Form URL redirect based on freetext answer

Hello,

Im looking for a way to redirect to a custom url based on a form submission. I've seen previous code snippets based on a dropdown box but i'd like to be able to edit a URL without predetermined form answers.

For example, if the user submited two entrys into a form with two text boxes: "example" and "example2" it would redirect to "www.website.com/example/example2. This is without knowing what they might put in beforehand.

I havent got a website to refer to at the moment im afraid, so just looking to be pointed in the right direction.

Thanks!
