Laravel - 將數組的值和鍵傳遞給數據庫

Question

我目前在結帳網站時遇到問題。 我需要將 arrays 的值和鍵傳遞給數據庫，但我不知道如何從數組中獲取它們。

$request->toArray()看起來像這樣：

用於將其傳遞給數據庫的代碼：

    foreach ($request->toArray() as $key => $value)
    {

        // dd($request->toArray());
        
        $ordered_ticket = new OrderedTickets();
        $ordered_ticket->checkout_id = $uuid;
        ordered_ticket->ticket_id =  // should be the key of the array
        $ordered_ticket->amount =  // should be the value of the array
        $ordered_ticket->price = 100;
        $ordered_ticket->save();
            
    }

像這樣遍歷嵌套數組

foreach ($request->toArray() as $key => $value)
{
    
    if($key === 'ticket'){
       foreach($value as $ticketId => $ticketValue)
            $ordered_ticket = new OrderedTickets();
            $ordered_ticket->checkout_id = $uuid;
            $ordered_ticket->ticket_id = $ticketId; // should be the key of the array
            $ordered_ticket->amount = $ticketValue; // should be the value of the array
            $ordered_ticket->price = 100;
            $ordered_ticket->save();
        }
 }
}

或者更簡單：

foreach ($request->toArray()['ticket'] as $key => $value)
{
    
            $ordered_ticket = new OrderedTickets();
            $ordered_ticket->checkout_id = $uuid;
            $ordered_ticket->ticket_id = $key; // should be the key of the array
            $ordered_ticket->amount = $value; // should be the value of the array
            $ordered_ticket->price = 100;
            $ordered_ticket->save();

}
