Ben giriş gerektirir uygulamanın içeriğinin dışında herhangi bir eylem irade dahil edilebilir bir giriş aracı oluşturmak için çalıştık. Benim buradaki düşünce ben bir önceki oturum açma girişimi herhangi bir hata mesajları ile giriş kutusu render için KURU yaklaşım istedim oldu. Bunu etkinleştirmek için ben başarısız oturum açma-girişimi sonucu tasarrufu için FlashMessenger kullanılmaktadır. Widget da tarayıcı arka düğme kullanarak verileri birden çok kez gönderme sorunu önlemek için Post/Redirect/Get-pattern kullanır.
Şimdi, sorun ben daha ziyade bu yardımcı klonlarının isteği beri Zend_View_Helper_Action kullanın ve yoğun oldukça kaynaktır gönderme-döngü, başka çalıştırmak oluşturur olmaz olmasıdır. Yani, aşağıdaki kodu bakarak, bana öyle ki kod refactor konusunda bazı tavsiyeler verebilir:
- The widget can be included in an arbitrary view script
- Results from a previous login attempt is rendered
- The widget does not invoke a run in the dispatch-loop
Şu anda, giriş Widget görünümü komut dosyalarında, arayarak işlenir:
echo $this->action('auth', 'login-widget');
AuthController.php:
class AuthController extends Zend_Controller_Action {
// This method is invoked by Zend_View_Helper_Action to render the
// login widget
public function loginWidgetAction () {
$flashMessenger = $this->_helper->flashMessenger->setNamespace('login');
$this->view->messages = $flashMessenger->getMessages();
}
public function loginAction () {
if($this->getRequest()->isPost()) {
$result = Auth::doLogin($this->getRequest()->getPost());
if($result->isValid()) {
$this->_redirect('user');
}
else {
$flashMessenger = $this->_helper->flashMessenger->
setNamespace('login');
foreach($result->getMessages() as $message) {
$flashMessenger->addMessage($message);
}
}
}
// This will be changed to redirect either to the index page,
// or the page the request originated from if available.
$this->_redirect('');
}
