I agree that the way to do is to redirect to the new controller in usual cases   I came across a use case where I needed to display the same page to 2 different kind of users  backend user previewing the page of a frontend user  so in my opinion what I needed was genuinely to call the frontend controller from the backend controller   I solved the problem by making the frontend method static and wrapping it in another method  Hope it helps                   Frontend              function profile          Access check       Get profile id     id   get user id        return self   profile  id      static function  profile  id        CI    amp get instance         Prepare page      Load view                    Backend              function preview profile  id        this- gt load- gt file  controllers frontend php   false       Frontend   profile  id

This is not supported behavior of the MVC System  If you want to execute an action of another controller you just redirect the user to the page you want  i e  the controller function that consumes the url    If you want common functionality  you should build a library to be used in the two different controllers   I can only assume you want to build up your site a bit modular   I e  re-use the output of one controller method in other controller methods   There s some plugins   extensions for CI that help you build like that  However  the simplest way is to use a library to build up common  controls   i e  load the model  render the view into a string   Then you can return that string and pass it along to the other controller s view   You can load into a string by adding true at the end of the view call    string view    this- gt load- gt view  someview   array  data   gt  stuff    true

I posted a somewhat similar question a while back  but regarding a model on CI   Returning two separate query results within a model function  Although your question is not exactly the same  I believe the solution follows the same principle  if you re proposing to do what you mention in your question  there may be something wrong in the way you re coding and some refactoring could be in order   The take home message is that what you re asking is not the way to go when working with MVC   The best practice is to either use a Model to place reusable functions and call them in a controller that outputs the data through a view -- or  even better use helpers or libraries  for functions that may be needed repeatedly
