Dynamic Logic Queries

I don’t know if I’m barking up the right tree here, but… I’ve set up a bunch of simple text widgets which provide links for people to subscribe to RSS feeds of specific categories I’ve set up in WordPress. Then I’ve isolated each widget to display only on the relevant category page with Widget Logic, e.g.

Widget Content: <a href="Feed URL">image</a> Get [Category 1] updates delivered to your device. Subscribe to the RSS feed in your favourite RSS reader.

Widget Logic: is_category ( 1 ) || in_category ( 1 )

And it works fine.

However, I’d rather not have to do this for every single category that I have set up. Therefore I was wondering whether there is a way to dynamically generate the parameters in the logic statement through PHP. Such that I’m not specifying a category as such, but rather a call to retrieve the category that the viewer is looking at. It doesn’t have to be in a widget – I’m happy and comfortable to edit template files.

Hope that makes sense. Thanks in advance.
