UTM Values Not Capturing Consistently
I am capturing UTM parameters in hidden fields on Marketo forms via cookie. Recently we noticed that some of users UTM values are not being captured in the hidden fields even though the UTM parameters are in website cookies. We reviewed the java script for the cookie code and its storing the values.
Does anyone know if there's a problem or if there are any bugs related to the forms in Marketo?
These are some failed tests below:
<script>
function setCookie(cname, cvalue, exdays) {
var existingValue = getCookie(cname);
if (existingValue !== cvalue) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires=" + d.toUTCString();
var domain = "; domain=." + window.location.hostname.split('.').slice(-2).join('.');
var secure = "; Secure"; // add secure attribute
var sameSite = "; SameSite=Strict"; // add SameSite attribute
document.cookie = cname + "=" + cvalue + ";" + expires + ";path=/" + domain + secure;
}
}
function getUTMParam(param) {
var queryString = window.location.search;
var urlParams = new URLSearchParams(queryString);
return urlParams.get(param);
}
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 "";
}
