I have an events calendar, which stores events in a mysql database by timestamps. (1226469600 = 12 nov 2008)
Now I need a second calendar which checks the database for events when a user picks a date through 3 select boxes. 3 select boxes with day, month and year. When the select boxes are set, a result will show at the bottom. (no datepickers, I need 3 select boxes!)
Is there a possibility to return an error when the user picks a date that doesn't exist?
How do I check the timestamp from these 3 boxes and return the result at the bottom?
