Symfony 3 twig file with render controller - php

Question

I've a problem with Symfony.
I've a VideoController that renders a twig page.
This twig page includes another twig page that has a rendercontroller. With this render controller, the route crash and it says that the "video" variable that I send with the first controller doesn't exists. What's wrong?
This is the code for VideoController:
public function getVideo(Request $request, $id) {
$entityManager = $this->getDoctrine()->getManager();
$video = $entityManager->getRepository('AppBundle:Video')->getVidById($id);
return $this->render('vids/videos.html.twig', ['video' => $video]); //Needs improvements
}
videos.html.twig:
{% block main %}
<center>
<video controls style="width:720px;height:360px;" poster="poster.png">
<source src="{{ video.link }}" type="video/mp4;" codecs="avc1.42E01E, mp4a.40.2" />
</video>
{{ include ("comments/comment.html.twig") }}
</center>
{% endblock %}
comment.html.twig:
{% block comment %}
<br><br>
<center>
{{ render(controller('AppBundle:Video:commentVideo')) }}
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
</center>
{% endblock %}
CommentController:
class CommentsController extends Controller
{
/*
* Check if session is valid. If so, user can comment. SECURITY SYSTEM NEEDS TO BE DEVELOPED!!!
* #Route("/", name="comment")
* #Method({"GET", "POST"})
*/
public function commentVideoAction(Request $request) {
$comment = new Comment();
$form = $this->createFormBuilder($comment)
->add('text', TextType::class)
->add('Invia Commento', SubmitType::class)
->getForm();
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
$comment = $form->getData();
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($comment);
$entityManager->flush();
return $this->render('vids/videos.html.twig');
}
return $this->render('vids/videos.html.twig', array(
'form' => $form->createView(),
));
}
}

Answer 1

In your render (commentVideoAction), you have the twig file "vids/videos.html.twig" and you don't pass the video variable. I think you use the bad template. (

Answer 2

I think there s a mistake in your VideoController.
Try with public function getVideoAction(Request $request, $id) instead of just getVideo
And your structure is bad, you have a loop in your controllers, try like this:
videos.html.twig:
{% block main %}
<center>
<video controls style="width:720px;height:360px;" poster="poster.png">
<source src="{{ video.link }}" type="video/mp4;" codecs="avc1.42E01E, mp4a.40.2" />
</video>
{{ render(controller('AppBundle:Video:commentVideo')) }}
</center>
{% endblock %}
comment.html.twig:
{% block comment %}
<br><br>
<center>
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}
</center>
{% endblock %}
CommentController:
class CommentsController extends Controller
{
/*
* Check if session is valid. If so, user can comment. SECURITY SYSTEM NEEDS TO BE DEVELOPED!!!
* #Route("/", name="comment")
* #Method({"GET", "POST"})
*/
public function commentVideoAction(Request $request) {
$comment = new Comment();
$form = $this->createFormBuilder($comment)
->add('text', TextType::class)
->add('Invia Commento', SubmitType::class)
->getForm();
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()) {
$comment = $form->getData();
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($comment);
$entityManager->flush();
return $this->render('vids/videos.html.twig');
}
return $this->render('vids/comment.html.twig', array(
'form' => $form->createView(),
));
}
}
