is_post_type_viewable WordPress Filter Hook
The is_post_type_viewable WordPress hook allows custom post types to be viewed by the public. This hook is useful for custom post types that need to be visible to the public, but not necessarily editable by them. By default, custom post types are not viewable by the public.
apply_filters( 'is_post_type_viewable', bool $is_viewable , WP_Post_Type $post_type ) #
Filters whether a post type is considered “viewable”.
Description
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.
Parameters
- $is_viewable
(bool)Whether the post type is "viewable" (strict type).
- $post_type
(WP_Post_Type)Post type object.
