修改Magento默认Export Customers功能(2)_magento教程_php教程

　　　　我现在要给导出的.CSV文件添加Subscribe项，需要修改传给_prepareDownloadResponse()方法的第2个参数$model->export()：

　　　　具体步骤：首先修改$collection，让$collection包含customers的subscriber数据

1 $collection->getSelect()->joinLeft(

2 array('ns' => 'newsletter_subscriber'),

3 'ns.customer_id = e.entity_id',

4 'ns.subscriber_status'

5 );

　　　　然后在$row数组中添加Subscriber数据：
