title: how to use $this->request->param of Kohana to get request variables
body: <p>I have written  a sample controller in kohana </p>
  
  <pre><code>    &lt;?php
  
  defined('SYSPATH') OR die('No direct access allowed.');
  
  class Controller_Album extends Controller {
  
    public function action_index() {
      $content=$this-&gt;request-&gt;param('id','value is null');   
      $this-&gt;response-&gt;body($content);
    }
  
  }
  </code></pre>
  
  <p>But when I am trying to hit url <a href="http://localhost/k/album?id=4" rel="noreferrer">http://localhost/k/album?id=4</a>
  I am getting NULL value. 
  how can I access request variable in kohana using request->param and without using $_GET and $_POST method ?</p>
