I'm planning on doing a taxi booking system given the off the shelf ones are too over sized for our needs. One issue I'm having is that at the moment our Excel sheet looks up from our price file, another Excel sheet. We pick a place from list to start from a filtered drop down list, then a destination in another drop down and it fills the price automatically.
Any suggestions on implementing this in Knack please??
I think it is possible to do this using the database alone. You need a Locations Table, a Routes Table (to hold from, to and price) and a bookings table with a From and To fields - the From is a connection to Locations and To is a connection to Routes filtered by the value in the From field.
You then create an initial form which you enter the from and to into:
and a submit rule goes to a child form to add additional information and a Record rule looks up the price:
Finally you have the child form which you can edit the rest of the booking:
This is made up of a Display View to display the route and an Edit view.
