我有一个叫“作者”的CPT。在一个小时的搜索之后，我发现为什么这个CPT（由模板“single author.php”管理）有404个访问单页，我意识到有些人确实有用：那些slug中没有连字符的人！

所以对于作家伏尔泰，我的网站。com/作者/伏尔泰/作品。然而，对于“亚历山大大仲马”，我的网站。com/author/alexandre-dumas/给出了一个404。如果我把这个弹头从“亚历山大大仲马”改为“亚历山大大仲马”，不加连字符，它就行了。

我需要在我的作者slug中使用连字符（否则我需要让我的客户手动编辑她创建或创建的每个作者的slug），如何做到这一点？

我的CPT声明：

    $labels = array(
        \'name\'               => _x( \'Book Authors\', \'post type general name\' ),
