我正在尝试根据我的路线更改布局,这是我到目前为止所做的事情:
<?php namespace Application\Listener;
use Zend\EventManager\AbstractListenerAggregate;
use Zend\EventManager\EventManagerInterface;
use Zend\Mvc\MvcEvent;
use Zend\View\Model\ModelInterface as Model;
class LayoutListener extends AbstractListenerAggregate
{
/**
* Attach one or more listeners
* Implementors may add an optional $priority argument; the EventManager
* implementation will pass this to the aggregate.
* @param EventManagerInterface $events
* @return void
*/
public function attach(EventManagerInterface $events)
{
$sharedEvents = $events->getSharedManager();
$this->listeners[] = $sharedEvents->attach(
'Zend\Mvc\Controller\AbstractController',
MvcEvent::EVENT_DISPATCH,
array($this, 'handleLayouts'),
-99);
}
public function handleLayouts(MvcEvent $event)
{
$viewModel = $event->getViewModel();
if (!$viewModel instanceof Model) {
return;
}
$routeMatch = $event->getRouteMatch();
$resolver = $event->getApplication()
->getServiceManager()
->get('Zend\View\Resolver\TemplatePathStack');
if ('Application\Controller\Index' !== $routeMatch->getParam('controller')) {
return;
}
switch ($routeMatch->getParam('action')) {
case 'index':
$template = 'layout/layout';
break;
case 'home':
$template = 'layout/home';
break;
default:
$template = null;
break;
}
/**
*
* Don't know why, but to set a template must use $event->getViewModel()
* and for terminal must use $event->getResult(), otherwise it won't works
*
*/
// if template is resolvable, use it, otherwise go terminal
if ($template && $resolver->resolve($template)) {
$viewModel->setTemplate($template);
} else {
if ($event->getResult() instanceof Model) {
$event->getResult()->setTerminal(true);
$viewModel->setTerminal(true);
}
}
}
}
Module.php
public function onBootstrap(MvcEvent $e)
{
$translator = $e->getApplication()->getServiceManager()->get('translator');
$translator->setLocale(\Locale::acceptFromHttp($_SERVER['HTTP_ACCEPT_LANGUAGE']))
->setFallbackLocale('en_US');
$eventManager = $e->getApplication()->getEventManager();
$eventManager->attachAggregate(new LayoutListener());
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
}
有一件事我没有得到,如果我想改变布局,我必须使用
$event->getViewModel()->setTemplate($template);
否则它将无法工作,如果我想设置viewModel终端,我必须使用
$event->getResult()->setTerminal(true);
否则它将无效,有人可以解释我为什么?
我正在努力实现它的目标如下:我有一个索引模板/初始化加载任何其他路径内容的iFrame,所以在索引布局中我设置了菜单,任何其他页面都没有需要有一个布局,因为使用索引/一个。
现在我想要一个具有自定义布局(自定义显示)的子页面,因此,根据路径,我为viewmodel设置了一个新的布局。
答案 0 :(得分:1)
您可以将子视图添加到视图模型中(如果您在Controller中) - 如果您为子视图(或子页面)创建自己的控制器:
$view = new ViewModel(array(
// parameters
));
$view->addChild($this->forward()->dispatch('SubpageController', array(
'action' => 'index',
)), 'contentOfSubpage');
return $view;
在模板中,您可以像这样访问SubpageController的内容:
<?php echo $contentOfSubpage; ?>
至少,这就是如何组合多个控制器,因此不同的布局
