Ummm the ereg format would look something like this:

 

$pattern = '/!|@|#|$|%|^|&|*|\(|\)/'

 

There has to be a better, more effecient, way to do that though....

 

If you're trying to block everything besides a-z A-Z 0-9 and spaces I would suggest something like:

 

$pattern = "/[^a-z0-9 ]/i";
if(preg_match($pattern, $input)) {
//got invalid stuff
}

EEK >_<. Line 31 is your line, btw.

Ahhh my bad... I'm still bad at regexp's ;p.

 

It needed to be:

$pattern = '/[!|@|#|$|%|^|&|*|\(|\)]/';

Pipes are no longer metacharacters inside of character classes; they are not needed.
