如何将相同的id插入到其他表？[重复]

Question

我有一个表，它类似于自动递增，我尝试这样做：在一个订单表中插入例如您的id、产品名称、价值和交货地址，我需要它在另一个名为订单id的表中，并将其插入订单详细信息中。使用这种方法

$order = new order;
        $order->id_user = 1; //$iduser;
        $order->name_destain = $request->name;
        $order->state = 1;
        $order->total = $request->total;
        $order->created_at = Carbon::now();;
        $order->updated_at = Carbon::now();;
        $order->save();

Answer 1

你可以这样做，我假设其他表的名称是order_details它的模型是OrderDetail.php

        $order = new order;
        $orderDetailObj = new OrderDetail; // or you can insert it in existing one OrderDetail::find($id); here $id is the particular (primary key)id of OrderDetail
        $order->id_user = 1; //$iduser;
        $order->name_destain = $request->name;
        $order->state = 1;
        $order->total = $request->total;
        $order->created_at = Carbon::now();;
        $order->updated_at = Carbon::now();;
        if($order->save()){
            $orderDetailObj->order_id = $order->id_user
            $orderDetailObj->update();
            return true;   
        }
