add comment field in checkout page

1.在order view或者billing页面加入HTML原件

<li>
    <label for="orderComment"><?php echo $this->__('Comments'); ?></label>
    <textarea name="orderComment" id="orderComment" rows="3" cols="60"></textarea>
</li>

 

2.在自己的module中添加事件配置

<frontend>
    <events>
      <checkout_type_onepage_save_order>
        <observers>
          <checkout_type_onepage_save_order_handler>
            <type>singleton</type>
            <class>mysales/observer</class>
            <method>saveOrder</method>
          </checkout_type_onepage_save_order_handler>
        </observers>
      </checkout_type_onepage_save_order>
    </events>
  </frontend>

 3.触发事件的方法

   public function saveOrder($evt) {	
      $_order   = $evt->getOrder();
      $_request = Mage::app()->getRequest(); 
      $_comments = strip_tags($_request->getParam('orderComment'));
      if(!empty($_comments)){
        $_comments = 'Additional Order Comments: ' . $_comments;
        $_order->setCustomerNote($_comments);
      }
      return $this;     
    }

 

这样就可以在下单的时候写下第一条评论了
