How to Exclude Specific Categories from WordPress RSS Feed

// Exclude Category with ID 17 from RSS feed
function exclude_feed_category($query) {
	if ($query->is_feed) {
		$query->set('cat', '-17');
	}
	return $query;
}
add_filter('pre_get_posts', 'exclude_feed_category');

 

4. XML Sitemap & Google News에서 제외

- 불가. 하지만 1,2에서 noindex, nofollow 처리했기때문에 큰 의미없음.

5. 검색결과에서 제외

 

// Exclude specific categories from search result page of wordpess
function wpb_search_filter( $query ) {
	if ( $query->is_search && !is_admin() )
	$query->set('cat','-3339,-2415');
	return $query;
}
add_filter('pre_get_posts', 'wpb_search_filter');
