Can I add a querystring value to the form link to track where users found the link to my form?

I see that there is a widget that can be added to forms to track the referrer.  But I want to publish QR codes in various publications and then track analytics to measure which of several sources resulted in our application form being submitted.

I'm hoping that I may be able to construct unique URLs such as:

https://form.jotform.com/myformnumber?test-20160128 

And then have that querystring logged in the Jotform database.

Is there a way to track links in this way?

Thanks!

You cannot log it in the Jotform database, however you can log it in your own database using PHP.

Here are a couple of guides that may help:
