I have a feature on my store that allows me to auto-generate a product quote, after the quote's attributes, prices, and shipping rules, I create a new product on the fly.
I don't want these products to show on my catalogue or searches, so I've been trying to figure out how to update the "Catalog Visibility" to Hidden.
At first I was trying:
update_post_meta( $prod_ID, '_visibility', 'hidden' );
The meta is added, however, looking into it I found out that WooCommerce changed the way it specifies if a product is visible or hidden:: below is from WooCommerce
Product visibility is taxonomy based instead of meta based 3.0.0 introduces a new product visibility taxonomy; catalogue, search, hidden, featured, out of stock are terms. These are set to upgrade and help filter products in the catalogue during frontend queries.
My issue is; how can I modify a taxonomy via PHP.
我的商店有一项功能，允许我在报价属性，价格后自动生成产品报价 和运输规则，我即时创建一个新产品。
我不希望这些产品显示在我的目录或搜索上，所以我一直试图弄清楚如何 将“目录可见性”更新为隐藏。
首先我尝试：
update_post_meta（$ prod_ID，'_ visible“， 'hidden'）;
添加了元数据，然而，在调查中我发现WooCommerce改变了它指定产品是否可见或隐藏的方式： ：以下是来自WooCommerce
产品可见性是基于分类而非基于元的
3.0.0引入了新的产品可见性分类; 目录，搜索，隐藏，特色，缺货是条款。 这些设置为在前端查询期间升级并帮助过滤目录中的产品。
我的问题是; 如何通过PHP修改分类法。
it should be something like this:
微信扫一扫$terms = array( 'exclude-from-search', 'exclude-from-catalog' ); // for hidden..
wp_set_post_terms( $prod_ID, $terms, 'product_visibility', false );
