自定义Magento运输模块出现致命错误 [英] Fatal Error with Custom Magento Shipping Module
问题描述
我对Magento Development还是陌生的，并且无法使自定义运输模块正常工作.我遵循了许多教程，但每次都遇到类似的错误.我当前使用的是此处 .我进行了很多修改，但最终出现了更多错误，因此当前可以将本教程的内容复制到我的magento 1.12.0.2安装中.
I am fairly new to Magento Development and am having trouble getting a custom shipping module to work. I followed numerous tutorials but ended up with similar errors each time. The current one I am using is here. I tinkered with it a lot but ended up with more errors, so I am currently at the stock of this tutorial copied over to my magento 1.12.0.2 installation.
在Sysytem->Config->Shipping Methods下，出现新方法Smashing Magazine Carrier，我可以编辑显示的值.但是，每当我尝试去前端的购物车时，都会收到错误消息:
Fatal error: Call to a member function setStore() on a non-object in /var/www/includes/src/Mage_Shipping_Model_Shipping.php on line 421
Under Sysytem->Config->Shipping Methods the new method, Smashing Magazine Carrier, appears and I can edit the values shown. However, whenever I try to go to the cart on the frontend I get the error:
Fatal error: Call to a member function setStore() on a non-object in /var/www/includes/src/Mage_Shipping_Model_Shipping.php on line 421
和错误:
Fatal error: Class 'Mage' not found in /var/www/includes/src/Mage_Core_Model_Resource_Setup.php on line 378
我很茫然，正在寻找正确方向的任何印记以解决此问题.感谢您的阅读！以下是相关文件:
