How to add another parameters to WP_Query?

Question

You can use below code to add other two parameter as condition.

  $args = array(
      'posts_per_page' => $postsCount,
      'post_type' => $postsType->name,
      'order' => 'DESC',
      'orderby' => $postsOrder,
      'taxonomy' => $postsTaxonomy,
  );

  $postsOrder = get_sub_field('posts-ordering');

  if ($postsOrder == 'post_views_count') {
      $args['meta_key'] = 'post_views_count';
      $args['orderby'] = 'meta_value_num';
  }
  $query = new WP_Query($args);
