Laravel 5.7 中具有多个值的 Where 子句

Question

我正在尝试为公共汽车运输系统制作报告，报告的表格有“司机”和“路线”字段。当我选择“驱动程序”来获取报告或只选择“路线”来获取报告时，它工作正常，但是当我同时选择“驱动程序和路线”时出现问题。任何帮助将不胜感激

您需要将同时使用 driver_id 和 route_id 的部分修改为以下以实现您的目的（因为根据您的代码，当 route_id 或 driver_id 都在开始日期和结束日期之间时，您似乎想要结果, 但是您的代码会分别检查 driver_id 和 route_id 的 where 条件。您需要将它们包装在 where 中并在其中使用嵌套 where）：

if ($request->driverid and $request->routeid) {
    $data->where(function($q) use ($request)
    {
        $q->where('trips.driver_id', '=', $request->driverid)
        ->where('trips.route_id', '=', $request->routeid);
    });
}
