## Code

```php
// Post type, its capability names, and the roles that manage it.
$wpide_cpt_caps = array(
    'post_type' => 'event',
    'singular'  => 'event',
    'plural'    => 'events',
    'roles'     => array( 'administrator', 'editor', 'author' ),
);

add_filter( 'register_post_type_args', function ( $args, $post_type ) use ( $wpide_cpt_caps ) {
    if ( $wpide_cpt_caps['post_type'] === $post_type ) {
        $args['capability_type'] = array( $wpide_cpt_caps['singular'], $wpide_cpt_caps['plural'] );
        $args['map_meta_cap']    = true;
    }

    return $args;
}, 10, 2 );

add_filter( 'user_has_cap', function ( $allcaps, $caps, $args, $user ) use ( $wpide_cpt_caps ) {
    if ( ! $user instanceof WP_User || ! array_intersect( (array) $user->roles, $wpide_cpt_caps['roles'] ) ) {
        return $allcaps;
    }

    $object = get_post_type_object( $wpide_cpt_caps['post_type'] );

    if ( ! $object ) {
        return $allcaps;
    }

    // Grant every primitive capability of this post type (edit_events, publish_events, ...).
    foreach ( (array) $object->cap as $meta => $primitive ) {
        if ( ! in_array( $meta, array( 'edit_post', 'read_post', 'delete_post' ), true ) ) {
            $allcaps[ $primitive ] = true;
        }
    }

    return $allcaps;
}, 10, 4 );
```

## Notes

Administrators keep full access. The permissions are granted while the snippet runs, so nothing is written to the database.
