然后我创建了一个模型类
Then I created a model class
<?php
/**
* Our test CC module adapter
*/
class Companyname_Cashondelivery_Model_createorder extends Mage_Payment_Model_Method_Cc
{
/**
* unique internal payment method identifier
*
* @var string [a-z0-9_]
*/
protected $_code = 'newmodule';
/**
* Here are examples of flags that will determine functionality availability
* of this module to be used by frontend and backend.
*
* @see all flags and their defaults in Mage_Payment_Model_Method_Abstract
*
* It is possible to have a custom dynamic logic by overloading
* public function can* for each flag respectively
*/
/**
* Is this payment method a gateway (online auth/charge) ?
*/
protected $_isGateway = true;
/**
* Can authorize online?
*/
protected $_canAuthorize = true;
/**
* Can capture funds online?
*/
protected $_canCapture = false;
/**
* Can capture partial amounts online?
*/
protected $_canCapturePartial = false;
/**
* Can refund online?
*/
protected $_canRefund = false;
/**
* Can void transactions online?
*/
protected $_canVoid = true;
/**
* Can use this payment method in administration panel?
*/
protected $_canUseInternal = true;
/**
* Can show this payment method as an option on checkout payment page?
*/
protected $_canUseCheckout = true;
/**
* Is this payment method suitable for multi-shipping checkout?
*/
protected $_canUseForMultishipping = true;
/**
* Can save credit card information for future processing?
*/
protected $_canSaveCc = false;
/**
* Here you will need to implement authorize, capture and void public methods
*
* @see examples of transaction specific public methods such as
* authorize, capture and void in Mage_Paygate_Model_Authorizenet
*/
}
?>
我什至在app/local/Companyname/Cashondelivery/Helper/Data.php中创建了一个文件
I have even created a file in app/local/Companyname/Cashondelivery/Helper/Data.php
<?php
class Companyname_Cashondelivery_Helper_Data extends Mage_Core_Helper_Abstract
{
}
?>
但是当我打开配置">付款方式"
But I get an error when I open Configuration>Payment Methods
致命错误:在第516行的C:\ xampp \ htdocs \ magento \ app \ Mage.php中找不到类'Mage_Cashondelivery_Helper_Data'
Fatal error: Class 'Mage_Cashondelivery_Helper_Data' not found in C:\xampp\htdocs\magento\app\Mage.php on line 516
是否需要一个Helper类.我不知道有关帮助器和Data.php的信息
Is it necessary to have a Helper class. I have no idea about the helpers and Data.php
推荐答案
您的模块需要帮助程序类的原因是 system.xml 文件中的module自变量:
The reason your module needs a helper class is the module argument in the system.xml file:
<cashondelivery translate="label" module="cashondelivery">
Magento将module参数传递给Mage::helper()工厂方法.依次将类ID补全为cashondelivery/data.
Magento passes the module argument to the Mage::helper() factory method. This in turn completes the class id to cashondelivery/data.
Mage::helper('cashondelivery');
// identical to Mage::helper('cashondelivery/data');
现在，Magento通过查找缺少的节点global/helpers/cashondelivery/class来检查要使用的类前缀.
Now Magento checks for the class prefix to use by looking for the node global/helpers/cashondelivery/class which is missing.
到目前为止，它还很简单，但是在这里可能有些让人困惑.
如果Magento找不到助手类的前缀，它会尝试通过在类ID的前面加上mage_并附加_helper来弥补.
因此，这将为您提供mage_cashondelivery_helper作为类前缀，并为mage_cashondelivery_helper_data作为完整的类名.
Rather straightforward so far, but here is where it might be a little confusing for some.
If Magento doesn't find a helper class prefix, it tries to makes one up by prefixing the class id with mage_ and appending _helper.
So this gives you mage_cashondelivery_helper as the class prefix, and mage_cashondelivery_helper_data as the full class name.
自动加载器将其转换为 Mage/Cashondelivery/Helper/Data.php ，找不到该文件，因此您遇到的异常.
The autoloader turns this into Mage/Cashondelivery/Helper/Data.php, which can't be found, and hence the exception you are experiencing.
除了创建Companyname_Cashondelivery_Helper_Data类外，还需要将类组映射添加到config.xml文件中，如下所示:
Besides creating the Companyname_Cashondelivery_Helper_Data class, you need to add the class group mapping to your config.xml file as follows:
<global>
<helpers>
<cashondelivery>
<class>Companyname_Cashondelivery_Helper</class>
</cashondelivery>
</helpers>
</global>
您所缺少的只是该类组到类前缀的映射.
This class group to class prefix mapping is all you are missing.
