Re: Validating form field text input to be a specificvariable type

I don't think so, Wouldn't be better if ctype_digit() return false on an empty string?? any way an empty string is not a digit. This change will brake backward compatibility so it is not an option. if you look carefully the function that you propose is doing two things at once... at this level this is not a good idea. -William El mi? 07-04-2004 a las 12:39, Red Wingate escribió: > No, as this would be yet another line of source.
