current_user_can_for_site() │ WP 6.7.0

Returns whether the current user has the specified capability for a given site.

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 edit_user are capabilities used by the map_meta_cap() 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 );

No Hooks.

Return

true|false. Whether the user has the given capability.

$site_id(int) (required)
