我们如何查看预订日期是多季节的季节时间？

Question

我在laravel项目预订房间。我有一个日历来选择日期。我需要查看夏季或冬季的预订日期。如果不是在季节，请显示消息“抱歉不是季节时间”

我试过一些代码。如果表中只有一个条目，则此代码将起作用。请查看下面给出的详细信息并帮助我。谢谢。

季节（表）

id  summer  summer_open  summer_close winter winter_open winter_close hotel

   else {
       print_r($generateBookingDat. ' Sorry not a season time ');

Answer 1

由于您有多个季节，取决于年份，您必须在预订日期有效时打破循环：

foreach ($generateBookingDates as $key => $generateBookingDate) {
    $generateBookingDat = $generateBookingDate->format('Y-m-d'); //2019-09-17, 2019-09-18, 2019-09-19, 2019-09-20, 2019-09-21 

    $bookingDateSeason     = null;
    $bookingDateSeasonType = null;

    /* Checking season begin */
    foreach($seasons as $season) {
        if(($generateBookingDat >= ($season->summer_open)->format('Y-m-d')) && ($generateBookingDat < ($season->summer_close)->format('Y-m-d')))
        {
            $bookingDateSeasonType = 'summer';
            $bookingDateSeason     = $season;
            /* Stop the loop here at the first valid season */
            break;
        } 
        elseif(($generateBookingDat >= ($season->winter_open)->format('Y-m-d')) && ($generateBookingDat < ($season->winter_close)->format('Y-m-d'))) 
        {
            $bookingDateSeasonType = 'winter';
            $bookingDateSeason     = $season;
            /* Stop the loop here at the first valid season */
            break;
        }
    }

    if ($bookingDateSeason && $bookingDateSeasonType) 
    {
        print_r($generateBookingDat . ' booked on ' . $bookingDateSeasonType . ' season ' . $bookingDateSeason->{$bookingDateSeasonType});
    } 
    else 
    {
        print_r($generateBookingDat . ' Sorry not a season time ');

    }
}

// 2019-09-17 booked on summer season 2019
// 2019-09-18 booked on summer season 2019
// 2019-09-19 booked on summer season 2019
// 2019-09-20 Sorry not a season time
// 2019-09-21 Sorry not a season time

这个代码应该可以解决问题，但在我看来，你应该首先根据预订日期的年份来重温这个季节。通过这种方式，您可以避免在多个季节循环。

/* generating dates b/w two dates */
$generateBookingDates = $this->generateDates($dateBegin, $dateEnd); 

/* selecting seasons */
//$seasons              = Season::where('hotel', $request->hotelId)->get(); <--- Don't need this line anymore

foreach ($generateBookingDates as $key => $generateBookingDate) {
    $generateBookingDat = $generateBookingDate->format('Y-m-d'); //2019-09-17, 2019-09-18, 2019-09-19, 2019-09-20, 2019-09-21 

    $bookingYear = $generateBookingDate->format('Y');
    $season      = /* Season::where('hotel', $request->hotelId)->get(); ... and where year = $bookingYear */

    if(($generateBookingDat >= ($season->summer_open)->format('Y-m-d')) && ($generateBookingDat < ($season->summer_close)->format('Y-m-d')))
    {
        print_r($generateBookingDat. ' booked on summer season ');
    } 
    elseif(($generateBookingDat >= ($season->winter_open)->format('Y-m-d')) && ($generateBookingDat < ($season->winter_close)->format('Y-m-d'))) 
    {
        print_r($generateBookingDat. ' booked on winter season ');
    }
    else 
    {
        print_r($generateBookingDat. ' Sorry not a season time ');
    }
}

// 2019-09-17 booked on summer season
// 2019-09-18 booked on summer season
// 2019-09-19 booked on summer season
// 2019-09-20 Sorry not a season time
// 2019-09-21 Sorry not a season time

我的建议是你需要改进表结构然后你将处理这些类型的情况。你的表看起来像这样： -

 id  season_type open_date  close_date    hotel  year
 1    winter    2018-05-01   2018-09-20     1     2018
 2    summer    2019-05-01   2019-09-20     1     2019
 3    summer    2018-05-01   2018-09-20     2     2018
 4    summer    2019-05-01   2019-09-20     2     2019
 if you want to save year you can save  

完成相同的功能后，您可以： -

 $seasons = Season::where('hotel',1)->get();
 Example 1:-
 $dateBegin  = 2019-09-17; 
 $dateEnd    = 2019-09-22;
 Example 2:-
 $dateBegin  = 2019-09-17;
 $dateEnd    = 2019-09-19;

foreach($seasons as $key=> $season){
    if($season->open_date >=  $dateBegin && $season->close_date <= $dateEnd){
        print_r('booked on .'$season->season_type'. season '); //save this in one array variable
    }else{
         print_r(Sorry not a season time');
    }
}

如果您真的使用表结构，将来会遇到很多问题。希望能帮助到你
