调试时 getOrder() 不返回 Mage_Sales_Model_Order

Question

我尝试var_dump($order)，但它给了我：

object(Varien_Object)#290 (7) { ["_data":protected]=> array(0) { } ["_hasDataChanges":protected]=> bool(false) ["_origData":protected]=> NULL ["_idFieldName":protected]=> NULL ["_isDeleted":protected]=> bool(false) ["_oldFieldsMap":protected]=> array(0) { } ["_syncFieldsMap":protected]=> array(0) { } }

我的class PaketId_Shipping_Block_Adminhtml_Sales_Order_Shipment_View_Shipping extends Mage_Sales_Block_Order_Shipment {

protected $order;

public function getOrder() {
    if (is_null($this->order)) {
        if (Mage::registry('current_order')) {
            $order = Mage::registry('current_order');
        }
        elseif (Mage::registry('order')) {
            $order = Mage::registry('order');
        }
        else {
            $order = new Varien_Object();
        }
        $this->order = $order;
    }
    return $this->order;
}

我的 phtml 文件：

<?php echo $this->getChildHtml('PaketId_Shipping');?>
<h1>Test custom block</h1>
<?php $order = $this->getOrder()?>
<?php var_dump($order);?>
<?php $shippings = Mage::getModel('paketid_shipping/result')->getCollection()->addOrderFilter($order) ?>
<?php echo "<pre>";?>
<?php var_dump($shippings);?>
<?php echo "</pre>" ;?>

我在 phtml 文件中的变量$order 不知何故没有调用块文件中的$order，或者我对此有误解？因为，当我尝试在其他 phtml 中 var_dump($order) 时，它会返回 object(Mage_Sales_Model_Order)#276...

我尝试将$this-getOrder() 更改为Mage::registry('current_order')，但它给了我NULL。我做错了什么？

我的收藏：

class PaketId_Shipping_Model_Resource_Result_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract
{

protected function _construct()
{
    parent::_construct();
    $this->_init('paketid_shipping/result');
}
public function addOrderFilter($order)
{
    if ($order instanceof Mage_Sales_Model_Order) {
        $order = (int) $order->getId();
    }
    if (!is_array($order)) {
        $order = array($order);
    }

    $this->getSelect()->where("main_table.order_id IN (?)", $order);

    return $this;
}
protected function _toOptionArray($valueField='entity_id', $labelField='booking_code', $additional=array())
{
    return parent::_toOptionArray($valueField, $labelField, $additional);
}
protected function _toOptionHash($valueField='entity_id', $labelField='booking_code')
{
    return parent::_toOptionHash($valueField, $labelField);
}
public function getSelectCountSql()
{
    $countSelect = parent::getSelectCountSql();
    $countSelect->reset(Zend_Db_Select::GROUP);
    return $countSelect;
}

我的资源：

class PaketId_Shipping_Model_Resource_Result extends Mage_Core_Model_Resource_Db_Abstract
public function _construct()
{
    $this->_init('paketid_shipping/result', 'entity_id');
}

我的结果：

class PaketId_Shipping_Model_Result extends Mage_Core_Model_Abstract
const ENTITY    = 'paketid_shipping_result';
const CACHE_TAG = 'paketid_shipping_result';
protected $_eventPrefix = 'paketid_shipping_result';
protected $_eventObject = 'paketid_shipping_result';
public function _construct()
{
    parent::_construct();
    $this->_init('paketid_shipping/result');
}

管理布局 xml：

<layout version="1.0">
<adminhtml_sales_order_shipment_new>
    <reference name="content">
        <block type="paketid_shipping/adminhtml_sales_order_shipment_view_shipping" name="paketid_shipping.order.view.shipping.block" template="paketid/shipping.phtml"/>
    </reference>
</adminhtml_sales_order_shipment_new>

请从 Mage_Sales_Block_Order_Shipment 或 Mage_Sales_Block_Order_View 调用扩展您的模块类并检查它希望这有帮助。
