Passing a querystring variable to a hidden field


#1

Is there an easy way through Unbounce to pass the value of a querystring variable in the URL to a hidden field to be submitted with the form? I’ve done this in the past by setting a cookie that follows the user around as they navigate a site but never just pulling right from the querystring.

Any assistance would be greatly appreicated!

Hi Craig, as long as you have a hidden field (or visible field) with the same exact name as the query string in the URL, we will automatically populate the value of that field with the value of the query string. For example, a field in your form named first_name would capture the value of “Carter” if the user accesses your page from the url: yoursite.com/pagename?first_name=Carter

Hope that helps!
