Is there a way to pass URL parameters to hidden fields? I’ve followed this article’s advice of having the parameter getting passed through under the ‘Pre-filling a Form with URL Parameters’ section but I’m not sure if it works for hidden fields.
Yes, this can be done. The key is to make sure your hidden field is named exactly the same as the URL parameter.
So for instance, if your URL is https://example.com/?utm_content=testing123 then you will need a hidden field called “utm_content” with no default value in it and that will grab the value from the URL.
