pre_site_transient_(transient) хук-фильтр . WP 2.9.0

Filters the value of an existing site transient before it is retrieved.

The dynamic portion of the hook name, $transient, refers to the transient name.

Returning a truthy value from the filter will effectively short-circuit retrieval and return the passed value instead.
