php - Laravel 从集合中获取 Id

Question

Laravel 从集合中获取 Id

$collection = Test::whereDate('created_at', '=', $today)->where('cuid', $user->id)->where('month', date('m'))->get();        
        echo "<pre>";
        print_r($collection);
        echo "</pre>";
        exit();

如何从该集合返回 id

因为我想更新该特定 ID

Answer 1

如果user_id是唯一，则使用first()而不是get()

$collection = Test::whereDate('created_at', '=', $today)->where('cuid', $user->id)->where('month', date('m'))->first();

然后像这样访问id

$id = $collection->id;

否则，您需要循环集合数组并从单个对象访问id。
