if(preg_match('(.*)^[A-Za-z0-9]+', $_POST['username']) !== 0) {
echo "<p style=\"color:red;font-weight:bold;margin-left:95px\">";
echo "Username must only contain A-Z and 0-9</p>";
include("register.html");
exit;
}
I used the code above but I now get this error message
Warning: preg_match() [function.preg-match]: Unknown modifier '^' in
C:\Documents and
Settings\iceweasel\Desktop\XAMPP\relik.ath.cx\forum\register.php on line 2
I don't like to run php with errors off so I wanna ask how I can fix this.
