I would like to prevent a user from entering "To Be Announced" on a form. I would also like to prevent them from entering any version of that, i.e. "TBA," T.B.A.," "To Be Annc.," etc... The problem is, I have no idea how the user might try to fool the form. What would be the easiest way to prevent the user from entering such text?
I'm looking for something along the lines of:
if ($mystring <> $thisOrThat) {
do my thing;
} else {
go back and do it again;
}
