我正在構建一個symfony 3項目,我試圖在提交表單以通知用戶表單已成功提交但它不適用於我的情況下在樹枝模板中顯示一個flashbag消息! 這裏是控制器:symfony flashBag消息不起作用
<?php
namespace EvalBundle\Controller;
use EvalBundle\Entity\SessionEvaluation;
use EvalBundle\Form\SessionEvaluationType;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
class EvaluationController extends Controller
{
/**
* @Route("/evaluation", name="evaluation_session")
* @Method({"GET", "POST"})
*/
public function indexAction(Request $request)
{
$sessioneval = new SessionEvaluation();
$form = $this->createForm(SessionEvaluationType::class, $sessioneval);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()){
$em = $this->getDoctrine()->getManager();
$em->persist($sessioneval);
$em->flush();
$this->get('session')->getFlashBag()->add('notice', 'la session est lancée avec succes');
unset($entity);
}
return $this->render('@Eval/Default/Evaluation/newEvaluationSession.html.twig',array(
'form' => $form->createView()
));
}
}
這裏是樹枝模板:
{% extends ':default:superAdminBase.html.twig' %}
{% block menu %}
{% include(':default:menu.html.twig') %}
{% endblock %}
{% block header %}
{% endblock %}
{% block body %}
<div class="row">
<div class="col-lg-12 col-md-12 col-sm-12">
<h1 class="page-header">
Lancer une nouvelle session d'évaluation
</h1>
</div>
</div>
{% set flashbag_notices = app.session.flashBag('notice') %}
{% if flashbag_notices is not empty %}
<div class="row">
<div class="col-lg-6">
<ul>
{% for notice in flashbag_notices %}
{{ dump(flashbag_notices) }}
<li>{{ notice }}</li>
{% endfor %}
</ul>
</div>
</div>
{% endif %}
<div class="row">
<div class="col-md-12">
<div class="panel panel-default">
<div class="panel-heading">
Session d'évaluation des Compétences
</div>
<div class="panel-body">
<div class="row">
<div class="container">
<div class="col-lg-12 ">
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
</div>
</div>
</div>
</div>
</div>
</div>
</div>
{% endblock %}
{% block javascript %}
{% endblock %}
我已經試過了,但DOC我不知道它不工作在我的身邊。
請幫忙!感謝
