author_can( int|WP_Post $post, string $capability, mixed $args )
Returns whether the author of the supplied post has the specified capability.
Description 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 Parameters
- $post
-
(int|WP_Post) (Required) Post ID or post object.
- $capability
-
(string) (Required) Capability name.
- $args
-
(mixed) (Optional) further parameters, typically starting with an object ID.
Return Return
(bool) Whether the post author has the given capability.
