我有一个功能，当没有访问权限的用户尝试查看单个帖子时，我会使用它显示登录通知。该功能还可以在存档、小部件等上公开显示帖子摘录，但仅在查看完整帖子时显示登录通知，即。is_singular

这基本上允许没有访问权限的用户在存档页面上查看帖子的片段，但当他们单击&；尝试查看完整帖子，系统会提示他们登录或注册。

我遇到的问题是，当使用相关帖子小部件时，会在不应该的时候显示登录通知。我很确定这与我如何在函数中定义post变量有关，这导致它无法区分小部件中显示为摘录的帖子与完整的单个帖子。寻找一些见解。

add_filter(\'mm_bypass_content_protection\', \'customContentProtection\');
