From the input - after is is sent from his form.

No, because he isn't setting them until after the form has been
displayed and the user has made his selection.

No, it is NOT a good idea to add a row every time the page is displayed.
Wait for the user to respond to the request, then add it to the
database, as he is already doing.

He needs to do other validation on the data also, but first he needs to
get this part working.

BTW - your sig separator is broken. It needs to be exactly
hyphen-hyphen-space-newline.
