoupper($orderItem->product->product_name)}}</td>
                                    <td class="item-list">{{$orderItem->product->batch_no}}</td>
                                    <td class="item-list" colspan="2">{{$orderItem->product->selling_price}}</td>
                                    <td class="item-list"></td>
                                    <td class="item-list">{{$orderItem->product->selling_price *$orderItem->quantity}}</td>
                                </tr>
                            @endforeach
                            <tr>
                                <td class="vendor-heading" colspan="8">{{$vendor}}</td>
                                <td class="vendor-heading">{{$item['total']}}</td>
                            </tr>
                        @endforeach
                        </tbody>

and here is the required receipt fully working
