Home » Wordpress » Filter for excluding certain categories in WordPress

Put this code in the Functions.php file:

// filter for exluding certain categories
function myFeedExcluder($query) {
if ($query->is_feed) {
$query->set('cat','-12');
}
return $query;
}

add_filter('pre_get_posts','myFeedExcluder');

This will exclude category 12 from your RSS feeds. If you want to exclude more than one category, put them in separated by commas ‘-12,-25,-33′.
