覆盖核心的Helper Data类

现在应用模块的config.xml里面配置

    <helpers>
            <mycustomer>
                <class>Bysoft_Mycustomer_Helper</class>
            </mycustomer>
            <customer>
            	<rewrite>
            		<data>Bysoft_Mycustomer_Helper_Data</data>
            	</rewrite>
            </customer>
    </helpers>

 

然后覆盖的时候这么写

class Bysoft_Mycustomer_Helper_Data extends Mage_Customer_Helper_Data
{
     public function getSalesOrderHistoryUrl() {
    	return $this->_getUrl('sales/order/history');
    }
}
