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?

答案 0 :(得分:1)
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。
