current_user_can_for_blog( int $blog_id, string $capability, mixed $args )

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.

Example usage:

current_user_can_for_blog( $blog_id, 'edit_posts' );
current_user_can_for_blog( $blog_id, 'edit_post', $post->ID );
current_user_can_for_blog( $blog_id, 'edit_post_meta', $post->ID, $meta_key );

Parameters

$blog_id

(Required) Site ID.

$capability

(Required) Capability name.

$args

(Optional) further parameters, typically starting with an object ID.

Return

(bool) Whether the user has the given capability.
