Sorry about confusing title but let me explain what I'm trying to do.
I'm creating an online form in a plugin which allows the user to enter some values. Once they click on submit the new page should open which is a PDF page and their values that they entered show in it.
I will generate PDF from HTML but which page and how I can open new page in plugin as that page might not exists in few peoples's site
Maybe my way is bit wrong but please give suggestion or solution if you know.
