Hello:),
I am returning to a theatre ticket booking project after about three months and trying to get my head around how to show the prices in a list box (lstTotal).
I have three radio buttons three for three ticket types.
Adult Full
Concession
Friend
When one of these is selected and a seat button is clicked on the seating plan it turns the colour of the corresponding ticket type.
I want to be able to do this for a number of tickets in turn, for them to show in the lstTotal list box and then add up the running total. To do this I know I need to loop through the data base for the correct pricing which depends on the theatre and event but haven’t got a clue which is the best way to go about it … so any pointers will be gratefully received. Thank you.
Below is the code for the booking system and the database for events.
