Cache Implementation In View or Controller
$cache = CFactory::getCache('Core'); // Random is to handle shuffle matter, // cache 3 different set of data. $intRandom = rand(COMMUNITY_CACHE_RANDOM_MIN, COMMUNITY_CACHE_RANDOM_MAX); // Cache does not exist, implement the cache data. if (!($data = $cache->load('frontpage_getLatestVideos_' . $intRandom))){ $data = // generate data $cache->save($data, NULL, array(COMMUNITY_CACHE_TAG_VIDEOS)); }
Cache Implementation / Removal In Model Class
To implement cache in model class, add the following code in the constructor:
// addMethod(methodName, [ACTION_SAVE, ACTION_REMOVE], [COMMUNITY_CACHE_TAG_ALL, array(TAG)]) $oCache = CCache::inject($this); $oCache->addMethod('getAllPhotos', CCache::ACTION_SAVE, array(COMMUNITY_CACHE_TAG_PHOTOS));
To remove cache in model class, add following code in models's constructor:
$oCache = CCache::inject($this); $oCache->addMethod('deleteActivity', CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_ACTIVITIES)); $oCache->addMethod('removeActivity', CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_ACTIVITIES));
Cache Remove In Table Class
Extend CTableCache (table/cache.php) in the table class:
class CTablePhoto extends CTableCache
Add the following code in the constructor:
// Get cache object. $oCache = CCache::inject($this); // Remove video cache on every delete & store $oCache->addMethod(CCache::METHOD_DEL, CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_VIDEOS)); $oCache->addMethod(CCache::METHOD_STORE, CCache::ACTION_REMOVE, array(COMMUNITY_CACHE_TAG_VIDEOS)); // Only CCache::METHOD_DEL, CCache::METHOD_SAVE, CCache::METHOD_STORE will handle by // the cache object,other methods need to be done manually by the class itself.
Cache Remove in User Plugin
Cache will be removed automatically when the following functions are triggered:
onAfterStoreUser()
onAfterDeleteUser()
