WordPress 管理员：如何根据用户的角色显示现有的管理员子菜单

WordPress admin: How can I display existing admin sub-menu based on user's role

我需要根据特定用户角色显示管理菜单的现有子菜单项。角色是 general-travel-editor.

实际的菜单布局是这样的

Travel Settings
- General settings
- Advanced Settings

上述用户角色应该只能访问"常规设置"子菜单。所以我想为这种类型的用户显示菜单：

Travel Settings
- General settings

我尝试了 add_menu_page( 'Travel Settings', 'Travel Settings', 'general-travel-editor', 'general-travel-editor');，但我没有添加此页面 URL 的选项。

我正在使用 VIP 插件。
我需要在今晚之前交付，但卡住了！

请有人告诉我如何做到这一点。

更新

functions.php中定义的用户角色和能力

travel-option 是自定义帖子类型，因此我可以在 caps 数组中使用它。使用上述用户角色登录时，我可以看到 CPT 菜单很好地出现，但我如何添加此设置菜单？对于发布这么长的代码，我深表歉意！

我会在这里为面临相同情况的任何人留下另一个答案。

对我来说，我正在创建一个插件，并希望给它一个不同于(管理员)的角色

我搜索了已经存在的 wp 角色并选择了"作者"角色。此链接中提到了角色

这是我添加菜单的方法 =>

add_menu_page( 'Page Title', 'Menu title', 'upload_files', 'url slug', 'function name to be executed', $logo , 1 );

因此，您只需将 \\'upload_files\\' 替换为与所选角色匹配的任何其他功能。

add_submenu_page 函数 - 您应该用于"高级设置"的定义如下：

add_submenu_page( string $parent_slug, string $page_title, string
$menu_title, string $capability, string $menu_slug, callable $function
= '' );

如您所见，您可以定义一个特定的 $capability 来显示您的菜单或子菜单页面。

你可以使用一个只有管理员可以使用的能力，比如 manage_options，或者你甚至可以定义一个特殊的能力，像这样：

1 2	$role = get_role( 'administrator' ); $role->add_cap( 'edit_advanced_travel_settings' );

https://codex.wordpress.org/Function_Reference/add_cap

如果您操作正确，高级页面应该只对您授予此功能的用户可见。

注意：在自定义管理页面回调中 - 出于安全原因 - 您还应该检查当前用户是否具有所需的功能。
