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_viewablebool -
Whether the post type is "viewable" (strict type).
-
$post_typeWP_Post_Type -
Post type object.
