Use Category RSS
Here’s a simple quick hack that lets you have RSS feeds from each of your sites categories. While this does need to be done to all themes used, thats not a big deal and it does bring a very nice bit of functionality to the website.
Locate the theme folder you are using and edit the ’sidebar.php’ file within the folder.
Add this code to the list:
<?php if (get_query_var('cat')) { ?> <li> <a xhref="/wp-rss2.php?cat=<?php echo get_query_var('cat'); ?>"><?php echo single_cat_title(); ?> (RSS)</a> </li> <?php } ?>
Now save the file - done.
To access the feeds, use a url pattern such as:
http://theworldsfullof.us/?feed=rss2&cat=10
That’s all there is to it, you can use the url to RSS2 syndicate categories. This is especially handy when you have multiple topics of site content!
