Required items in a form

What I'm trying to do is essentially force a user to fill in required items
in a form, which will be saved to a database. How can I get it so that once
the user clicks "OK" on the dialog box, it transfers control back to the
form, and not save the empty fields into the database?

Follow the golden rule of not trusting user input.

When you get back values for the fields, check them, and if not correct, ask
again, give an error, abort the program, erase the data base, reboot the
system, whatever is appropiate to handle such an error.

What do you mean by "transfers control back to the form"? A form doesn't
have any code, and so can't "control" anything.

Now, it is certainly possible to define an onSubmit handler in the <form>
header, then write a Javascript function that validates the input. If the
function returns false, the submit won't happen.
