I need to create a simple website/webpage, a questionnaire. So I need to create a webpage that has many forms.
For example, a form asking, "Are you Male or Female?". If "Female" is chosen, I would like a form to pop up below it asking "Are You pregnant?".
But this page will have many more questions.
I know about HTML, but what about the server-side of the coding? What language should I write that in?
Should I start with a designing tool like Dreamweaver?
ASP.NET/C# would probably be most suitable for a site like this, due to ease-of-use, and large support base on the net.
Well.. for server side software you'd want PHP, ASP or ColdFusion. You could probably even find an existing product/script (for free no less) that does what you need. which should you choose? It's up to you whichever feels comfortable. It may come down to hosting cost, in which case if you know where you're hosting, make the decision based on that.
Then you'd -most likely- need some sort of database to store all that data in - unless it's simply a wizard (a set of questions leading to an answer). If you are storing the data MySQL, PostgreSQL are good options, SQLite if you're unlikely to have a giant site.
Before you even consider creating a web site in Dreamweaver, you should first learn the following:
These 5 are the easiest languages (in my opinion) to grasp, and thus the best starting point for web development.
My suggestion would be to start looking at existing solutions. For example, if you need to create web surveys and questionnaires, why to re-invent the wheel and not to use existing software such as Lime Survey, free, open source and in PHP?
Try Google Docs. Sign up, create a spreadsheet, and click on the Forms menu. Minimal coding required, I can't think of a way to do it quicker.
Add questions of different types (text/number/option selection), give the question some text and click Next. Repeat. And you're done!
