Help - Handling a form

[SJones]

I have a form that is asking for a code to be entered.

<form action="handle_form.php" method="get" name="affiliate_code" id="affiliate_code">
<p><b>Enter Affiliate Code</b>
<input name="code" type="text" size="6" maxlength="6">
</p>
<p>
<input type="submit" name="Submit" value="Submit">
</p>
</form>

This is where I need help, I would like to define three constants

define('CODE1', 'http://www.mysite.com/customer_abc.php');
define('CODE2', 'http://www.mysite.com/customer_xyz.php');

define('CODE3', 'http://www.mysite.com/customer_123.php');

I want to take the input name from the form and compare it to a predifined constant. And if it matches, then go to that URL - if it does not match I would like to go to a failure.php page. I am just learning php any coding help for the handle_form.php would be greatly appreciated

Hey, not sure if your approach is bang on but I think this is what you're thinking of.

switch($_GET['code']) {
  case 'CODE1':
    header('Location: '.CODE1);
    break;
  case 'CODE2':
    header('Location: '.CODE2);
    break;
  case 'CODE3':
    header('Location: '.CODE3);
    break;
  default:
    die('Invalid code');
}
?>

I made a mistake! First I need to have the code from the form match a defined code
define('CODE1', 'abc');
define('CODE2', 'xyz');
define('CODE3', '123');

the locations would be
CODE1 = 'http://www.mysite.com/customer_abc.php'
CODE2 = 'http://www.mysite.com/customer_xyz.php'
CODE3 = 'http://www.mysite.com/customer_123.php'

Any ideas on how I can code this?
