title: Passing Google Analytics Tracking info via forms
body: <p>Lets say I have a customer who comes into my website through a google analytics tagged link (with utm_campaign, utm_source, utm_medium etc added).</p>
  
  <p>They click around the site on a few different pages, then fill in a form.  The utm_ values no longer show in the URL on the form page.</p>
  
  <p>Is there any way for me to get those values (utm_campaign, utm_source, utm_medium) so I can populate hidden fields in my form, and track the campaign source of these leads in my CRM?  Can I use JavaScript to read the Google Analytics cookie to extract these?</p>
  
  <p>We have a large website with thousands of products and dozens of forms, so something that I can implement on the forms would be ideal. </p>
