Hello @krisosterhout,
There are lots of options like IP Address, Date, Post/Page data embeds or you can even record your users’ info (depending on your needs) using the hidden field.
About the Query Parameter value, assume the URL of the form is https://example.com/form/?name=WordPress
Here the query id is “name“. Now when anyone visits the link which has the form in it, it will auto-populate the Hidden field with WordPress
I hope this makes sense. Should you have any doubts or need any help, feel free to reply in the thread below and we would be happy to help!.
Regards,
Prathamesh Palve
