Recently I had performance issues when importing several ten tausend products. The problem was, that I always used the “normal” product entity model to load attribute values. The following snippet shows, how to load product attributes directly instead. Therefore I use the product resource singleton. <?php $iProductId = $aChange[‘pid’]; $oItem = new Varien_Object; /** * […]
This Magento shell script sorts the values of a given attribute after the order of values in a given CSV file (sets option value position). <?php /** * * Magento * * NOTICE OF LICENSE * * This source file is subject to the Open Software License (OSL 3.0) * It is available through the world-wide-web at […]

Therefore the given store specific value […]
This is how to get product EAVÂ attribute ID without querying the database directly: <?php $iAttributeID = Mage::getSingleton(‘eav/config’)->getAttribute(Mage_Catalog_Model_Product::ENTITY, self::TARGET_ATTRIBUTE)->getId()
The following snippet shows, how to create database tables in a setup script. It uses no direct queries against the database but the an object oriented way Magento does such things. (This snipped assumes  that your resource setup model is derived from Mage_Core_Model_Resource_Setup) <?php /** * * Magento * * NOTICE OF LICENSE * * This […]
Sometimes Magento indexes hang up unexpectedly. They are shown as running in Magento backend but looking at the process status (@see https://www.ask-sheldon.com/list-processes-after-cpu-usage/), you recognize that the respective process doesn’t do anything. Other common problems are, that there are payment transactions failures when price index is running (catalog_product_price @see http://magento.stackexchange.com/questions/260/price-re-index-causes-db-deadlocks-during-checkout) or that the search doesn’t work properly, […]
