根据您的最后评论，有几点需要考虑：
- 以可视方式隐藏任何编辑/删除等提示。
- 删除所有默认链接样式。
- 防止直接访问。
- 阻止数据库更新。
您可以通过pre_post_update 操作钩子拦截帖子编辑，该钩子在现有帖子在数据库中更新之前立即触发。
我们可以使用post_row_actions 过滤帖子列表中的行操作链接数组，以防止编辑操作。
最后我们使用admin_head-{$hook_suffix}钩子来移除任何视觉风格并防止通过URL直接访问。
所有内容都包含在一个类中以使其更容易。

顺便说一句，删除帖子被视为编辑。
您不需要 prevent_default_theme_deletion() 函数。
您可能很想使用 edit_post 操作挂钩，但这不起作用，因为：
edit_post：在现有帖子更新后触发。
“once”语句是我们需要使用pre_post_update 的原因。
pre_post_update：在数据库中更新现有帖子之前立即触发。
