Adding an Extension to replace the default text fields in billing infromation in onepage checkout

[bivin_damodhar]

I have developed an extension to list the provinces and cities for the South Africa.I need to use this extension in the billing information section in the one page checkout(replacing the existing fields country,state/province, cities) how should I do this

Hi bivin,

Could this not be archived by editing the onepagecheckout files and then extending/referencering your code in these files from your module ?

If you build a module, I would assume you have the skills to do this or did I misunderstand your question

Hi @bivin_damodhar 

With One Step Checkout by Magegiant.com

You can edit default attributes and create unlimited new attributes in Checkout page without changing a line of code.

Thanks Kent,

Did you try the custom checkout fields module by FMEExtensions?

Why would you need any extension?  just populate the directory_country_region, directory_country_region_name  table in magento for your coutry and you will be good to go.
