Magento Caching

Hur cachar du anpassade data till Magento

const CACHE_TAG_NAMESPACE_MODULE = "YOUR_MODULES_CACHE_TAGS";
$cacheGroup = 'namespace_module';
$useCache = Mage::app()->useCache($cacheGroup);
if (true === $useCache) {    
    $cacheId = 'unique_name';
    if ($cacheContent = Mage::app()->loadCache($cacheId)) {
        $html = $cacheContent;
        return $html;
    } else {
        try {
            $cacheContent = $html;
            $tags = array(model::CACHE_TAG_NAMESPACE_MODULE);
            $lifetime = Mage::getStoreConfig('core/cache/lifetime');
            Mage::app()->saveCache($cacheContent, $cacheId, $tags, $lifetime);
        } catch (Exception $e) {
            // Exception = no caching
            Mage::logException($e);
        }
        return $html;
   }
}
// Default:
return $html;

Rengör cache efter cache-ID

Mage::app()->removeCache($cacheId); 

Spola alla Magento-cacheposter

Mage::app()->cleanCache()

eller:

Mage::app()->getCacheInstance()->flush();

Använd Redis som cache-backend

Redis konfiguration:

1. Installera redis (2.4+ krävs)
2. Installera phpredis
3. Installera Magento-förlängningen Cm_Cache_Backend_Redis (endast för Magento 1.7 och senare)
4. Redigera din app/etc/local.xml :

<global>
  ...
  <cache>
    <backend>Cm_Cache_Backend_Redis</backend>
    <backend_options>
      <server>127.0.0.1</server> <!-- or absolute path to unix socket -->
      <port>6379</port>
      <persistent></persistent>
      <database>0</database>
      <password></password>
      <force_standalone>0</force_standalone>
      <connect_retries>1</connect_retries>
      <automatic_cleaning_factor>0</automatic_cleaning_factor>
      <compress_data>1</compress_data>
      <compress_tags>1</compress_tags>
      <compress_threshold>20480</compress_threshold>
      <compression_lib>gzip</compression_lib> <!-- Supports gzip, lzf and snappy -->
    </backend_options>
  </cache>
  ... 
</global>
