1.页面

\app\design\adminhtml\default\default\template\report\grid\container.phtml

 <div>
        <form action="<?php echo $this->getUrl('*/report_sales/export') ?>" method="get">
            <?php echo $this->getBlockHtml('formkey')?>
        开始日期:<input type="date" name="start_date" placeholder="2016-03-01" required="required"/>
        结束日期:<input type="date" name="end_date" placeholder="2016-03-04" required="required"/>
            <button type="submit">导出</button>
        </form>
    </div>

2.控制器里
