Redirect to the last page requested after login in cakephp

Question

1. HI I have search from where client can either click on keywords which is below in search bar or enter a keyword in search window, In case first when user click on keywords the search_results opens with keywords in URL but when user enter keyword then it just give result according to it.
2. So when user not logged in then after some search_result we ask for login & on click login button we redirect for login popup from where user logged in that time we have to redirect on same page so for this I am using two concept one for predefined keywords link which come on URL just redirect last URL value in session & after logged in redirect to that URL.

3.I need help in keyword enter by user & then logged in so needs to redirect with same keyword page to user.

function search_result($adKeyword = null){

    if(!empty($adKeyword) && $adKeyword != ''){

        $this->data['City']['keyword'] = $adKeyword;
    }
    //////////////////Maintain fetch data////////////////////
    if(!empty($this->data)){    
        //pr($this->data);exit;
        if($this->data['City']['keyword'] == 'Name or Area of expertise'){
            $this->data['City']['keyword'] = '';
            $this->set("title_for_layout","Search Result");
        }

        if ( empty($this->data['City']['city_name'])) {

            $this->data['City']['city_name'] = $this->Session->read("Location");
        }

        if($this->data['City']['keyword'] != '')
            $this->set("title_for_layout",$this->data['City']['keyword']." | Search Result");
                       //$request_params = Router::getParams();
                          //$this->Session->write('auth_redirect','/'.$request_params['url']['url']);
                    $this->Session->write('login_referrer',$this->params['url']['url']);
                    $this->Session->write('login_referrers',$this->data['City']['keyword']);

above two session variable I am using for redirect after authentication on login

    if($this->Auth->user('role_id')== Configure::read('App.Role.Mentee')) {
                        if ($this->Session->check('login_referrer')) {
                                   $loginReferrer = $this->Session->read('login_referrer');
                                   $this->Session->delete('login_referrer');
                                   //prd($loginReferrer);  
                                   $this->redirect(SITE_URL."$loginReferrer");
                                   }
                                  else if($this->Session->check('login_referrers'))
                                   {

                                   $loginReferrers = $this->Session->read('login_referrers');
                                   $this->Session->delete('login_referrers');
                                   //prd($loginReferrers);  
                                   $this->redirect(array('controller'=>'fronts','action'=>'search_result/','$adKeyword' => $loginReferrers));
                                   }
                                  else {
                                  $this->redirect(array('controller'=>'fronts','action'=>'index'));
                                  }

what happening its not going to else if statement Please help me

Answer 1

If they are browsing some pages and asked to login then they should redirect to that page after login

That's exactly what the Auth component does by default . As such to get the desired behavior, the login function should look similar to:

public function login() {
    if ($this->request->is('post')) {
        if ($this->Auth->login()) {
            return $this->redirect($this->Auth->redirect());
        }
        $this->Session->setFlash(__('Invalid username or password, try again'));
    }
}

Note the use of $this->Auth->redirect() which returns the url to redirect the user to, this example is taken directly from the documentation .

To change the default Auth redirect url modify the loginRedirect property of the auth component (from your beforeFilter, for example).

For manually login I have solved my issue,I have added this code to search_result action of my front_controller

 $request_params = Router::getParams();
$this->Session->write('auth_redirect','/'.$request_params['url']['url']);

And in my user _controller I have just used this session variable:

if($this->Auth->user('role_id')== Configure::read('App.Role.Mentee')) {
$this->redirect($this->Session->read('auth_redirect'));
else
                                  $this->redirect(array('controller'=>'fronts','action'=>'index'));

But it is not solving my problem completely, I want to delete session value after one time redirect.but for this it is not destroying the router session variable value
