Newbie frustration!

Hello everyone: I started playing around with some php scripts a while ago and became hooked on it. I have a few books but I'm afraid I'm a learn by example kind of person and get stuck at times. While working on my wife's site I made headers, footers, navigation and a little MySQL database for her yarns with a small database administration module and so on. The thing is that I would like to have the site divided into directories by subject and have the same template load every time , but my logic tells me that I have to have an index.php3 per directory and have to do this process every time I add a subject. I would like to spend my time working on one document and add ifs, whiles and elses than doing that. I have read most of the class.Fast.Template, fast.Template stuff, but if there is an example on how to do this I'm missing it. As far as I can tell I can only create one document and I can't find how to manage URLS to other documents with the same template I wish I could get help on this! Rergards: Gerry Figueroa
