Session->flash is not showing session message in CakePHP

Question

I'm using CakePHP 2.6.7 and copied the code to show flash messages from one controller to another, but it's not working in the second controller.

In AdminsController:

   function login() {
        $this->loadModel('Admin');
        $this->layout = "admin-login";
        // if already logged in check this step
        if ($this->Auth->loggedIn()) {
            return $this->redirect('dashboard'); //(array('action' => 'deshboard'));
        }
        // after submit login form check this step
        if ($this->request->is('post')) {
            if ($this->Auth->login()) {
                // pr($this->Auth); exit;
                if ($this->Auth->user('status') == 'active') {
                    // user is activated
                    $this->Admin->id = $this->Auth->user('id');
                    $this->Admin->saveField("loggedIn", 1);
                    return $this->redirect($this->Auth->redirectUrl());
                } else {
                    // user is not activated
                    // log the user out
                    $msg = '<div class="alert alert-error">
                           <button type="button" class="close" data-dismiss="alert">×</button>
                           <strong>You are blocked, Contact with Adminstrator</strong>
                        </div>';
                    $this->Session->setFlash($msg);
                    return $this->redirect($this->Auth->logout());
                }
            } else {
                $msg = '<div class="alert alert-error">
                           <button type="button" class="close" data-dismiss="alert">×</button>
                           <strong>Incorrect email/password combination. Try Again</strong>
                        </div>';
                $this->Session->setFlash($msg);
            }
        }
    }

In admins/login.ctp:

<?php echo $this->Session->flash(); ?>

When I type wrong email or password it shows error message. proof: http://jegeachi.com/admins/login

But SAME task cannot be done in ResellersController. Here is the controller code:

function login() {
    $this->layout = 'public-login';
    $this->loadModel('Reseller');
        // if already logged in check this step
    if ($this->Auth->loggedIn()) {
            return $this->redirect('profile'); //(array('action' => 'deshboard'));
        }
        // after submit login form check this step
        if ($this->request->is('post')) {

            if ($this->Auth->login()) {

                return $this->redirect($this->Auth->redirectUrl());
            } else {

                $msg = '<div class="alert alert-error">
                <button type="button" class="close" data-dismiss="alert">×</button>
                <strong>Incorrect email/password combination. Try Again</strong>
            </div>';
            $this->Session->setFlash($msg);

        }
    }
} 

in Resellers/login.ctp:

 <?php echo $this->Session->flash(); ?>

When login failed due to wrong email or password it is not being showed.

Its a strange and wired problem. Same code work in a controller but not in other. Any idea?

Answer 1

Make sure you are not already consuming the Session flash message. This could happen if you have in your app/View/Layouts/public-login.ctp layout something like:

<?php $this->Session->flash(); ?>

Or somewhere in your view/view blocks.

Checking the HTML output, I have found the following instead of the expected error message:

    <div class="alert alert-danger display-hide">
        <button class="close" data-close="alert"></button>
        <span> Enter Email and password. </span>
    </div>

Check your beforeRender() callback and make sure you are not flashing the above message. If you are, it's overwriting the previous one.

Hello I think you have forgot to echo your session message please write like below In your ctp file

echo $this->Session->flash();
