I'm sending a referral form out to my email database and I've got it set up so that their email addresses get passed through and appended to the form URL like this:
http://www.holbrooktravel.com/[email protected]
I've got a hidden field in the form that collects the 'emailid' value and stores it with the responses so they can be matched up with our database.
That's working well, but once someone submits their form they're sent to a thank you page (http://www.holbrooktravel.com/referral-form/thank-you) where they can click a button to go back to the form and refer someone else.
I can't figure out how to keep their 'emailid' value on the 2nd referral so those submissions can be matched up as well. If I'm on the right line of thinking then I need to somehow keep the URL parameters on both the thank you page and the link sending them back to the referral form.
Any suggestions would be very much appreciated!
