Is it possible to call methods from one controller on another in Codeigniter?

Question

If I am in a "signin" controller can I execute the method get_user_info() which resides in the "user" controller? If so, what would be the syntax for that?

Answer 1

I'm not saying this can't be done, however it really shouldn't be done.

Something like this is exactly what a library is meant for.

Create a library which handles functions such as get_user_info() and then load and call that library within whichever controllers need access to it.

You can still have a controller named user and a library named user as well (though that could get confusing).

Check out CI's guide for info on how to create a library .

* Edit *

As people have mentioned models could also serve the purpose of making functions usable in multiple places.

Personally I like to keep only business logic within models (the CRUD operations) and any logical operations which must be done in multiple places I create a library for.

have you looked at HMVC?
https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc/wiki/Home

it will look something like modules::run('module/controller/method', $params, $...);
