$cache->saveFor() method

Same as save() except with namespace

Namespace is useful to avoid cache name collisions. The ProcessWire core commonly uses cache namespace to bind cache values to the object class, which often make a good namespace.

Example

// save cache using manually specified namespace
$cache->save("my-namespace", "my-cache-name", $value);

// save cache using namespace of current object
$cache->save($this, "my-cache-name", $value); 

Usage

// basic usage
$bool = $cache->saveFor($ns, string $name, $data);

// usage with all arguments
$bool = $cache->saveFor($ns, string $name, $data, $expire = 86400);

Arguments

“To Drupal, or to ProcessWire? The million dollar choice. We decided to make an early switch to PW. And in retrospect, ProcessWire was probably the best decision we made. Thanks are due to ProcessWire and the amazing system and set of modules that are in place.” —Unni Krishnan, Founder of PigtailPundits
