默认情况下,页面在Application
module.config数组中设置如下:
'template_map' => array(
'error/404' => __DIR__ . '/../view/error/404.phtml'
我想要更改页面。我希望新的ViewModel
充满变量。这意味着仅仅改变模板是不够的:
'error/404' => __DIR__ . '/../view/error/my_new_404_template.phtml'
但我无法理解如何制作它。我无法看到请求到'error/404'
的方式。
如何为它创建新的ViewModel
?
如何将变量附加到它?
路由如何通过'error/404'
来改变它?
例如,我有'error/404'
页面的这种方法:
public function pageNotFoundAction() {
$view = new ViewModel();
$view->setTemplate('error/404'); // set my template
$sm = $this->getServiceLocator()->get('SessionManager');
$cont = new Container('SomeNamespace', $sm);
$view->var1 = $cont->offsetGet('someValue1'); // the "error/404" template
$view->var2 = $cont->offsetGet('someValue2'); // is full of variables
$view->var3 = $cont->offsetGet('someValue3');
$view->var4 = "One more view variable";
// And now I return it somewhere and want it to be called
// in case of "the page is not found"
return $view;
}
如何做出这样的改变?我无法获得他们创建的系统来处理'error/404'
之类的事情。请帮忙。
UPD 1
更复杂的任务。如何拥有多个'error/404'
页面?
想问一下创建框架的人是否知道'not_found_template'
不能拥有'error/404'
个页面的数组。它怎么样?如果我像这样设置这个选项:
'template_map' => array(
'error/404' => __DIR__ . '/../view/error/404.phtml',
'my-page/one_more_error404' => __DIR__ . '/../view/my-page/my-page/one_more_error404.phtml',
'other_page/second_404' => __DIR__ . '/../view/other-page/one_more_error404.phtml',
'not_found_template' => array(
'error/404',
'my-page/one_more_error404',
'other-page/second_404',
);
它会抛出错误。 'not_found_template'
强迫您只拥有一个'error/404'
模板?

还有另一种方式。捕获EVENT_DISPATCH_ERROR
并完全重建viewModel
。 Cavern是布局 - 是根viewModel
,默认情况下附加到布局中的内容是另一个viewModel
(子)。官方文档中没有明确说明这些要点。
以下是Module.php
:
public function onBootstrap(MvcEvent $event)
{
$app = $event->getParam( 'application' );
$eventManager = $app->getEventManager();
/** attach Front layout for 404 errors */
$eventManager->attach( MvcEvent::EVENT_DISPATCH_ERROR, function( MvcEvent $event ){
/** here you can retrieve anything from your serviceManager */
$serviceManager = $event->getApplication()->getServiceManager();
$someVar = $serviceManager->get( 'Some\Factory' )->getSomeValue();
/** here you redefine layout used to publish an error */
$layout = $serviceManager->get( 'viewManager' )->getViewModel();
$layout->setTemplate( 'layout/start' );
/** here you redefine template used to the error exactly and pass custom variable into ViewModel */
$viewModel = $event->getViewModel();
$viewModel->setVariables( array( 'someVar' => $someVar ) )
->setTemplate( 'error/404' );
});
}

我用它来管理404错误(我将我的网站从spip移到了基于ZF2的cms):
在模块onBootstrap函数中:
$eventManager->getSharedManager()->attach('*', MvcEvent::EVENT_DISPATCH_ERROR, array($this, 'onDispatchError'), -100);
然后
public function onDispatchError(MvcEvent $event)
{
$response = $event->getResponse();
if ($response->getStatusCode() == 404) {
$url = $event->getRouter()->assemble(array(), array('name' => 'index'));
$requestUri = $event->getRequest()->getRequestUri();
$response->getHeaders()->addHeaderLine('Location', "$url?url=$requestUri");
$response->setStatusCode(200);
$response->sendHeaders();
$event->stopPropagation(true);
} elseif($response->getStatusCode() == 500){
//DO SOMETHING else?
return;
}
}
在这段代码中,我们永远不会返回404错误,我们只是将请求的URL作为参数调用路径(在我的示例索引中)
我希望能帮到你。

我不确定我是否遵循了您想要实现的目标,您能否举例说明您的目标?
如果您只是尝试将变量添加到传递的视图模型中,您甚至可以在控制器中执行此操作,请查看 AbstractActionController
/**
* Action called if matched action does not exist
*
* @return array
*/
public function notFoundAction()
{
$response = $this->response;
$event = $this->getEvent();
$routeMatch = $event->getRouteMatch();
$routeMatch->setParam('action', 'not-found');
if ($response instanceof HttpResponse) {
return $this->createHttpNotFoundModel($response);
}
return $this->createConsoleNotFoundModel($response);
}
/**
* Create an HTTP view model representing a "not found" page
*
* @param HttpResponse $response
* @return ViewModel
*/
protected function createHttpNotFoundModel(HttpResponse $response)
{
$response->setStatusCode(404);
// Add in extra stuff from your ServiceLocator here...
// $viewModel->setTemplate(..);
return new ViewModel(array(
'content' => 'Page not found',
));
}

首先是创建视图:
模块/ Yourapplication /视图/ yourapplication /错误/ index.phtml
模块/ Yourapplication /视图/ yourapplication /错误/ 404.phtml
第二件事是在模块config中注册视图:
在你的应用程序的module.config.php中
'view_manager' => array(
//[...]
'not_found_template' => 'error/404',
'exception_template' => 'error/index',
'template_map' => array(
//[...]
'error/404' => __DIR__ . '/../view/yourapplication/error/404.phtml',
'error/index' => __DIR__ . '/../view/yourapplication/error/index.phtml',
),
// [...]
),

在module.php
中,您还可以更改模板和布局。
function onBootstrap(EventInterface $e) {
$app = $e->getApplication();
$evt = $app->getEventManager();
$evt->attach(MvcEvent::EVENT_DISPATCH_ERROR, array($this,'onDispatchError'), 100);
}
function onDispatchError(MvcEvent $e) {
$vm = $e->getViewModel();
$vm->setTemplate('layout/blank');
}

您应首先分离默认的notfoundstrategy并在Module.php中,如果是404,您应该从控制器返回一个新的viewmodel。请参阅此帖子:http://www.cagataygurturk.com/zf2-controller-specific-not-found-page/
