Cookie is not working in CakePHP , CookieComponent is not working - cakephp

Question

This is my AdminsController class where I have included the Cookie Component, and used the cookie creation code given below in #1. #2 is the code I am using in my view.
Whenever I fire the url, it is showing the error: "Helper class CookieHelper could not be found.".
Why is this error is showing, as I have asked to use CookieComponent to set and get the value of the cookie. I have followed instructions and code syntax from the CakePHP docs that they have provided on their website. I'm really having trouble on setting and getting the cookie. I need help on this. The CakePHP version that i'm using is 2.6.
#1 - Controller:
class AdminsController extends AppController {
/**
* This controller does not use a model
*
* #var array
*/
//public $uses = array('Admin');
/**
* Displays a view
*
* #return void
* #throws NotFoundException When the view file could not be found
* or MissingViewException in debug mode.
*/
public $components = array('Cookie');
public function index() {
$this->layout=false;
//echo "=users index====";
//$this->layout = 'adminlayout';
if($this->request->is('post'))
{
$username = $this->request->data['Admin']['username'];
$password = $this->request->data['Admin']['password'];
$remember_me = $this->request->data['Admin']['remember_me'];
$sql = $this->Admin->find('count',array(
'conditions' => array('Admin.username'=>$username,'Admin.password'=>md5($password))
));
//$this->Session->write('is_admin_login','Y');
if($sql>0)
{
$this->Session->write('is_admin_login','Y');
if(!empty($remember_me))
{
//*** set cookie starts
if($this->Cookie->check('username_cookie'))
{
$this->Cookie->delete('username_cookie');
$this->Cookie->write('username_cookie', $username, false, '30 Days');
}
if($this->Cookie->check('password_cookie'))
{
$this->Cookie->delete('password_cookie');
$this->Cookie->write('password_cookie', $password, false, '30 Days');
}
//*** set cookie ends
}
else
{
if($this->Cookie->check('username_cookie'))
{
$this->Cookie->delete('username_cookie');
}
if($this->Cookie->check('password_cookie'))
{
$this->Cookie->delete('password_cookie');
}
}
$this->redirect('/admin/home');
}
else
{
$this->Session->setFlash('Invalid username or password','default',array('class'=>'error_msg'));
}
}
$this->render('admin_login');
}
}

Answer 1

You are trying to use a Component in a view, which is why it is telling you there is no helper class called Cookie.
Use the Cookie component in your Controller action to set a variable, and then use the variable in your view:
Remove these lines from your view:
$this->Cookie->check('username_cookie')
$this->Cookie->check('password_cookie')
Use them in your controller action to set view variables ...something similar to:
$this->set('username_cookie', $this->Cookie->read('username_cookie'));
$this->set('password_cookie', $this->Cookie->read('password_cookie'));
Then you will be able to use the set variables in your view:
if(!empty($username_cookie)) {
//do something
}
//or
if(!empty($password_cookie)) {
//do something
}
