Limit feed to one category

Hi @ahni,

Yep absolutely, if you add something like the code below to your theme’s functions.php then simply change the 5 to whatever the ID of the category is you wish to restrict it to.

if ( ! function_exists( 'wpna_restrict_feed_category' ) ) :

	/**
	 * Modifies the main RSS query.
	 *
	 * @param  WP_Query $query
	 * @return $query
	 */
	function wpna_restrict_feed_category( $query ) {

		// Requested option name, / value to default to.
		if ( function_exists( 'wpna_get_option' ) ) {
			// get the feed slug.
			$feed_slug = wpna_get_option( 'fbia_feed_slug' );

			// If it's the Instant Articles feed
			if ( $query->is_feed( $feed_slug ) && $query->is_main_query() ) {
				// Restrict to only show posts in a certain category.
				$query->set( 'cat', 5 );
			}
		}

		return $query;

	}
endif;
add_filter( 'pre_get_posts', 'wpna_restrict_feed_category', 11, 1 );

Thanks

Going to assume this did the job, let me know if not.
