author_can( int|WP_Post $post, string $capability, mixed $args )

Returns whether the author of the supplied post has the specified capability.


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:

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

Parameters

$post

(Required) Post ID or post object.

$capability

(Required) Capability name.

$args

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


Return

(bool) Whether the post author has the given capability.
