Hi all!
I finally got to implement the often-demanded categories in the PHP script (http://wikipedia.sourceforge.net/fpw/wiki.phtml).
It works like this: - Add "{{CATEGORY A category,Another category}}" to the text of an article. Separate the categories by ",". - Everything between {{ and }} will *not* be displayed within the text, but as a category list at the bottom of the page, as well as in the sidebar, if you have turned it on. - In an article that *is* a category, write "{{THISCATEGORY}}" somewhere. This will be replaced with a list of all articles which *at that very moment* have a "{{CATEGORY xyz}}" for that category.
See it for yourself at the above site. I put "Gene" and "DNA" into both "Biology" and "Genetics" category. "Genetics" itself is in the "Biology" Category. On the "Genetics" and "Biology" pages, at the bottom, you'll find a grey box, listing all the pages that are within that category.
OK, I know this screams "problems" all over, but it's just the "hooray, it's running!" version. There's much more to be done, starting with a sorted article output to limiting "Search" and "Recent Changes" to certain categories, and so on. But hey, it's a start...
A more technical note: I also put all the "fixed" text displayed on the 'pedia into variables and collected them in one single file. So, for international versions, only one file has to be changed, the other files can get "technical" updates without having to translate/merge the whole thing again.
That's all for now, Magnus
