One or more of the Cache Types are invalidated: Blocks HTML output

In Magento 1.5 displaying message to pop on every product save.

If you go to system -> Cache management -> (Invalid )option


Here is the solution  ....

Add this in your module config.xml:

<global>

<models>

<catalogrule>

    <rewrite>

        <rule>Yourpackage_Yourmodule_Model_Rule</rule>

    </rewrite>

</catalogrule>

</models>




Create file called Rule.php in YOUR module Model directory.

Add this code in newly created file:




class Yourpackage_Yourmodule_Model_Rule extends Mage_CatalogRule_Model_Rule

{

   /**

     * Apply all price rules to product

     *

     * @param int|Mage_Catalog_Model_Product $product

     * @return Mage_CatalogRule_Model_Rule

     */

    public function applyAllRulesToProduct($product)

    {

        $this->_getResource()->applyAllRulesForDateRange(NULL, NULL, $product);

        $this->_invalidateCache();

        //Notice this little line

    Mage::app()->getCacheInstance()->cleanType('block_html');

        $indexProcess = Mage::getSingleton('index/indexer')->getProcessByCode('catalog_product_price');

        if ($indexProcess) {

            $indexProcess->reindexAll();

        }

    }

}
