Question

Access $this->params and $this->data in components.

class LoginComponent extends Object {
   /*  */
   public function login() {   
      pr($this->params);
      pr($this->data);
   }
}

I am using this in cake v1.2. I would like to know solution of this in v1.2 as well as v2.1. Please give me a suggestion.

Have a look at some components in your lib. I know this for Cake 2.x, not for 1.2.x. update: as mark mentioned in the comments, this works the same for the 1.x versions.

For example, when I open the SecurityComponent I will find a function called startup(). This method defines itself as:

public function startup(Controller $controller) {
     //Rest of code goes here
}

as you can see, they import the Controller object. What you could right now is access the Controlelr methods and variables. Because as you might know: the $this when calling $this->data refers to the Controller.

So, if I store this $controller in a protected variable called $_Controller in my component, I can easily access the data and params like so:

# CakePhp 2.x
$this->_Controller->request->data;
$this->_Controller->request->params;

# CakePhp 1.x
$this->_Controller->data;
$this->_Controller->params;

Have a look at this answer as well.
