I'm new with Zend Framework. I'm using Zend cache, I pretty much copied code from the documentation, here is my code:
$frontendOptions = array(
'lifetime' => 3600, // cache lifetime of 1 hour
'automatic_serialization' => true
);
$backendOptions = array(
'cache_dir' => '../tmp/' // Directory where to put the cache files
);
// getting a Zend_Cache_Core object
$cache = Zend_Cache::factory('Core',
'File',
$frontendOptions,
$backendOptions);
// see if a cache already exists:
if( ($paginator = $cache->load('index' . $page)) === false ) {
$table = new self;
$query = $table->select()->setIntegrityCheck(false);
$query->from('feeds', array('feeds.blog_id', 'feeds.date_created', 'feeds.feed_id', 'feeds.post_content', 'feeds.post_link', 'feeds.post_title', 'feeds.post_thumb'));
$query->where('feeds.date_created <= NOW()');
$query->order('feeds.date_created DESC');
$paginator = new Zend_Paginator(new Zend_Paginator_Adapter_DbTableSelect($query));
$paginator->setItemCountPerPage(10);
$paginator->setCurrentPageNumber($page);
$cache->save($paginator, 'index' . $page);
}
return $paginator;
So after I go to the website that runs this query, I see the file being created, it's also a 19 or 20kb file, no matter which page im caching but the page is loading the same speed as before, also, if I update something in the database, I see the updated version, not the cache, I thought cache wouldnt show any updates for the lifetime of the cache. Any suggestions? Thanks
The paginator itself isn't the object you like to cache - you have to cache the results from db which will be done inside the paginator.
To do that there is a method to attach your cache object to the paginator
Zend_Paginator::setCache($cache);
$paginator->setCacheEnabled(true);
and the paginator will handle caching for you.
