Feedback form based on QR codes
-
I created a form on my WordPress website (using the WPForms plugin) to allow people who drink my beers to leave feedback.
I would like to add QR codes to the labels of my beers with the following features:
– Make the feedback page only accessible through the QR code (no direct access through URL)
– Retrieve two GET variables from the QR code link (Beer name and lot number) and display them at the top of the form as some sort of title
– Prevent people from submitting the form again, based on IP I guess. Otherwise, I would have to print a unique QR code on each label
– Optional: retrieve a date from the QR code (= when the beer was bottled) and compare it with the date the feedback was submitted, so I can know how old was the beer when it was tastedThanks
