Practical CodeIgniter 3 - A new book coming soon

Can you put an example how to use a crud with many to many table?

That sounds like a good exercise for the reader.

Actually, if what you're looking for is a mini-ORM, that you should take a look at Avenirer's MY_Model. While I haven't used it before, it incorporates most everything that the MY_Model I've used for several years does, as well as some extra goodies like built-in pagination, and relationships.
