pre_transient_{$transient} WordPress Filter Hook
The pre_transient_{$transient} hook is fired before the value of a transient is read from the database. It is useful for modifying the value of a transient before it is used by the application.
apply_filters( "pre_transient_{$transient}", mixed $pre_transient , string $transient ) #
Filters the value of an existing transient before it is retrieved.
Description
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.
Parameters
- $pre_transient
(mixed)The default value to return if the transient does not exist. Any value other than false will short-circuit the retrieval of the transient, and return that value.
- $transient
(string)Transient name.
