I'm reading Magento 1.3: PHP Developer's Guide by Jamie Huskisson and there is a guide on how to do a custom shipping module. I get no visible errors when the module is enabled but I can't see it showing up Configuration -> Shipping Methods.
Here is an image of how it looks for me: https://i.imgur.com/Et4LVcI.png
It should list a carrier named "Bare Bones Shipping inc.", as displayed in the book. I have reviewed my code but I can't find anything wrong.
Could it be because I'm using a later version of Magento (22.214.171.124) instead of 1.3? If so, what should I do different?
Just ask me and I will provide the code as it would take up too much space if I included it here.
I don't remember that example but maybe you could check one of these:
