Is it mandatory to create single post page for each of the custom post types?不，不是全部。如果添加“public\\u queryable”=>false；系统不会为您的CPT创建单页条目。（确保在此更改后刷新永久链接）

If not, then what about the ‘href’ attribute value(where we write this code the_permalink()) of the anchor tag ()? Should I keep it dead like href=”#”?当public\\u queryable arg设置为false时，这将只加载到主页

Is it mandatory to design Section Page, Portfolio Page etc. which are created by custom page templates? 不，不是。事实上，如果您将“has\\u archive”=>设置为false；这些页面也不会加载，如果有人试图转到那些存档页面“www.example.com/your\\cpt”，它也会加载到主页。（进行此更改后，请记住刷新永久链接）

Is it mandatory to keep ‘has_archive’ => true in the custom post register? 否。请参阅以上问题的答案。

或者，您可以将其添加到插件中。但此调用只应作为初始化的一部分进行，因为它确实使用了大量资源。您可以这样做：

function my_rewrite_flush() {
    // First, we "add" the custom post type via the above written function.
    // Note: "add" is written with quotes, as CPTs don\'t get added to the DB,
    // They are only referenced in the post_type column with a post entry, 
    // when you add a post of this CPT.
    my_cpt_init();

    // ATTENTION: This is *only* done during plugin activation hook in this example!
    // You should *NEVER EVER* do this on every page load!!
    flush_rewrite_rules();
}

register_activation_hook( __FILE__, \'my_rewrite_flush\' );
