NOTE:

EXAMPLE OF HOW IT SHOULD LOOK LIKE ONCE ADDED TO THE PAYPAL BUTTON EMBED CODE. OSI TRACKING CODE IS THE BOLD TEXT. DO NOT USE:

<form action="http://www.paypal.com/cgi-bin/webscr" method="post">
<input name="cmd" type="hidden" value="_s-xclick" />
<input name="hosted_button_id" type="hidden" value="XXXXXXXX" />
<input alt="PayPal - The safer, easier way to pay online!" border="0" name="submit" src="http://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif" type="image" />
<img alt="" border="0" height="1" src="http://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" />
<input name="notify_url" type="hidden" value="https://ninademo.ositracker.com/sales/paypal_plugin" />
<input id="custom" name="custom" type="hidden" />
<script language="JavaScript" src="https://ninademo.ositracker.com/sales/get_affiliate" type="text/javascript">
</form>

Step 5. Add the code below right before the closing body tag of your website landing page. Note, this should get added to the page that people go to when they click on an affiliate link.

<script type="text/javascript">

function setCookie(cname,cvalue,exdays) {

    var d = new Date();

    d.setTime(d.getTime() + (exdays*24*60*60*1000));

    var expires = "expires=" + d.toGMTString();

    document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/";

}

var urlParams;

(window.onpopstate = function () {

    var match,

        pl     = /\+/g,  // Regex for replacing addition symbol with a space

        search = /([^&=]+)=?([^&]*)/g,

        decode = function (s) { return decodeURIComponent(s.replace(pl, " ")); },

        query  = window.location.search.substring(1);

    urlParams = {};

    while (match = search.exec(query))

     urlParams[decode(match[1])] = decode(match[2]);

    if (urlParams['affiliate_id']) {

        // alert('affiliate_id = '+urlParams['affiliate_id']);

        setCookie("affiliate_id", urlParams['affiliate_id'], 60);

    }

    if (urlParams['prodgroup']) {

        // alert('prodgroup = '+urlParams['prodgroup']);

        setCookie("prodgroup", urlParams['prodgroup'], 60);

    }

})();

</script>

Step 6. Add the code below to the same page that your PayPal button is on. Thie code shown below should be right before your closing body tag.

<script type="text/javascript">

function getCookie(cname) {

    var name = cname + "=";

    var decodedCookie = decodeURIComponent(document.cookie);

    var ca = decodedCookie.split(';');

    for (var i = 0; i < ca.length; i++) {

        var c = ca[i];

        while (c.charAt(0) == ' ') {

            c = c.substring(1);

        }

        if (c.indexOf(name) == 0) {

            return c.substring(name.length, c.length);

        }

    }

    return "";

}

var affiliate_id = getCookie("affiliate_id");

var prodgroup = getCookie("prodgroup");

if (affiliate_id != "" && prodgroup != "") {

    var hidvar=affiliate_id+'@'+prodgroup;

    var x = document.getElementsByName('custom');

    for (i=0; i<x.length; i++) {

        x[i].value=hidvar; 

    }

}

</script>
