| wp-includes/post.php | apply_filters | 2273 | /** * Filters whether a post type is considered "viewable". * * The returned filtered value must be a boolean type to ensure * `is_post_type_viewable()` only returns a boolean. This strictness * is by design to maintain backwards-compatibility and guard against * potential type errors in PHP 8.1+. Non-boolean values (even falsey * and truthy values) will result in the function returning false. * * @since 5.9.0 * * @param bool $is_viewable Whether the post type is "viewable" (strict type). * @param WP_Post_Type $post_type Post type object. */ |
