HTTP REREFER and redirect prob

[Anon]

I am setting up a simple securtiy project. Each page that requires security include a file called called security.inc. This include checks the PHP_SELF variable against a row in my DB and say yes or no. If no i want to redirect to a access denied page but with a link to the refering page. Here is my code:

securuty.inc

$refer = getenv("HTTP_REFERER");

IF NO>

header("Location: http://193.193.113.21/security/admin_error.php?errortype=1&referer=$refer");
exit;

It redirects fine but with no value in the querystring for refer. If i replace the $refer variable with some text or even a web address that passes fine.

Any ideas?

Cheers
Marcus

have you tried.
not have the variable in the string it wont work in any language i worked in but i quite new in php. Instead concatinate it, i tink you do it with . in php ?

IF NO>
$redstr "Location :http://193.193.113.21/security/admin_error.php?errortype=1&referer='";
$redstr = $redstr.$refer."'";
header($redstr);
exit;
