Passing affiliate variables from user through .htacess to php then redirect

[boogily]

I am trying to set up a system where to link to my site as an affiliate, all you have to do is click www.mysite.com/pals-xxxxxx (where xxxxxx is the affiliate id). I have set up .htaccess with a quick

RewriteEngine on
RewriteRule ^pals-(.*)$ affpass.php?a=$1

and then in my affpass.php I have

<?php
//error_reporting(E_ALL);
//ini_set('display_errors', '1');
$theURL = getenv("HTTP_REFERER");
	
srand((double) microtime() * 1000000);

$aff = $_REQUEST['a'];
	
// redirect to the site now...
header("Refresh: 0; URL=http://newdestination.com/site=mysite&AID=".$aff);


function custom_die($error_msg)
{
	// Nice tidy way of dying
//	echo html_header("Unexpected Error");
//	echo ss_template('error_die.tmpl', array('%error%' => $error_msg));
echo $error_msg;
//	echo html_footer();
	exit;
}


function generatePassword ($length = 8)
{

  // start with a blank password
  $password = "";

  // define possible characters
  $possible = "0123456789bcdfghjkmnpqrstvwxyz"; 
    
  // set up a counter
  $i = 0; 
    
  // add random characters to $password until $length is reached
  while ($i < $length) { 

    // pick a random character from the possible ones
    $char = substr($possible, mt_rand(0, strlen($possible)-1), 1);
        
    // we don't want this character if it's already in the password
    if (!strstr($password, $char)) { 
      $password .= $char;
      $i++;
    }
  }
  return $password;
}
?>

The affiliate ids are not passing. Any ideas why?

Fixed, temporarily. The coding is correct. The affiliate program is being passed to just one product, and I am looking for one that goes to all products. COnsider this solved
