author_can()

author_can() — Returns whether the author of the supplied post has the specified capability. 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 );

Inputs: $post (int|WP_Post): Post ID or post object. $capability (string): Capability name.

Returns bool: Whether the post author has the given capability.
