cakephp 2：将变量从控制器传递到元素

Question

I want to pass information from my controller into my element. What cakephp 2 function do I use prior to rendering my element so that my login_ajax element is aware of the value of $error.

This is an abbreviated version of my controller function

public function login($_msg=null) {

    $this->get_post('login');
    $error = false;

    if($this->request->is('post')) {
        if($this->Auth->login()) {
            // REDIRECT TO DASHBOARD
            $this->redirect(array('controller' => 'users', 'action' => 'dashboard'));
        } else {
            $error = true;
        }
    }

    // !! pass $error status to element here !!
    $this->set('element', 'login_ajax');
    $this->render('ajax_modal', 'ajax');
}

And the variable doesn't need to be named $error if that would cause a conflict, it's just an example.

Thanks

您需要添加： $this->set('error',$error)并且在您使用的元素中可以使用$error 。
