Intégration de Zend et Smarty 3 en utilisant

Question

J'essaye de changer le contenu de la disposition dans mon contrôleur, qui semble seulement l'écraser, seulement ajouter.

J'ai construit un CMS en utilisant Zend et Smarty. J'ai une mise en page principale avec, qui affiche le contenu de chaque page:

{$this->layout()->content} 

Bien que lorsque je tente de remplacer le « contenu » dans le contrôleur avec une nouvelle zone de contenu ce qui provoque à la fois l'indice/index.tpl et Contact/contact.tpl à afficher:

$this->view->content = $this->view->display('contact/contact.tpl'); 

Je sais que je pourrais assigner manuellement le contenu à une variable smarty vue, bien que je voudrais réduire les cessionnaires de Smarty et utiliser Zend.

Dans mon application.ini

smarty.caching = 1 
smarty.cache_lifetime = 14400 
smarty.template_dir = PATH "/templates/default/" 
smarty.compile_dir = PATH "/tmp/smarty_compile/" 
smarty.plugins_dir = APPLICATION_PATH "/plugins/smarty/" 
smarty.config_dir = "" 
smarty.cache_dir = PATH "/tmp/smarty_cache/" 
smarty.left_delimiter = "{" 
smarty.right_delimiter = "}" 

Dans mon bootstrap.php

protected function _initView() 
{ 
    $view = new Web_View_Smarty($this->getOption('smarty')); 
    $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('ViewRenderer'); 
    $viewRenderer->setViewSuffix('tpl'); 
    $viewRenderer->setView($view); 
    $this->bootstrap('layout'); 
    $layout = Zend_Layout::getMvcInstance(); 
    $layout->setViewSuffix('tpl'); 
    return $view; 
} 

Dans mon smarty.php

Answer 1

Il est dans la mise en œuvre Smarty Documentation Zend. Smarty est mauvais, tout moteur de template est mauvais et ralentit votre application. Utilise les vues zend natives. Et rappelez-vous que PHP a été inventé pour être un moteur de template. http://framework.zend.com/manual/1.11/en/zend.view.scripts.html

Answer 2

Lorsque dans votre modèle, vous écrivez

{$this->layout()->content} 

Ceci est le contenu de l'aide de la mise en page, qui rend la vue associée à chaque action.

Lorsque, en vous contrôleur, vous écrivez

$this->view->content = $this->view->display('contact/contact.tpl'); 

Vous attribuez une variable à votre point de vue, qui peut être l'affichage, en utilisant

{$content} 

dans votre modèle de Smarty.

Je pense que vous avez une certaine confusion dans votre façon de régler cela. Jetez un oeil à http://framework.zend.com/manual/1.12/en/zend.layout.quickstart.html

De toute façon, votre question est ancienne et vous avez déjà choisi une réponse correcte, ce qui n'était pas vraiment une réponse, mais je ne pouvais pas passer et ne rien dire. L'utilisation de Smarty avec Zend est super, Smarty est plus rapide et la compilation/mise en cache a un meilleur réglage que Zend et l'intégration entre les deux est soignée (grâce à l'injection de dépendances). Vous pouvez avoir la puissance des deux bibliothèques dans une application, alors allez-y.
