current_user_can_for_site()
云策文档标注
概述
current_user_can_for_site() 函数用于检查当前用户是否在指定站点上拥有特定权限。它支持元权限（如 edit_post）的映射检查，并取代了已弃用的 current_user_can_for_blog() 函数。
关键要点
- 函数接受站点ID、权限名称和可选参数（如对象ID）作为输入，返回布尔值表示用户是否拥有该权限。
- 在Multisite环境中，函数会临时切换站点（使用 switch_to_blog() 和 restore_current_blog()）以执行权限检查。
- 适用于需要跨站点权限验证的场景，例如在编辑文章或用户时检查特定站点的权限。
代码示例
current_user_can_for_site( $site_id, 'edit_posts' );
current_user_can_for_site( $site_id, 'edit_post', $post->ID );
current_user_can_for_site( $site_id, 'edit_post_meta', $post->ID, $meta_key );
原文内容
Returns whether the current user has the specified capability for a given site.
Description
This function also accepts an ID of an object to check against if the capability is a meta capability. Meta capabilities such as edit_post and edit_user are capabilities used by the map_meta_cap() function to map to primitive capabilities that a user or role has, such as edit_posts and edit_others_posts.
This function replaces the current_user_can_for_blog() function.
Example usage:
current_user_can_for_site( $site_id, 'edit_posts' );
current_user_can_for_site( $site_id, 'edit_post', $post->ID );
current_user_can_for_site( $site_id, 'edit_post_meta', $post->ID, $meta_key );Parameters
$site_idintrequired-
Site ID.
$capabilitystringrequired-
Capability name.
$argsmixedoptional-
Optional further parameters, typically starting with an object ID.
