最简单的方法是创建两种自定义帖子类型。一个是“新闻”，另一个是“新内容”。

例如，您可以在/wp-content/plugins/ 调用news-post-types.php. 以下代码将创建仅适用于此帖子类型的特殊权限：

<?php
/* Plugin Name: Post types and permissions for News and What\'s New
*/
// on init, create a custom post type called News
add_action(\'init\', \'wpse_create_post_types\');
function wpse_create_post_types() {
    // Capabilities: this is how you\'ll enable some users to edit, delete, etc.
    $capabilities = array(
        \'edit_post\'                 => \'edit_news\',
        \'read_post\'                 => \'read_news\',
        \'delete_post\'               => \'delete_news\',
        \'create_posts\'              => \'create_news\',
        \'delete_posts\'              => \'delete_news\',
        \'delete_others_posts\'       => \'delete_others_news\',
        \'delete_private_posts\'      => \'delete_private_news\',
        \'delete_published_posts\'    => \'delete_published_news\',
        \'edit_posts\'                => \'edit_news\',
        \'edit_others_posts\'         => \'edit_others_news\',
        \'edit_private_posts\'        => \'edit_private_news\',
        \'edit_published_posts\'      => \'edit_published_news\',
        \'publish_posts\'             => \'publish_news\',
        \'read_private_posts\'        => \'read_private_news\'
    );
    // Other CPT arguments
    $args = array(
        // Important: make sure to include the next 2 args for capabilities
        \'map_meta_cap\' => true,
        \'capabilities\' => $capabilities,
        // You can adjust the other args as needed
        \'public\' => true,
        \'has_archive\' => true,
        \'hierarchical\' => false,
        \'supports\' => array(\'title\', \'editor\', \'author\', \'page-attributes\')
    );
    // Actually create the post type
    register_post_type(\'news\', $args);
}

只要您指定has_archive 注册自定义帖子类型时，也会自动为每个帖子获取一个类似于类别的页面，而无需创建任何自定义模板。

确保激活插件，并访问设置>永久链接页面。您不需要在那里更改任何内容，但这将刷新您的重写规则，以便新URL正常运行。

现在，您有了一个具有自定义功能的自定义post类型。您至少还需要做一件事：创建一个具有这些权限的角色。现在，您的任何用户（甚至管理员）都没有访问权限，这是因为您刚刚创建了不会自动映射到任何用户的自定义功能。

在同一插件文件中：

// \'news_author\' is a slug, \'News Author\' is how you will see this role in wp-admin
add_role(\'news_author\', \'News Author\', array(
    // You may or may not want to give them all these capabilities.
    // For example you could let them publish but not delete.
    \'delete_news\' => true,
    \'create_news\' => true,
    \'delete_news\' => true,
    \'delete_others_news\' => true,
    \'delete_private_news\' => true,
    \'delete_published_news\' => true,
    \'edit_news\' => true,
    \'edit_others_news\' => true,
    \'edit_private_news\' => true,
    \'edit_published_news\' => true,
    \'publish_news\' => true,
    \'read_private_news\' => true,
    // If you want them to be able to upload files and read on the front end,
    // make sure to include the following 2 capabilities:
    \'read\' => true,
    \'upload_files\' => true
));

最后，你可能还想让管理员（也许像你一样）能够添加/编辑/删除这些自定义新闻帖子。如果是，请将以下内容添加到插件：

add_action(\'admin_init\', \'wpse_add_admin_caps\');
function wpse_add_admin_caps() {
    $role = get_role(\'administrator\');
    $role->add_cap(\'delete_news\');
    $role->add_cap(\'create_news\');
    $role->add_cap(\'delete_news\');
    $role->add_cap(\'delete_others_news\');
    $role->add_cap(\'delete_private_news\');
    $role->add_cap(\'delete_published_news\');
    $role->add_cap(\'edit_news\');
    $role->add_cap(\'edit_others_news\');
    $role->add_cap(\'edit_private_news\');
    $role->add_cap(\'edit_published_news\');
    $role->add_cap(\'publish_news\');
    $role->add_cap(\'read_private_news\');
}

您可以对“新增内容”部分执行相同的操作—创建第二个自定义帖子类型，然后为其添加角色，然后也可以选择将这些功能添加到管理员角色。
