Integrating the cForms plugin with the WP Affiliate Software to design a Pay Per Lead Affiliate Model
This integration was done and documented by Yvette Kwei from www.magnumip.com.au
Little Background
I created a form with the popular Cforms II plugin (version 11.1).
In my form, users enter their contact details and then choose between one of four packages that I offer ("Basic", "Standard", "Premium" and "Custom"). Each package has a different price (in this example, $95, $195, $295, and $395). I wanted to pay my Affiliates for sending me these leads. Further, I wanted the "Unique Transaction ID" in WP Affiliate to be the ID given by Cforms to the particular submission.
The Integration Steps
1. Insert the following code into the "my-functions.php" file within cForms:
##### Start code here:
function my_cforms_action($cformsdata)
{
if (!empty($_SESSION['ap_id'])) $referrer = $_SESSION['ap_id'];
else if (isset($_COOKIE['ap_id'])) $referrer = $_COOKIE['ap_id'];
if (!empty($referrer))
{
$email = $cformsdata['data']['Email'];
$txnid = $cformsdata['subid'];
$itemid = 'Unknown';
$amount = 0.0;
$item = $cformsdata['data']['Type of Service'];
if (strpos($item, 'Basic') === 0) { $amount = 95.0; $itemid = 'Basic'; }
else if (strpos($item, 'Standard') === 0) { $amount = 195.0; $itemid = 'Standard'; }
else if (strpos($item, 'Premium') === 0) { $amount = 295.0; $itemid = 'Premium'; ...
