        </Jeweldroship_Checkoutcomments>
    </modules>
    <frontend>
     <events>
       <sales_order_save_after>
         <observers>
            <jeweldroship_checkoutcomments>
                <type>singleton</type>
                <class>jeweldroship_checkoutcomments/observer</class>
                <method>salesOrderSaveAfter</method>
            </jeweldroship_checkoutcomments>
         </observers>
       </sales_order_save_after>
     </events>
    </frontend>
</config>

My Observer.php

```
<?php 
class Jeweldroship_Checkoutcomments_Model_Observer
{ 
    public function salesOrderSaveAfter($observer) {
         $resource = Mage::getSingleton('core/resource');
         $writeConnection = $resource->getConnection('core_write');
         $sql = "insert into mg_order_log set order_id='1',created=".time();
         $writeConnection->query($sql);
         echo "Product has been imported successfully.";
    }
 }
