Good morning,

I have the following on
http://www.barbaraling.com/rediresp.php

<?
if(!$ca){
$ca=1;
} else{
$num = array(
1 => "http://www.auctionupperhand.com/",
2 => "http://www.auctionupperhand.com/recruiting/index.html"
);
}
Header( "Location: $num[$ca]");
?>


I would assume that if $ca is not defined, it would
default to the first option (ie, auctionupperhand).
But it goes to the site on which its hosted
(barbaraling.com).  Might someone point out
where I've been clueless?

Thank you in advance,

Barbara Ling

Hi Barbara,

when your script hits the if-clause without having $ca being initialized, you set $ca to 1 but the array $num remains uninitialized.

Therefore your redirect is something invalid as $num does not exist in this case.


<?
     if(!$ca)
     {
          $ca=1;
     }

     $num = array(
                    1 => "http://www.auctionupperhand.com/",
                    2 => "http://www.auctionupperhand.com/recruiting/index.html"
               );
     
     Header( "Location: $num[$ca]");
?>

Regards
 Niko


PS: Watch out for your php configuration of register_globals when you are passing $ca through a link or form. ($_GET['ca'] or $_POST['ca']).
