Magento 1 – How to Disable Cache for Particular Section or Block

blockscachece-1.6.2.0magento-1

I have developed a top bar cart functionality for store front that displays latest three products added to the cart this works great when cache is disabled but when i enable the cache it showing weird subtotal in top cart and weird products in cart.

This make me sad :'(

I know this is happening because of cache. Is there anything that I can disable the cache for this section only? I have tried disabling the block html cache and check now this was working great but I found the category flat is having unspecified issues when block HTML is disabled.

You can try

    <reference name="needed block">
        <action method="setCacheLifetime"><s>null</s></action>
    </reference>

    <reference name="needed block">
        <action method="setCacheLifetime" />
    </reference>

to set it to null.

But probably it is better to use ajax.

There is a good article about null or 0 meaning ~~http://blog.kyp.fr/make-a-clean-sweep-of-commons-magento-cache_lifetime-workarounds-usage-in-cache-block-policy/~~ ^{(link is broken)}

To disable Block Html Cache you should set cacheLifeTime to null. You can see more details in Mage_Core_Block_Abstract::_loadCache()

protected function _loadCache()
{
    if (is_null($this->getCacheLifetime()) || !$this->_getApp()->useCache(self::CACHE_GROUP)) {
        return false;
    }
    ...
}

You may be using an alternative cache backend, in which case, using the Flush Cache Storage button should be sufficient to empty the cache contents.

If you are using a cache backend that doesn't support tagging (eg. Memcache), then conditionally flushing caches isn't going to work (unless you are using two-level caching).

You can verify the cache backend by looking in your ./app/etc/local.xml file between the <cache/> tags.
