pre_transient_(transient) filter-hook . WP 2.8.0

Filters the value of an existing 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.

Usage

add_filter( 'pre_transient_(transient)', 'filter_function_name_873', 10, 2 );
function filter_function_name_873( $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 the returned value.

$transient(string)

Transient name.

Notes

• Since 4.4.0 The $transient parameter was added
