Multiple Actions in one Controller - Symfony2

i have a complex form. This form is created in the controller A. All actions, like: edit, add, load, index are in the controller A defined and the method actionIndex is essential for all other requests.

Like this schema:

public class controllerA  {


function actionIndex(Requerst r){

    r.handleRequest();

    if ($form->get('index')->isClicked()){
      // Index Action
    }
    if ($form->get('add')->isClicked()){
      $this->actionAdd();
    }
    // ...
}
function actionAdd(){}

}

}

How do i seperate the requests in different controllers? Actually it doesnt feel good.

Here my actual code of the controller: http://pastebin.com/HuXhV37q

Solution

I have skimmed through your code and I speak german so I understand it.

It would be too much to cover here so I just give you some "keywords".

Outsource business logic from controllers to symfony services to keep the controllers light. ($zusaetzeArray etc.)

Create Entities and FormTypes for the form data if it makes sense economically.

Create multiple controller actions with corresponding routes for the different form states.
