I recently wanted to remove a specific category from my WordPress RSS feed. In my case, I wanted to create a short podcast that wasn't part of our normal podcast schedule, and I didn't want the program to find its way into iTunes and other podcast syndication sites.
Copy and paste the WordPress function into your theme's functions.php file or, if you sensibly have one installed, your custom functions plugin.

<?php
2
/*
3
Remove Category From WordPress RSS Feed

http://www.beliefmedia.com/code/wp-snippets/remove-category-rss

*/
6
7
function beliefmedia_category_rss_filter($query) {
8
if ($query->is_feed) {
9
$query->set('cat','-3');
10
}
11
return $query;
12
}
13
You will have to change the '-3' on line 3 to correspond to the category that you don't want to appear in your feed.
To determine the category that you want to eliminate, you will have to mouse over the category and note the ID number that will appear in footer of your browser.
