Bitrix API

If you need to change the reservation settings, while you cannot edit the configuration (@see \Bitrix\Main\Configuration\Option), you can use this event to change the settings.

For example (realization event handler):

public static function OnReservationSettingsBuild(\Bitrix\Sale\Reservation\Configuration\ReservationSettingsBuildEvent $event)
{
if (self::isEnabledCrmReservation())
{
$event->getSettings()->setReserveCondition(
\Bitrix\Sale\Reservation\Configuration\ReserveCondition::ON_CREATE
);
}
}
