user_can_for_site()

user_can_for_site() — Returns whether a particular 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.

Example usage: user_can_for_site( $user->ID, $site_id, ‘edit_posts’ ); user_can_for_site( $user->ID, $site_id, ‘edit_post’, $post->ID ); user_can_for_site( $user->ID, $site_id, ‘edit_post_meta’, $post->ID, $meta_key );

Inputs: $user (int|WP_User): User ID or object. $site_id (int): Site ID. $capability (string): Capability name.

Returns bool: Whether the user has the given capability.
