Re: passing ID from one controller to another

Well, if you're on a post page, and writing a comment there, don't you already know what the Post ID is?

You can just include the Post ID in the comment for, via a hidden field.

echo $this->Form->input('id', array('type' => 'hidden'));

public function isAuthorized($user) {

        return true;

    }

    return parent::isAuthorized($user);

}

    public function add() {

    if(!($post = $this->Post->findById($id)))

        if ($this->request->is('post')) {

        $this->request->data['Comment']['user_id'] = $this->Auth->user('id');

        $this->request->data['Comment']['post_id'] = $post['Post']['id'];  // HOW CAN I IDENTIFY POST ID FROM PostsController.php    ????? //

                $this->redirect(array('controller' => 'posts', 'action' => 'index'));
