Magento不支持在前台禁止Magento方法但在后台保留。你也许可以做些调整配置来达到效果，但那不是100%正确的。虽然Magento支持“global/website/store”设置，在全球和网站级别，运输方法被打开或者关闭。在商店级别，你可以简单的编辑运输方式的title和其它东西，但你不能打开/关闭运输方式。

现在，想像下你Magento系统里只有一个网站，如果你在后台“Sales > Orders”点击“Create New Order”按钮。下面你将看到“please select a customer”来选择你想要创建订单的客户。但当你的Magento系统中有两个或更多网站时，你在后台“Sales > Orders”点击“Create New Order”按钮，下一个出来的就是“please select a website” ，之后才会看到“please select a customer”。这意味着Magento使用默认的网站或者你选择的网站来创建用户订单。无论哪种方式，它都从网站读取配置和运输数据。这意味着这种设置没办法在后台只显示某某运输方式……

我们如何绕过这点？简单，只需要重写Mage_Shipping_Model_Config和Mage_Sales_Model_Quote_Address。注意，这不一定是最好或者最优的方法，但却是一个可行的方法。

app/code/local/Mycompany/Myextension/Model/Adminhtml/System/Config/Source/Shipping/Methods.php

<?php
 
class Mycompany_Myextension_Model_Adminhtml_System_Config_Source_Shipping_Methods 
{
    protected $_options;
 
    public function toOptionArray()
    {
        $carriers = Mage::getSingleton('shipping/config')->getAllCarriers();
 
        $carriersActive = Mage::getSingleton('shipping/config')->getActiveCarriers();
        $carriersActive = array_keys($carriersActive);
 
        if (!$this->_options) {
            foreach ($carriers as $carrier) {
                $carrierCode = $carrier->getId();
                $carrierTitle = Mage::getStoreConfig('carriers/'.$carrierCode.'/title', Mage::app()->getStore()->getId());
                $carrierTitle = trim($carrierTitle);
 
                if (empty($carrierTitle)) {
                    continue;
                }
 
                if (in_array($carrierCode, $carriersActive)) {
                    $carrierTitle = sprintf('%s (currently active)', $carrierTitle);
                } else {
                    $carrierTitle = sprintf('%s (currently inactive)', $carrierTitle);
                }
 
                $this->_options[] = array('value'=>$carrierCode, 'label'=>$carrierTitle);
            }
        }
 
        $options = $this->_options;
 
        array_unshift($options, array('value'=>'', 'label'=> ''));
 
        return $options;
    }
}

这个文件被systemxml的“source_model”定义调用

<fields>
    <frontend_hidden_methods>
        <label>Hide Shipping Methods on Frontend</label>
        <comment></comment>
        <frontend_type>multiselect</frontend_type>
        <source_model>mycompany_myextension/adminhtml_system_config_source_shipping_methods</source_model>
        <sort_order>2</sort_order>
        <show_in_default>1</show_in_default>
        <show_in_website>1</show_in_website>
        <show_in_store>1</show_in_store>
    </frontend_hidden_methods>
</fields>

注意！上面的system.xml只是部分的，只用于实际字段的配置定义。

app/code/local/Mycompany/Myextension/Helper/Data.php

<?php
 
class Mycompany_Myextension_Helper_Data extends Mage_Core_Helper_Abstract

    const CONFIG_PATH_HIDE_FRONTEND_SHIPPING_METHODS = 'some-path-to-system-xml-field';
 
    public function getHiddenFrontendShippingMethods()
    {
        $methods = Mage::getStoreConfig(self::CONFIG_PATH_HIDE_FRONTEND_SHIPPING_METHODS);
        $methods = explode(',', $methods);
 
        return $methods;
    }
}

app/code/local/Mycompany/Myextension/Model/Shipping/Config.php

<?php

{
    public function getActiveCarriers($store = null)
    {
        $carriers = parent::getActiveCarriers($store);
 
        if (Mage::getDesign()->getArea() === Mage_Core_Model_App_Area::AREA_FRONTEND) {
 
            $carriersCodes = array_keys($carriers);
            $hiddenShippingMethods = Mage::helper('mycompany_myextension')->getHiddenFrontendShippingMethods();
 
            foreach ($carriersCodes as $carriersCode) {
                if (in_array($carriersCode, $hiddenShippingMethods)) {
                    unset($carriers[$carriersCode]);
                }
            }            
        }
 
        return $carriers;
    }
}

app/code/local/Mycompany/Myextension/Model/Sales/Quote/Address.php

<?php
 
class Mycompany_Myextension_Model_Sales_Quote_Address extends Mage_Sales_Model_Quote_Address
{
    public function getShippingRatesCollection()
    {
        parent::getShippingRatesCollection();
 
        $hiddenFrontendShippingMethods = Mage::helper('mycompany_myextension')->getHiddenFrontendShippingMethods();
 
        $removeRates = array();
 
        foreach ($this->_rates as $key => $rate) {
            if (in_array($rate->getCarrier(), $hiddenFrontendShippingMethods)) {
                $removeRates[] = $key;
            }   
        }
 
        foreach ($removeRates as $key) {
            $this->_rates->removeItemByKey($key);
        }
 
        return $this->_rates;
    }
}

基本上就是这样了。现在你的后台里有了多选框来选择特定的方法在前台隐藏后台保留。记住，运输方式必须是开启的，不要和启用/禁止“hide on frontend”相混淆。
