Subid Help!

I'm trying to set up subid keyword tracking. Here is what I have done so far, but it does not seem to be working..

I pasted this in my php file in between my head tags:

<?php
//grabs the subid and sets $OVKEY equal to it.
if(isset($_GET[’OVKEY’]))
{
$cid = $_GET[’OVKEY’];
}
?>

<?php
//grabs the subid and sets $cid equal to it.
if(isset($_GET[’cid’]))
{
$cid = $_GET[’cid’];
}
?>​

And then I altered my links on my CPA network as such:

http://cpanetwork.com/xxxxx?sub=<?php echo $OVKEY; ?>"​

And lastly I went into Adwords Editor and changed my destination URL for each keyword as follows:

http://mylandingpage.com/index.php?cid={001}
http://mylandingpage.com/index.php?cid={002}
http://mylandingpage.com/index.php?cid={003}
etc.
etc.
​

001, 002, 003, etc are obviously relevant to my own keywords.

Now when I log into my cpa network all that it shows in the Subid Report is:

< No Subid >​

Any help would be appreciated.
Thanks

 

In the first part I think you made a mistake :
$cid = $_GET[’OVKEY’];

You meant
$OVKEY = $_GET[’OVKEY’];

No?

In fact I believe what you need is simply:

<?php
//grabs the cid and sets $OVKEY equal to it.
if(isset($_GET[’cid’]))
{
$OVKEY = $_GET[’cid’];
}
?>
in order to grab the cid from the adword link and then in your page, you alter your CPA links like this:
http://cpanetwork.com/xxxxx?sub=<?php echo $OVKEY; ?>

That's the id
