A few fixes: First, place it in an if statement, because you asked to have it fail if there's an error. Second, placing an ! before the ereg() has the if statement kick in if the ereg() statement fails. Third, I'm going to ensure that this ereg evaluates the entire string by placing a ^ at the beginning and a $ at the end if ( !ereg("^[[:alnum:]]$", $string) ) { echo "you've got a problem."; } Enjoy, --Dan -- PHP scripts that make your job easier http://www.analysisandsolutions.com/code/ SQL Solution | Layout Solution | Form Solution T H E A N A L Y S I S A N D S O L U T I O N S C O M P A N Y 4015 7 Ave, Brooklyn NY 11232 v: 718-854-0335 f: 718-854-0409
