在 Laravel 9 中报错：Indirect modification of overloaded property ReturnOrder::$order has no effect
1、在 Laravel 9 中报错：Indirect modification of overloaded property ReturnOrder::$order has no effect。如图1
图1
1 2 3 4 5 6 7 8 9 10 | { "status_code": 500, "code": 0, "message": "Indirect modification of overloaded property ReturnOrder::$order has no effect", "trace": { "line": 648, "file": "E:\\object\\ReturnOrderService.php", "class": "ErrorException" }} |
2、代码实现如下
1 2 | $item->order = $keyedOrders[$item->order_id] ?? null;$item->order->returnOrders = $keyedOrderReturnOrders[$item->order_id] ?? new EloquentCollection(); |
2、调整后的代码实现如下，不再报错
1 2 3 4 | $item->order = $keyedOrders[$item->order_id] ?? null;if ($item->order) { $item->order->returnOrders = $keyedOrderReturnOrders[$item->order_id] ?? new EloquentCollection();} |
