What I would really like is to be able to add a button on the confirmation page that can take the client to the calendar for the same class, starting at the same week that was just booked, so that the client can easily book the next session of that class. However as a simpler initial implementation, I’d like to display the last booked date (or perhaps better, the last booked date and class name) in a text box on the booking pages.
I don’t want to implement my own set of booking pages, and would prefer to use keep the javascript very simple. (This would be the first customization of the website.)
