Question

I want to create three new order attribute for checkout page, so I found good tutorials to create using install script but I want to add text boxes to checkout page and save it to database,

Are there any simple solution ? ( free module )

Answer 1

To add a new checkout field, save a value in the database and display in the backend is very long process, there are lots of paid extension available for this but I would afraid suggest you look into below link, In this link, they are adding date picker you can replace with textbox. And step by step by guidance is worth to read.
