product attributes Archives - ACTIVO
This static method can copy attributes between products in Magento very fast and relatively secure. We are bypassing the main Magento architecture and accessing the Database directly, but notice we are using the Zend framework for the db query and we still use DB transactions. It accepts the source product ID (not SKU), destination product ID, the array of attribute codes (‘size’, ‘color’, ‘name’, etc.), and the attribute type (‘varchar’, ‘int’, etc.).
