Question

我搜索了所有谷歌，但无法找到我的问题的解决方案。所以我有这个系统，人们可以在特定的时间设置任务。

当时间已经完成任务时，我应该抛出错误让这个人知道时间已经保留，并且不会写入数据库。但由于某种原因，我无法做到这一点。

我认为问题与if语句

有关

这就是我尝试过的：http://pastebin.com/iA3RF6Mw

非常感谢：）

Answer 1

[固定]

我用一堆if else语句创建了一个新类。

public function checkBooking($booking,$em){

    $reservations = $em->getRepository("AppBundle:Applicant")->findBy(array("date" => $booking->getDate(),"room" => $booking->getRoom()));
    $errors = 0;
    $bookingTimeStart = $booking->getTimeStart()->format('H:i');
    $bookingTimeEnd = $booking->getTimeEnd()->format('H:i');
    foreach($reservations as $reservation){
        $timeStart = $reservation->getTimeStart()->format('H:i');
        $timeEnd = $reservation->getTimeEnd()->format('H:i');

        if($bookingTimeStart >= $timeStart && $bookingTimeStart <= $timeEnd){
            $errors++;
        }
        if($bookingTimeEnd >= $timeStart && $bookingTimeEnd <= $timeEnd){
            $errors++;
        }
        if($bookingTimeStart <= $timeStart && $bookingTimeEnd >= $timeEnd){
            $errors++;
        }

    }
    $error = array();
    if($errors > 0){
        $error[] = "THis room is already occupied.";
    }
    if($bookingTimeEnd < $bookingTimeStart){
        $error[] = "The end time cant be bigger than the begin time.";
    }

    if(count($error) == 0){
        $em->persist($booking);
        $em->flush();
        return array();
    }else{
        return $error;
    }

}

很难理解整个逻辑，但你做的事情肯定是错误的：

 $time_start = $em->getRepository("AppBundle:book")->findByName($form->get("timeStart") -> getViewData());

您按日期查询“名称”

关于如何在日期范围内检查实体，您应该创建自己的存储库方法，如

public function findInRange($timeStart, $timeEnd)
{
   $qb->select('b')
   ->from('Book','b')
   ->add('where', $qb->expr()->between(
            'b.date',
            ':from',
            ':to'
        )
    )
   ->setParameters(array('from' => $startDate, 'to' => $endDate));
  $query = $qb->getQuery();
  return $query->getResult();
}

比较时间与symfony2
