[英]How to call model class method from controller in megento?
I have created a new model class in checkout/type name Cartpage.php and it has a method name addValue($id)
. 我在结帐/类型名称Cartpage.php中创建了一个新的模型类,它具有方法名称addValue($id)
。 Want to call this model class method from saveShippingMethodAction()
in OnepageController.php at Checkout/controllers. 要从Checkout / controllers的OnepageController.php中的saveShippingMethodAction()
调用此模型类方法。 I have called in several ways but it gives me an error: 我已经以几种方式打电话给我,但它给了我一个错误:
Fatal error: Call to a member function addValue() on a non-object in .../app/code/core/Mage/Checkout/controllers/OnepageController.php 致命错误:在... / app / code / core / Mage / Checkout / controllers / OnepageController.php中的非对象上调用成员函数addValue()
I have tried: 我努力了:
$myModel = Mage::getSingleton('checkout/cartpage');
$return = $myModel->addValue($my_value);
Model: 模型:
class Mage_Checkout_Model_Type_Cartpage extends Mage_Sales_Model_Quote_Address_Total_Abstract
{
public function addValue($value)
{
return $value;
}
}
How can I call my custom model from OnepageController? 如何从OnepageController调用自定义模型?
If your module is located under Checkout/Model/Type/Cartpage.php
the correct classgroup
to call is checkout/type_cartpage
如果您的模块位于Checkout/Model/Type/Cartpage.php
, classgroup
调用的正确类classgroup
是checkout/type_cartpage
so use Mage::getSingleton('checkout/type_cartpage');
因此请使用Mage::getSingleton('checkout/type_cartpage');
instead of Mage::getSingleton('checkout/cartpage');
而不是Mage::getSingleton('checkout/cartpage');
However it looks like you are adding your model class under the core
namespace which is a nogo in magento. 但是,似乎您要在core
名称空间下添加模型类,这是magento中的nogo。
create you own module und the local
namespace and create rewrites
for the parts you want/need to change 创建您自己的模块和local
名称空间,并为要/需要更改的部分创建rewrites
