Laravel yajra表分页服务器端，点击第二页后无法点击第三页

Question

<p>基本上，这是第一页（可以看第一张图），总共有8条数据，每页会显示2条数据。 第一张图片</p> <p>所以当我点击第二页时，第三页就会丢失，无法点击。你可以看到第二张图片（这是第二页的第二张图片，但是正如你所看到的，没有按钮让我点击第三页）</p> <p>正如您在下面看到的，我尝试添加数据表并将 ->setOffset($start) 放入代码中。但它不起作用。请任何人帮助我。</p>

公共函数reservationListing(Request $request)

        }

        }
        $query->orderBy(“reservation_date”);
        $reservationList = $query->get();

        $start = ($request->start) ? $请求->开始：0；

        返回数据表::of($reservationList)
        ->setOffset($start)
        ->addIndexColumn()  
            -> make(真);
    }</pre></p>            

Answer 1

我已经得到了答案，我只是更改了一些代码并删除了一些代码：

if (!empty($req['start'])) {
        $query->skip($req['start']);


    }

    if (!empty($req['start'])) {
        $query->take($req['length']);
    }

这是该函数的完整代码：

public function reservationListing(Request $request)
{

    $req = $request->all();

    $query = EventReservation::selectRaw("reservation_date,event_reservations.outlet_id,event_reservations.event_id,SUM(event_reservations.total_adults) as ttl_adult,
    SUM(event_reservations.total_kids) as ttl_kid,SUM(event_reservations.total_adults + event_reservations.total_kids) as ttl_pax,
    SUM(CASE WHEN event_reservations.total_attendees is NULL then 0 Else event_reservations.total_attendees End) as ttl_attended,
    SUM(CASE WHEN payment_status = 'pending' THEN 1 ELSE 0 END) as ttl_pending,SUM(CASE WHEN payment_status = 'paid' THEN 1 ELSE 0 END) as ttl_paid,
    events.name as event_name,outlets.name as outlet_name")
        ->leftjoin("events", "events.id", "=", "event_reservations.event_id")
        ->leftjoin("outlets", "outlets.id", "=", "event_reservations.outlet_id")
        ->groupby('reservation_date')
        ->groupby('outlet_id')
        ->groupby('event_id');

    if (!empty($req['date_to']) && !empty($req['date_to'])) {
        $query->whereRaw("DATE(reservation_date) BETWEEN '".$req['date_from']."' AND '".$req['date_to']."'");
    }

    if (!empty($req['outlet_id'])) {
        $query->where("event_reservations.outlet_id", $req['outlet_id']);
    }

    if (!empty($req['event_id'])) {
        $query->where("event_reservations.event_id", $req['event_id']);
    }

    $query->orderBy("reservation_date");

    $reservationList = $query->get();

    return Datatables::of($reservationList)
    ->make(true);
}
