Call model-class from view

A man's tools are only as good as the man using them. If you don't like the way something works, improve on it. That's how CodeIgniter is designed to work.

As for frameworks, there are a lot out there to choose from, it depends on your needs. Personally, I recommend CodeIgniter (of course). It's neat, fast, easily extendible, but that's my preference. Also, it has one of the best documented thing I've seen (including most non-framework related docs).[/quote]

I agree that CodeIgniter got an incredible user guide and the code is very well documented, no doubt! That's the reason I downloaded CodeIgniter in the first place.

What I need to do is:

I got my login-form on every singel page of my website. That form shall call for the same Controller which validates the data and gives you 1) welcome message if you login successfully. 2) give you an error message if you fail. The content of the website shall be the same so I do not want you to get redirected to the mainpage or something. I don't know how to do this. If you know any code example or something I'd gladly look at it!
