Hice esto
function registerNewUser($username, $password, $password2, $email)
{

global $seed;

if (!valid_username($username) || !valid_password($password) ||
!valid_email($email) || $password != $password2 || user_exists($username))
{
return false;
}


$code = generate_code(20);
$sql = sprintf("insert into login (username,password,email,actcode) value ('%s','%s','%s','%s')",
mysql_real_escape_string($username), mysql_real_escape_string(sha1($password . $seed))
, mysql_real_escape_string($email), mysql_real_escape_string($code));

$result=mysql_query($sql);
/* if (mysql_query($sql))
{
$id = mysql_insert_id();

if (sendActivationEmail($username, $password, $id, $email, $code))
{

return true;
} else
{
return false;
}

} else
{
return false;
}
return false;*/
}
