Overridding a Shipping Method - What am I missing

Question

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?

Answer 1

it's been a while but I had the same problem the last days. I wanted to override freeshipping and flatrate shipping methods and in addition to the answer of fab I had to add the following code in etc/config.xml. In my case the original values are located in app/code/core/Mage/Shipping/etc/config.xml.

    ...
    
        
            
                your_module/shipping_carrier_flatrate
            
            
                your_module/shipping_carrier_freeshipping
            
        
    

The model values are examples. You have to replace them with your correct paths.
