Answer 1

Cakephp provides the feature to redirect users back to where they came from.

Its AuthComponent::redirectUrl()

After the login redirect them to redirectUrl like below
$this->redirect($this->Auth->redirectUrl())

First in AppController.php. Inside beforeFilter function store previous url in session

public function beforeFilter(){
  $url = Router::url(NULL, true); //complete url
  if (!preg_match('/login|logout/i', $url)){ // Restrict login and logout actions
    $this->Session->write('prevUrl', $url);
  }
}

Use where you need to redirect

if ($this->Session->read('prevUrl')){
$this->redirect($this->Session->read('prevUrl'));
exit;
}

This is working in cakephp 2.6 change beforeFilter function in cakephp 3 as

public function beforeFilter(\Cake\Event\Event $event){
  $url = Router::url(NULL, true); //complete url
if (!preg_match('/login|logout/i', $url)){ // Restrict login and logout actions
    $session = $this->request->session();
    $session->write('prevUrl', $url);
 }
}

Use where you need to redirect

$session = $this->request->session();
if($session->read('prevUrl')){
   $this->redirect($session->read('prevUrl'));
   exit;
}
