Reserve service

The class JWeiland\Reserve\Service\ReserveService is the official public API for ext:reserve. You can use this class in your own extension to get some information like remaining participants of a period.

The following example shows a controller that uses FlexForms or TypoScript for Facility and DateTime selection. This selection will be used to get the remaining participants of a matching period.
