問題描述

我以前寫過很多模塊，但由于某種原因，我的運輸模塊不會覆蓋現有的萬磁王運輸方式.允許嗎?我在這里錯過了什么?模塊名稱顯示在配置區域的高級選項卡中，因此它正在加載，但什么也沒有發生.任何提示?

I've written many many modules before but for some reason my shipping module won't override an exsiting Magneto shipping method. Is that allowed? What am I missing here? The module name shows up in the advanced tab of the configuration area, so it's getting loaded, but nothing is happening. Any hints?

推薦答案

在仔細研究這個之后，我發現覆蓋傳送控制器的唯一方法是在本地代碼文件夾.然后我基本上可以調整代碼.

After working through this one a bit, I found that the only way to override the shipping controller was to make a duplicate of the file (and directory structure) in the local code folder. Then I could basically tweak the code.

不知道為什么 Magento 似乎不允許標準覆蓋這些傳送功能，但至少有一個解決方法.

Not sure why Magento doesn't seem to allow the standard overriding of these shipping functions, but a least there is a work around.
