My question is about creating update for a custom module extension that I have made.
I have no idea where to begin. So breafly here is what my module does
- It create a database table
- Stores data from a form
- Show them backend in grid
Now the forms have to have more options. but my table dont have enough colums.
So my question is
How do i make an update for my module, that update my tables and update the output to my backend grid?
