Alphabetize All Categories Except News & Events plugin

After writing my previous post where I alphabetize all categories site wide except the ‘news-events’ slug it seemed appropriate to do the same thing as a very simplified plugin. Everything from that post remains the same except I’ve added a plugin header to provide information to WordPress about the plugin.

add_action( 'pre_get_posts', 'joseph_dickson_change_sort_order');
function joseph_dickson_change_sort_order($query){

	if(is_category('news-events')) {

		// Set the order to DESC descending
		$query->set( 'order', 'DESC' );

		// Set the orderby date so it loops newest to oldest posts
		$query->set( 'orderby', 'post_date' );

	}

	elseif( !is_category( 'news-events' )) {

		//Set the order ASC ascending
		$query->set( 'order', 'ASC' );

		//Set the orderby title so it loops A-Z
		$query->set( 'orderby', 'title' );

	}

};
