Add order Laravel - laravel

Question

I am adding order to database. It works like this: When ordering is clicked, the order is created in the Order table, at the same time the product items are also added to the OrderItem table, via the order_id foreign key. But I don't know how to get the order_id, because it is added at the same time, and the Order id is increments.
public function save(array $data, int $id = null){
$idCurrent = Auth::id();
$orderItems = $data['orderItems'];
//add to Order
Order::updateOrCreate(
[
'id' => $id
],
[
'user_id' => $idCurrent,
'shipping_fee' => $data['shipping_fee'],
'total' => $data['total'],
'payment' => $data['payment'],
'status_id' => 1,
]
);
//add to OrderItem
foreach($orderItems as $item){
OrderItem::Create([
'order_id' => 222, //=> ?????????????
'product_id' => $item -> product_id,
'quantity' => $item->quantity,
]);
}
return true;
}

Answer 1

$order = Order::updateOrCreate(
[
'id' => $id
],
[
'user_id' => $idCurrent,
'shipping_fee' => $data['shipping_fee'],
'total' => $data['total'],
'payment' => $data['payment'],
'status_id' => 1,
]
);
//add to OrderItem
foreach($orderItems as $item){
OrderItem::Create([
'order_id' =>$order->id
'product_id' => $item -> product_id,
'quantity' => $item->quantity,
]);
}
return true;

Answer 2

Avoid multiple call to databases.
When you create order with
$order = Order::updateOrCreate(
[
'id' => $id
],
[
'user_id' => $idCurrent,
'shipping_fee' => $data['shipping_fee'],
'total' => $data['total'],
'payment' => $data['payment'],
'status_id' => 1,
]
);
next you should is to send just one request to database with
// create batch array
$insertOrderItems = [];
foreach($orderItems as $item){
$insertOrderItems[] = [
'product_id' => $item->product_id,
'quantity' => $item->quantity,
];
}
// insert all at once in batch mode making just one call to database
$order->orderItems()->create($insertOrderItems);
Presuming you have sorted relations in Order and OrderItem models.
