Note Submitter: retry at whatnet dot org ---- Here's something to help out all the nubs -- a nice email validation regex. It doesn't handle IP addressed domains, but who cares. It allows . and - characters but not as leading or trailing chars. It also won't allow repeats of said chars. will match: u.r.teh.sux0r@hotmail.com won't match -blah-@blah.u.go.girl.com or bla--h@red.herrning.net peace out -- retry NOTE: remove the spaces in the regex function checkEmail($email) { if ( !preg_match( "#^[\w|\d] +(([\-|\.][\w|\d]+)+) ?@([\w|\d|\-]+\.)+[\w]{2,3}$#" , $email) ) return 1; return 0; } then use it like this in your scripts: if ( checkEmail($instanceEmail) ) $errormsg = "Your email address blows.";
