How to track data using cookies in pardot

Simply add this script into JS file and change the cookies name with your own requirements and append these cookies with Pardot form fields.

function getCookie(cname) {
let name = cname + “=”;
let decodedCookie = decodeURIComponent(document.cookie);
let ca = decodedCookie.split(‘;’);
for(let i = 0; i <ca.length; i++) {
let c = ca[i];
while (c.charAt(0) == ‘ ‘) {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return “”;
}

let searchParams = new URLSearchParams(window.location.search);
var d = new Date();
d.setTime(d.getTime() + (24*60*60*1000));
var expires = “expires=”+ d.toUTCString();
let source;

if( getCookie(“_utm_source”) == ” ) {
if(searchParams.has(‘utm_source’)){
//console.log(“Search Param Cookie: “, searchParams.get(‘utm_source’) );
document.cookie = “_utm_source=” + searchParams.get(‘utm_source’) + “;domain=citrusbits.com;” + expires + “;path=/”;
}
else {
let prevKey = document.referrer;

if( prevKey == ” || prevKey == undefined ) {
prevKey = “Direct Browser”;
}
else {
let prevKey = document.referrer.split(‘/’)[2].replace(‘www.’,”);

prevKey = prevKey.substr(0, prevKey.indexOf(‘.’));
prevKey = prevKey.toLowerCase().replace(/\b[a-z]/g, function(letter) {
return letter.toUpperCase();
});
}

document.cookie = “_utm_source=” + prevKey + “;domain=citrusbits.com;” + expires + “;path=/”;
}
}

if( getCookie(“_utm_medium”) == ” ) {
if(searchParams.has(‘utm_medium’)){
document.cookie = “_utm_medium=” + searchParams.get(‘utm_medium’) + “;domain=citrusbits.com;” + expires + “;path=/”;
}
else {
document.cookie = “_utm_medium=N/A;domain=citrusbits.com;” + expires + “;path=/”;
}
}

if( getCookie(“_utm_campaign”) == ” ) {
if(searchParams.has(‘utm_campaign’)){
document.cookie = “_utm_campaign=” + searchParams.get(‘utm_campaign’) + “;domain=citrusbits.com;” + expires + “;path=/”;
}
else {
document.cookie = “_utm_campaign=N/A;domain=citrusbits.com;” + expires + “;path=/”;
}
}

if( getCookie(“gclid”) == ” ) {
if(searchParams.has(‘gclid’)){
document.cookie = “_gclid=” + searchParams.get(‘gclid’) + “;domain=citrusbits.com;” + expires + “;path=/”;
}
else {
document.cookie = “_gclid=N/A;domain=citrusbits.com;” + expires + “;path=/”;
}
}

if(searchParams.has(‘utm_source’)){
source = ‘utm_source=’;
}
else {
source = ‘source=’;
}

let formFilledOn = window.location.href.split(‘?’)[0];
let formSrc = jQuery(“iframe.pardotform”).attr(“src”);
var params = ‘?’ + source + getCookie(‘_utm_source’) + ‘&utm_Medium=’ + getCookie(‘_utm_medium’) + ‘&utm_campaign=’ + getCookie(‘_utm_campaign’) + ‘&form_filled_on=’ + formFilledOn + ‘&gclid=’ + getCookie(‘_gclid’);

jQuery(“iframe.pardotform”).attr(“src”, formSrc + params);
