Calling a controller within a controller (no URL redirect)

[eluser]Tjunction[/eluser]
Is this possible at all? Not in the redirect the user to a different URL sense, but to call a method on a different controller, receive the response, use this in the same method and then echo the result out to the user.

I have require_once'd the controller in question, then added the following;

Code:

$runsheet_controller = new Runsheet_controller();

But this errors out with the following -

A PHP Error was encountered
Severity: Notice
Message: Undefined property: Runsheet_controller::$controller_session
Filename: job/Runsheet_controller.php
Line Number: 104

I've had a bit of a look over the load function of CI etc, but as far as I can see it can't load a controller... any help would be much appreciated

It's typically not a good idea to call the functions of one controller in another. If you need public access to functions, it might be worth looking into putting the code in a library or helper, and loading it that way.

Thanks for the response!

In this instance I don't think it is worth creating as a library or helper, the method I want to use in question really belongs to the other controller (create_runsheets on runsheet_controller) and it's just a once off on a schedule controller.

The schedule_controller needs to pass an array of runsheet_items it has created to the runsheet_controller, which then groups the items by region and creates a runsheet for each.

Is it possible at all?

You could try some clever trickery with redirects, flash data, and conditionals, but I'm leaning to what prodigy said. Encapsulate the functionality into a library or helper and then you can call it from wherever you need.

Is the runsheet_controller ever called as a controller, or is it just there to assist the schedule_controller? I don't think CI allows calling one controller method from a different controller. The only ways I can think of doing it is to setup your app with one of the modular extensions (HMVC or Matchbox) which allow calling a module controller from a different module, or just cURL-ing your array to the full domain path of that controller.

Yeah the runsheet_controller has it's own view, JS panel's etc, it just sucks that this one and only time I need to call it from a different controller I can't :p

Oh well. I guess I'll go with the library idea, thanks for your advice everyone, much appreciated

Modular Extensions PHP5 may be what you're looking for here. (see my signature)

Try using forum search before posting when you have a problem too, this topic has been discussed many times.

In the MVC paradigm, controllers respond to a user action (through a submitted form or an url). It must do only that !

Any other actions (DB access set apart), must be in classes or functions (thus library or helper).

The normal (and only one) flow is :
one action requested
-> one controller perform the action by using models to get data access, work on them
-> call a new view to display the result of the action

But there are case where within a controller, one must perfom another action. For instance from a list of anything, when a new instance is created, once done, we would like to request a list refreshing.
2 choices :
- display an intermediate view : instance created
- redirect ('list action', 'location') which performs a back & forth to the client
