Question

I have a business profile set up with a separate gallery page. The header for these pages is a php include.

I am trying to set up a breadcrumb trail for this profile so am using http_referer to track which listings page I came from.

if ($title == 'Business Profile'){
session_start();
$referer = $_SERVER['HTTP_REFERER'];
}
?>

The problem I have is passing the http_referer as a variable from the business profile to the gallery page. How would I do this so that I can link back to the listings page from both the business profile and the gallery? If I use http_referer on the gallery page it will only take me back to the profile I came from.

You could use cookies? For example on your landing page;

if(!isset($_COOKIE['HTTP_REFERER']))
{
    $expiryTime = time()+(60*60*24); // Set to expire after 1 day
    setcookie('HTTP_REFERER',$_SERVER['HTTP_REFERER'],$expiryTime,'/');
}

And then on all other pages you can detect if there is a cookie already set;

if(isset($_COOKIE['HTTP_REFERER']))
{
    $referer = $_COOKIE['HTTP_REFERER'];
}
