Add session variable for 3rd party referrer?

Recommended Posts

Sorry, I've done a lot of searching but can't tell if this is standard fare that I don't quite understand, or if it's something not very common or easy to do with OSC.

 

We're setting up our site to receive hits from various referrers, and it needs a session variable to track where the click came from, and that that user followed their visit through to a purchase. So the string coming from the referrer (say "Some Company" with ID # ABC123) is something like ?referrerName=SomeCompany&refID=ABC123... i.e.

 

http://www.mystore.com/catalog/index.php?referrerName=SomeCompany&refID=ABC123

 

How do I add this URL string or set a session variable, so EVERY page the whole time I'm browsing retains that string? i.e.

 

http://www.mystore.com/catalog/product_info.php?cPath=22_31&products_id=43?referrerName=SomeCompany&refID=ABC123
http://www.mystore.com/catalog/checkout_shipping.php?referrerName=SomeCompany&refID=ABC123

 

From what I've gathered it sounds like it's something in application_top.php, but I just can't quite figure out what. Hopefully it's simple and straightforward, common practice for someone else! :) Any help on this would be great. Thanks!

One way:

 

In /catalog/includes/application_top.php before this code:

 

// set SID once, even if empty
 $SID = (defined('SID') ? SID : '');

 

Add this code (modify it to include your referrer names and ID's):

 

  $link_refs = array(
"Acme" => "a1b2c3",
"Nutz-R-Us" => "f9c4l5",
"Edsel"  => "h9k73b",
"WhoozWho" => "q9z5g4",
"PartsIzParts"  => "u2m3r1");

 if ( $referrerName = $_GET['referrerName'] ) {
   if ( $refID = $_GET['refID'] ) {
     if ( $link_refs[$referrerName] != "" ) {
       if ( ! tep_session_is_registered('referrerName') ) {
         tep_session_register('referrerName');
         $refID = $link_refs[$referrerName];
         tep_session_register('refID');
       }
     }
   }
 }

 

That part identifies and registers the referrer names and ID's.

 

To include them in the links this code in /catalog/includes/functions/html_output.php

 

////
// The HTML href link wrapper function
 function tep_href_link($page = '', $parameters = '', $connection = 'NONSSL', $add_session_id = true, $search_engine_safe = true) {
   global $request_type, $session_started, $SID;

 

Change the last line in that code to this:

 

    global $request_type, $session_started, $SID,$referrerName,$refID;

 

Then in that same function BEFORE this code:

 

    if (isset($_sid)) {
     $link .= $separator . tep_output_string($_sid);
   }

 

Add this code:

 

    if ( tep_session_is_registered('referrerName') ) {
     $link .= $separator . "referrerName=" . tep_output_string($referrerName);
     $separator = '&';
   }

   if ( tep_session_is_registered('refID') ) {
     $link .= $separator . "refID=" . tep_output_string($refID);
   }

 

This worked in a test area I have.

If I suggest you edit any file(s) make a backup first - I'm not perfect and neither are you.
