/** | |
* Maps a capability to the primitive capabilities required of the given user to | |
* satisfy the capability being checked. | |
* | |
* This function also accepts an ID of an object to map against if the capability is a meta capability. Meta | |
* capabilities such as `edit_post` and `edit_user` are capabilities used by this function to map to primitive | |
* capabilities that a user or role requires, such as `edit_posts` and `edit_others_posts`. | |
* | |
* Example usage: | |
* | |
* map_meta_cap( 'edit_posts', $user->ID ); | |
* map_meta_cap( 'edit_post', $user->ID, $post->ID ); | |
* map_meta_cap( 'edit_post_meta', $user->ID, $post->ID, $meta_key ); | |
* | |
* This function does not check whether the user has the required capabilities, | |
* it just returns what the required capabilities are. | |
* | |
* @since 2.0.0 | |
* @since 4.9.6 Added the `export_others_personal_data`, `erase_others_personal_data`, | |
* and `manage_privacy_options` capabilities. | |
* @since 5.1.0 Added the `update_php` capability. | |
* @since 5.2.0 Added the `resume_plugin` and `resume_theme` capabilities. | |
* @since 5.3.0 Formalized the existing and already documented `...$args` parameter | |
* by adding it to the function signature. | |
* @since 5.7.0 Added the `create_app_password`, `list_app_passwords`, `read_app_password`, | |
* `edit_app_password`, `delete_app_passwords`, `delete_app_password`, | |
* and `update_https` capabilities. | |
* | |
* @global array $post_type_meta_caps Used to get post type meta capabilities. | |
* | |
* @param string $cap Capability being checked. | |
* @param int $user_id User ID. | |
* @param mixed ...$args Optional further parameters, typically starting with an object ID. | |
* @return string[] Primitive capabilities required of the user. | |
