i'm trying to modify the validation of my registration form to stop users from entering spaces and blank info. can you help? here's my script...

Code:
if (
		$username_check == "" &&
		$passwd 		== "" &&
		$email_check 	== "" 
		) {
		$all_fields_empty ="register for free";
		return $all_fields_empty;

cheers
 
learning regex is fun, or at least knowing it is. I'm relatively new to it, but I can tell you it's the best there is for form validation. That said, matching a white space doesn't require regex.
Code:
if (strpos($username_check, " ") && strpos($passwd, " ") && strpos($email_check, " ")){
// have some fuuun!!
}

aron2 - your strpos code would catch whitespace inside a username or pwd, which might be (and usually is) legitimate.
