Limit to specific category not working

Hi Ashley,

I’m trying to limit my archives to single category (“blog”) only but unfortunately I can’t make it. I was trying method from FAQ as well as exluding category (topic found here in support) but neither of these works.

I don’t know if something changed due to updates or am I doing something wrong. Some help will be highly appreciated! Code I dropped into functions.php :

add_filter('expanding_archives_get_posts', function(array $args) {
     $args['cat'] = blog; // Replace with ID of your category.

     return $args;
 });

 add_filter('expanding_archives_query', function(string $query) {
     $category = get_category(blog); // Replace with ID of your category.
     if (! $category instanceof \WP_Term) {
         return $query;
     }

     global $wpdb;

     return "
 SELECT DISTINCT MONTH(post_date) AS month, YEAR(post_date) AS year, COUNT(id) as post_count
 FROM {$wpdb->posts}
          INNER JOIN {$wpdb->term_relationships} ON ({$wpdb->posts}.ID = {$wpdb->term_relationships}.object_id AND {$wpdb->term_relationships}.term_taxonomy_id = blog)
 WHERE post_status = 'publish'
   AND post_date <= now()
   AND post_type = 'post'
 GROUP BY month, year
 ORDER BY post_date DESC
     ";
 });

There are still all posts from all categories visible.

Thanks!

Jakub
