Hi! I'm making a FB Connect site. I have a multi-friend selector. When i send invitations, the user is sent to root. Root is albums/index (because there are picture cards albums). Because the application could have only one album, when I just have one album I sent the user straight to that album.
So I have:
function index() {
$albums = $this->Album->find('all');
//If there's only 1 album, we go straight to the album!
if (count($albums) == 1) {
$this->choose($albums[0]['Album']['id']);
}
}
function choose($aid) {
$album = $this->Album->findByIdAndApplicationId($aid,Configure::read('Application.id'));
if (empty($album)) {
throw new Exception("Invalid album id");
//$this->getBack("Invalid album");
}
$this->Session->write('Auth.User.album_id', $aid);
$this->Session->write('Auth.User.album_name',$album['Album']['name']);
$this->redirect('/albums/view');
}
function view($page = 1) {
$uid = $this->Auth->user('user_id');
$this->loadModel('User');
$user = $this->User->find('first', array(
'contain'=>array(
'Card'
),
'conditions'=>array('User.id'=>$uid)
));
$cardsPerPage = Configure::read('Album.CardsPerPage');
$offset = ($page-1) * $cardsPerPage;
if (!$this->Session->check('Auth.User.album_id')) {
//HERE IS THE PROBLEM
$this->Session->setFlash("Choose an album");
$this->redirect('/albums/');
}
The problem is that for some reason, this
$this->Session->write('Auth.User.album_id', $aid);
$this->Session->write('Auth.User.album_name',$album['Album']['name']);
is lost when I redirect to albums/view, then this code is executed:
$this->Session->setFlash("Choose an album");
$this->redirect('/albums/');
And I have an infinite loop.
Why this could happen? All other Session variables are ok when I do a debug. Only that variables are lost.
This problem appears ONLY when I come from a Facebook callback (like after sending invitations, or clicking in a Facebook link). When I go to /albums/index by myself I am well redirected to albums/view with the only album selected.
I think may have to do with the fact I'm using Auth.User session space to store other fields.... but it's strange it only happens with Facebook.
