This is really a data validation problem and is best handled 
BEFORE the data goes into the database. Presumably, you have 
some sort of CGI script that accepts the data from the form, 
possibly processes it and then puts it in the database. This 
is probably the place to validate the data. If anything fails 
the form can be represented...
