How do I write a regular expression which matches number-alphabets and commas only?I came out with this one below but it doesnt work - it accepts other punctuation marks as well!\[code\]# check for matches number-alphabets and commas only if(!preg_match('/([a-zA-Z0-9]|[a-zA-Z0-9\,])/', $cst_value)) { $error = true; echo '<error elementid="usr_username" message="'.$cst_name.' - please use number-alphabets and commas only."/>'; }\[/code\]Many thanks,Lau
