如何将woocommerce类名添加到最畅销产品中

Question

如何在woocommerce的顶级产品中添加“畅销书”的类名？

是否有检查产品是否畅销的功能？

Answer 1

我做到了。这是解决方案; 首先，我生成了一个查询，它获得了10个具有最大total_sales的产品

$query = "SELECT ID FROM {$wpdb->posts} p
        INNER JOIN {$wpdb->postmeta} pm ON ( pm.post_id = p.ID AND pm.meta_key='total_sales' )
         WHERE p.post_type = 'product'
         AND p.post_status = 'publish'
         ORDER BY pm.meta_value+0 DESC
         LIMIT 10";

         $topselled_ids = $wpdb->get_results( $wpdb->prepare($query,OBJECT ));
         //print_r ($topselled_ids );
         foreach  ($topselled_ids as  $one_topselled_id)
         $topselled[] =  $one_topselled_id->ID;

然后我检查了当前产品的id是否在数组中（在content-product.php中）。

if ( in_array($post->ID, $topselled) )
$classes[] = "top_selled";
