Heh.

 

You could easily simplify that to a much smaller page, and easier to work with.

 

/*
create a page form.php which can hold just the form itselfs
  use an array based error system
*/

if(!$_POST['submit']){
include "./form.php";
}else {
# your variables
$username = mysql_real_escape_string($_POST['username']);
$password = mysql_real_escape_string($_POST['password']);
//etc...

$errors = array();

   if(!$username){ $errors[] = "You did not supply a username"; }
   if(!$password){ $errors[] = "You did not supply a password"; }
   #etc

   if(count($errors) > 0){
      foreach($errors AS $error){
      echo $error . "<br>\n";
      }
   include "./form.php";
   }else {
   # register
   }
}
