I have three select'a. In the first: day. In the second: a month. In the third: a year. I would like these selects to be entered into the database as a single integer (date). But no matter how I tried - it does not work. This thing is needed for registration (date of birth of the user).
How do these three select'a merge into one to bring in the database? Or just to score and remove these selects?
