pre_site_transient_(transient) filter-hookWP 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.

Usage

add_filter( 'pre_site_transient_(transient)', 'wp_kama_pre_site_transient_filter', 10, 2 );
