I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input.
What do I need to learn to make a website to do this? Will javascript do the trick?
I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.
This could be a reasonably simple application built in PHP (supported by almost all web site hosters) that processes input fields and returns a text file. No database necessary in case the application doesn't need some persistent memory on earlier input or results. There's a lot of PHP learning material available on line - with some programming experience you should be able to have some prototype working in one/two day(s).
