How to load a controller from another controller in codeigniter?


I want to load a controller from a function in another controller because the library I integrated to my project I don't want to load it to the controller because I want to keep it clean and related.

I tried using modules but I still had to put controller in the url like

http://example.com/maincontroller/function
http://example.com/othercontroller/function

I have default controller so I can load http://example.com/function so how could I access the controller from a function from main so I don't have to put the controller in the url.

I'm still willing to use HMVC if I can load the controller function from the main controller function.


Answers:


You can't load a controller from a controller in CI - unless you use HMVC or something.

You should think about your architecture a bit. If you need to call a controller method from another controller, then you should probably abstract that code out to a helper or library and call it from both controllers.

UPDATE

After reading your question again, I realize that your end goal is not necessarily HMVC, but URI manipulation. Correct me if I'm wrong, but it seems like you're trying to accomplish URLs with the first section being the method name and leave out the controller name altogether.

If this is the case, you'd get a cleaner solution by getting creative with your routes.

For a really basic example, say you have two controllers, controller1 and controller2. Controller1 has a method method_1 - and controller2 has a method method_2.

You can set up routes like this:

$route['method_1'] = "controller1/method_1";
$route['method_2'] = "controller2/method_2";

Then, you can call method 1 with a URL like http://site.com/method_1 and method 2 with http://site.com/method_2.

Albeit, this is a hard-coded, very basic, example - but it could get you to where you need to be if all you need to do is remove the controller from the URL.


You could also go with remapping your controllers.

From the docs: "If your controller contains a function named _remap(), it will always get called regardless of what your URI contains.":

public function _remap($method)
{
    if ($method == 'some_method')
    {
        $this->$method();
    }
    else
    {
        $this->default_method();
    }
}
