[SOLVED] help with reg expression

[RyanSF07]

Hi Guys,

 

I don't understand why the following permits % symbols. Isn't this saying "only allow upper and lower case letters, numbers, underscores, hyphens and/or white spaces"?

 

That's what I'd like it to be --- what am I doing wrong?

 

Thank you for your help ~

 

if (eregi("^[a-zA-Z0-9_\-]|[:space:]*$", $postedString) ) {
$b = TRUE;
} else {
	$b = FALSE;
	$content .= "<p>Letters, numbers, whitespaces, underscores, or hyphens only please.</p>\n";
}

if(preg_match('#^[a-z0-9_\s-]*$#i', $postedString)){
...
