pre_transient_(transient) filter-hook . WP 2.8.0
Filters the value of an existing 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_transient_(transient)', 'filter_function_name_3817', 10, 2 ); function filter_function_name_3817( $pre_transient, $transient ){ // filter... return $pre_transient; }
- $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.
