Cancel that, i don't think thats true

Should work i think

Gr,

Try
if(!ereg("^([a-zA-Z]{4,20})\$", $_REQUEST['f_name'])) {

Added the $ at the end else the could be more then 20 chars

What's wrong with the following regular expression? As far as I can se, only alphabetic characters including the special swedish ones, should be let through, but whatever character passed on in $_REQUEST['f_name'] passes the test?

if(!ereg("(^[a-zA-Z]{4,20})", $_REQUEST['f_name'])) {
error("Your first name should be between 4 and 20 alphabetic characters");
}

The next one, used to check valid birthday dates, work. And I can't see where they differ!

if(!ereg("([0-9]{4})-([0-9]{2})-([0-9]{2})", $_REQUEST['birthday']))

Br,
