[SOLVED] preg_match accepts + although It shouldn't

[DEVILofDARKNESS]

this is the regex-string:

/^[A-Za-z][a-zA-Z0-9_]*$/

When I fill in: pe0011P++S

it accepts it

how comes?

it doesn't.  your problem is somewhere else.

That's weird because only if functions.php gives a value AA to $error the user will be added:

<?php
function nation_check($nationname,$username){
$error = "AA"; // All Allowed
if (preg_match("/^[A-Z][a-zA-Z]*$/", $nationname, $matches)) {
	$query = "SELECT nation_id FROM nations WHERE nation_name = '$nationname'";
	$result = mysql_query($query);
	if(mysql_num_rows($result) == 1){
		$error = "NNA"; // Nation Not Avaible
	}
}else{
	$error = "NNNA"; // Nation Name Not Allowed
}
if (preg_match("/^[A-Za-z][a-zA-Z0-9_]*$/", $nationname, $matches)) {
	$query = "SELECT user_id FROM users WHERE user_name = '$username'";
	$result = mysql_query($query);
	if(mysql_num_rows($result) == 1){
		$error = "UNA"; // User Not Avaible
	}
}else{
	$error = "UNNA"; // User Name Not Allowed
}
return $error;
}
?>

my guess is in your 2nd preg_match you are checking $nationname instead of $username.

AH you're right (you always are probably ,)

How stupid I didn't see that

 

Thanks
