WordPress 分类术语元不适用于导出和导入

Question

我已经为自定义帖子类型创建了一个分类元数据，它在保存、更新、编辑等时工作正常。但在使用 WordPress 导入器导入或导出时它不起作用。分类法元数据不会导入。

这是基于 Tutorial 的代码

<?php
if ( ! function_exists( 'register_cpt_houses' ) ) {
    function register_cpt_houses() {
        $labels = array(
            'name'              => __('houses', 'my_plugin'),

我做错了什么？

如果您需要导出 termmeta 表中的数据，请尝试使用此插件将 termmeta 数据导出到单独的 XML 文件中。

导出自定义帖子类型只会让您在分类 ID 和导出的帖子之间建立联系。要获取该分类法的元数据，请尝试使用此插件，它将为您提供一个 XML，其中包含该分类法的所有其他条目，您也可以导入它

您可以在工具 -> Wp Export Cats & Taxs

中找到此内容
