Question

在WooCommerce中，我想知道如何通过php脚本和mysql更改woocommerce的产品属性。

这是我正在做的事情：我已经通过wordpress创建了属性，并且已经在产品上激活了主题：

我在wp_terms中创建了新名词。
我在wp_term_taxonomy的分类法中的pa_attribute表中创建了新记录。
我已分配了term_taxonomy_id表中的分类ID wp_term_relationships。

现在，为什么新条款不在产品中显示？如果我执行该步骤？我错了什么或我想念什么？

问题与我在wp_term_relationship中添加或删除的内容无关紧要，产品属性不变。

我认为问题在于某些wp缓存，如何在不使用Wordpress函数的情况下将其全部删除。附注：我使用该教程来编写脚本：https://www.webhat.in/article/woocommerce-tutorial/how-product-attribute-are-stored-in-database/ 我所有的代码：

    the slug is "$parola-$termine_aggiuntivo" if $termine_aggiuntivo
    is not empty

    $termine_aggiuntivo=trim($termine_aggiuntivo);
    if(strcasecmp($parola, "non-comunicato") == 0)
