Question

WooCommerce的特色产品小部件具有选定的ID，但只有一个产品退货。

我的目标是我有一些产品ID，例如1202,125,2152,885,1254，需要将它们显示为列表

我制作了一个metabox，可以在其中选择产品并获取ID并将其存储为$featured $featured返回的输出类似于1202,125,2152,885,1254。

我使用$query_args['post__in'] = array($featured);，但结果仅输出一种产品，而不是所选的5种产品。

有人可以帮我吗？

如果在使用$featured时将值作为数组传递给$featured = get_post_meta($post->ID, '_blog_feature_product',true);变量然后，您不需要使用此

$featured = implode( ',', array_map( 'absint', $featured ) ); 
$query_args['post__in'] = array($featured);

只需使用以下内容即可：

$query_args['post__in'] = $featured;

如果值以逗号分隔即$featured传递给$featured = "1,2,3,4,5";

然后使用此

$query_args['post__in'] = explode( ",", $featured);

现在应该可以正常工作了。

Woocommerce产品ID列表仅返回一个产品，而不是多个产品
