So my problem is this:
I need my users to book the delivery date that they want their products on an event calendar that has a finite number of slots per day. This is important because I can't get overrun with too much demand one any one day, That way I can smooth my demand, plan my production and get more capacity if I see demand growing in the future.
I've already set up a form for my users to register using Gravity Forms - no problem there
I also have a plugin called Booking Calendar where users can book to a specific date.
My concern is I will not be able to integrate Booking Calendar within Gravity forms, which means I have to set up two entry forms pages and customers will have to enter the same information twice.
So instead, I think a solution could be to have a LOGIN functionality where customers create a profile. That way I think all the customer data from both types of form could reside under the same user account - at least I think in theory.
My question, then, is how to create the login functionality. Can you give me any suggestions?
