您可以在插件文件夹中创建一个新文件夹，称为“自定义分类法”。创建名为“custom taxonomy”的文件。并将下面的代码粘贴到其中。单词“Image”和“Images”应替换为当前主题的自定义分类法的名称。

别忘了激活插件。此外，您可能需要更改“public”和“has\\u archive”等内容的真/假值。

您可以使用unregister_post_type(\'slug\') - 其中，“slug”是CPT，如“投资组合”或“账簿”或您的特定CPT，然后重新注册CPT。我建议您在自己的自定义插件中执行此操作，以便您可以自由更改主题。

因此，如果您的CPT是“公文包”，您可以在/wp-content/plugins/wpse_360145_create_cpt/create-cpt.php:

<?php
/* Plugin Name: Create CPT */

// Run everything when the plugin is activated
register_activation_hook(__FILE__, \'wpse_360145_activation\');
function wpse_360145_activation() {
    // First, unregister the post type
    // (be sure to set this to *your* CPT)
    unregister_post_type(\'portfolio\');
    // Next, re-register it from scratch
    // (You may have to play around with the settings)
    register_post_type(\'portfolio\',
        array(
            // Plural, human-readable label for menu
            \'label\' => \'Portfolio Pieces\',
            // Show in REST API must be true for the Block Editor
            \'show_in_rest\' => true,
            // Enable Title, Editor, and Excerpt
            \'supports\' => array(\'title\', \'editor\', \'excerpt\'),
            // has_archive will create http://example.com/portfolio
            // much like a Post Category archive
            \'has_archive\' => \'portfolio\'
        )
    );
}
?>

使用这种方法，您只需激活插件来尝试设置，如果需要调整，请停用、进行更改并重新激活，然后unregister_post_type() 呼叫将确保旧的尝试被完全清除。

在旧主题中，将所有将post“type register\\u post\\u type（）”等注册到函数中的代码复制到函数中。新主题的php。
