Add referrer URI to desitnation URL string

[Stefan83]

I'm using the mobiledetect.net script to redirect mobile users to a mobile page. I'd like to dynamically add the referrers URI to the URL string ie /?source=previous-page. For example, when visiting http://mainsite.com/landing-page you are redirected to http://www.mobiledomain.com/?source=previous-page

Is this possible?
 

<?php
@include("Mobile_Detect.php");
$detect = new Mobile_Detect();

if ($detect->isMobile() && isset($_COOKIE['mobile']))
{
$detect = "false";
}

elseif ($detect->isMobile())
{
header("Location:http://www.mobiledomain.com/");
}
?>

Not sure but maybe

$source = '';
if(isset($_SERVER['REQUEST_URI']) && $_SERVER['REQUEST_URI'] != '/')
   $source = '?source=' . $_SERVER['REQUEST_URI'];
header("Location:http://www.mobiledomain.com/$source");

Now $_GET['source'] will contain the request url before being redirected to your mobile site.

You'll want to urlencode the url in the query string.

$source = '?source=' . urlencode($_SERVER['REQUEST_URI']);

just in case there are any "special" characters in it.

 

Do you want the url of the page that is doing the redirect (which is what Ch0cu3r's code gives you)? Or do you want the url of the the page they came from to get to the page that is doing the redirect? In the second case, use $_SERVER['HTTP_REFERER'] instead of 'REQUEST_URI'.

That's great, thanks guys. Almost there, but it returns ?from= twice and the current page in the string as well.

 

So the URL for the landing page is http://mobiledomain.com/mobile/?from=%2Fmobile%2F%3Ffrom%3D%252Fpassengers%252Ftaxybikes%252F

 

My code is

<?php
include('Mobile_Detect.php');
$url = get_bloginfo('url');
$detect = new Mobile_Detect();

if ($detect->isMobile() && isset($_COOKIE['mobile']))
{
$detect = "false";
}

elseif ($detect->isMobile())
{
$source = '';
if(isset($_SERVER['REQUEST_URI']) && $_SERVER['REQUEST_URI'] != '/');
   $source = '?from=' . urlencode($_SERVER['REQUEST_URI']);
header("Location:http://mobiledomain.com/mobile/$source");

}
?>

ANy ideas why that is?

 

Thanks

Ok, I've got it. It was becuase the script was loading in the header of the wordpress file so there was repitition. Thanks for your help
