【问题描述】：
我对 symfony2 有这样的问题。
我有 base.html.twig，这个 base 是其他树枝的模板。 我想渲染控制器，其中包含带有语言环境类型输入字段的表单。 该表格将用于更改网站的语言。
我的语言控制器：
<?php
namespace Soczewki\PlatformaBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class LanguageController extends Controller {
public function createAction(Request $Request)
{
$form = $this->createFormBuilder()
->setMethod('POST')
->setAction(null)
->add('locale', 'locale', array(
'label' => ' ',
'choices' => array('pl' => 'Polski', 'de' => 'Deutsch', 'en' => 'English'),
'data' => $this->getRequest()->getLocale(),
'required' => true))
->add('submit', 'submit')
->getForm();
$form->handleRequest($Request);
if($form->isValid()) {
$this->getRequest()->setLocale('en');
}
return $this->render("SoczewkiPlatformaBundle::myForm.html.twig",
array(
'form' => $form->createView(),
'req' => $r
));
}
}
整个base.html.twig：
<html>
<head>
<title>{% block pageTitle %}{% endblock %}</title>
{#js#}
<script src="{{ asset('bundles/soczewkiplatforma/js/jquery.js') }}"></script>
<script src="{{ asset('bundles/soczewkiplatforma/js/bootstrap.js') }}"></script>
{#/js#}
{% block stylesheets %}
<link href="{{ asset('bundles/soczewkiplatforma/css/bootstrap.min.css') }}" rel="stylesheet">
<link href="{{ asset('bundles/soczewkiplatforma/css/my-style.css') }}" rel="stylesheet">
{% endblock stylesheets %}
</head>
<body>
{% if app.security.getToken().getUser().getAuthKey() is defined %}
{% if app.security.getToken().getUser().getAuthKey() is not empty %}
{% set diff = ( app.security.getToken().getUser().getEndDate()|date('U') - "now"|date('U') ) / 3600 %}
<div style="width: 300px; height: 140px; position: absolute; bottom: 90px; right: 50px;" class="alert alert-danger alert-error">

<strong>Uwaga!</strong> Twoje konto nadal nie zostało aktywowane!<br />

<br /><br />
<a href="{{ url('soczewki_platofrma_account') }}#activate_form_auth_key"><button type="button" class="btn btn-danger">Wpisz kod</button></a>
<button type="button" class="btn btn-default" data-dismiss="alert">Zamknij</button>
</div>
{% endif %}
{% set hasParams = app.request.get('id') %}
{% if hasParams is empty %}
{% set currentPath = url( app.request.attributes.get( '_route', app.request.attributes.get('_route_params'))) %}
{% else %}
{% set currentPath = url( app.request.attributes.get( '_route', app.request.attributes.get('_route_params')),{'id': 0} ) %}
{% endif %}
{% set dirs = currentPath|split('/') %}
{% set flag = "" %}
{% set url = "" %}
<ol class="breadcrumb">
<li><a href="{{ url('soczewki_platofrma_test') }}">Główna</a></li>
{% for key, dir in dirs %}
{% if url is not empty %}
{% set url = url ~ '/' ~ dir %}
{% else %}
{% set url = url ~ dir %}
{% endif %}
{% if flag == true %}
{% if '=' in dir %}
{% set _temp = dir|split('=') %}
{% else %}
{% set _temp = dir|split(' ') %}
{% endif %}
{% if key + 1 == dirs|length %}
<li class="active"> {{ _temp[0]|capitalize|replace('-',' ') }} </li>
{% else %}
<li><a href="{{ url }}"> {{ _temp[0]|capitalize|replace('-',' ') }} </a></li>
{% endif %}
{% endif %}
{% if dir == 'app_dev.php' %}
{% set flag = true %}
{% endif %}
{% endfor %}
<li class="dropdown" style="float: right !important;">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Zalogowano jako: {{ app.security.getToken().getUser().getName() }} <span class="caret"></span></a>
<ul class="dropdown-menu" role="menu">
<li><a href="{{ path('soczewki_platofrma_account') }}">Moje konteło</a></li>
<li><a href="{{ path('logout') }}">Wyloguj</a></li>
</ul>
</li>
</ol>
{% else %}
<ol class="breadcrumb">
<li><a href="{{ url('soczewki_platofrma_test') }}">Główna</a></li>
<!--- logowanie --->
<li class="dropdown" style="float: right !important;">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Zaloguj <span class="caret"></span></a>
<div class="dropdown-menu" style="padding: 15px; padding-bottom: 0px; left: -200px;">
<form action="{{ path('login_check') }}" method="post">
<label for="username">Email/NIP:</label>
<input type="text" id="username" name="_username" />
<br />
<label for="password">Hasełko:</label>
<input type="password" id="password" name="_password" />
<br /><br />
<button type="submit">Loguj do Afganistanu</button>
</form>
</div>
</li>
<!--- log ---->
</ol>
{% endif %}
{{ render(controller('SoczewkiPlatformaBundle:Language:create')) }}
{% block pageContainer %}
{% endblock %}
</body>
</html>
没有任何显示，我也收到任何错误。 为什么会这样？
// 代码更新
myForm.html.twig：
{{ dump(req) }}
{{ form(form) }}
和LocaleListener.php：
<?php
namespace Soczewki\PlatformaBundle\Translations;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;
class LocaleListener implements EventSubscriberInterface
{
private $defaultLocale;
public function __construct($defaultLocale = 'pl')
{
$this->defaultLocale = $defaultLocale;
}
public function onKernelRequest(GetResponseEvent $event)
{
$request = $event->getRequest();
if (!$request->hasPreviousSession()) {
return;
}
// try to see if the locale has been set as a _locale routing parameter
if ($locale = $request->attributes->get('_locale')) {
$request->getSession()->set('_locale', $locale);
} else {
// if no explicit locale has been set on this request, use one from the session
$request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
}
}
public static function getSubscribedEvents()
{
return array(
// must be registered before the default Locale listener
KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
);
}
}
【问题讨论】：
-
你能发布“SoczewkiPlatformaBundle::base.html.twig”吗？为什么要检查 isset($form)？
-
能否贴出base.html.twig文件的代码？
