          'value' =&gt; 'yes'
      );

          'post_type'           =&gt; 'product',
          'post_status'         =&gt; 'publish',
          'ignore_sticky_posts' =&gt; 1,
          'posts_per_page'      =&gt; $products,
          'orderby'             =&gt; $orderby,
          'order'               =&gt; $order == 'asc' ? 'asc' : 'desc',
