pre_transient_{$transient}

Summery Summery

Filters the value of an existing transient.

apply_filters( "pre_transient_{$transient}", mixed $pre_transient, string $transient )

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

Passing a truthy value to the filter will effectively short-circuit retrieval of the transient, returning the passed value instead.

$pre_transient: 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 the returned value.
$transient: Transient name.
