Hi,

While editing a booking, gives the option to remove an item or change the date/time on it.

But there is no option to add a new item to the booking.

How do I add the option to add items to existing bookings while on the editing page?

Hello, component has no this functionality.

If I want to implement this functionality, where would I start?

To remove an item on a reservation --> "view_reservation_submitbutton.js" has the "function removeReservationItem(id, rid)" which goes into --> \administrator\components\com_booking\controllers\reservation.php through a request and uses the "function remove_item_db()".

In the same reservation.php I see a "function add_continue()" with the description of: "Add item(s) to current reservation and continue."

Would this function e.g. be able to do the job?

Hello, the most important is function BookingModelCustomer::isAdmin in the file /administrator/components/com_booking/models/customer.php. This function decides if logged user is global manager or no.

Ok, lets say Global Manager is set for the user in Artio backend already, how would I go from there to implement the functionality to add items to an existing reservation?

Hello, sorry, but it is very difficult and it is out of user support.
