I'm starting to get more and more freelance work and I've decided I'd like to make a client area. Nothing too fancy, but I'd like to make a login screen that when details are entered takes them to their specific directory. Can anyone aim me at a tutorial that would help me achieve that, or are there any open source things already available that I can't find.. I have tried to google, but I'm probably looking for all the wrong terms so i'm not coming up with anything useful. Thanks for any help.
I personally used session variables for a similar thing (project management) and a relational database that prevented people from viewing things not related to their group or userid.
