How Can I specified the object of my precedent form? - php

Question

In my project I want to use the object created by my precedent form:
Here is the schema of my database:
My QuizController
public function creation(Request $request){
$quiz = new Quiz();
$user = $this->getUser();
$formQuiz = $this->createForm(QuizType::class, $quiz);
$formQuiz->handleRequest($request);
if ($formQuiz->isSubmitted() && $formQuiz->isValid() ) {
$quiz->setCreatedAt(new DateTimeImmutable());
$quiz->setCreatedBy($user);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($quiz);
$entityManager->flush();
return $this->redirectToRoute('creation_questions');
}
return $this->render('quiz/creation.html.twig', [
'formQuiz' => $formQuiz->createView(),
]);
}
And my QuestionController that must be connected with the quiz form
public function creation_questions(Request $request){
$quiz = ?
$question = new Questions();
$formQuestions = $this->createForm(QuestionType::class, $question);
$formQuestions->handleRequest($request);
if ($formQuestions->isSubmitted() && $formQuestions->isValid() ) {
$question->setCreatedAt(new DateTimeImmutable());
$question->setQuiz($quiz);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($question);
$entityManager->flush();
return $this->redirectToRoute('home');
}
return $this->render('questions/questions.html.twig', [
'formQuestion' => $formQuestions->createView()
]);
}
What do I have to write in place of the '?'?

Answer 1

You don't show your routing but you could use paramConverte "magic" from SensioFrameworkExtraBundle and do something like this.
/**
* #Route("/some-route/{id}", name="some_route_name")
*/
public function creation_questions(Request $request, Quiz $quiz)
{
$question = new Questions();
$formQuestions = $this->createForm(QuestionType::class, $question);
$formQuestions->handleRequest($request);
if ($formQuestions->isSubmitted() && $formQuestions->isValid()) {
$question->setCreatedAt(new DateTimeImmutable());
$question->setQuiz($quiz);
$entityManager = $this->getDoctrine()->getManager();
$entityManager->persist($question);
$entityManager->flush();
return $this->redirectToRoute('home');
}
return $this->render('questions/questions.html.twig', [
'formQuestion' => $formQuestions->createView()
]);
}
Where the {id} part of /someRoute/{id} is the Quiz Id. Symfony should automagically fetch the Quiz matching that id. Or you can be more explicit about how the param converter should interpret such a value. More info here https://symfony.com/bundles/SensioFrameworkExtraBundle/current/annotations/converters.html
Alternatively, you could pass the quiz id and fetch the quiz manually (less magic but totally legit).
/**
* #Route("/some-route/{id}", name="some_route_name")
*/
public function creation_questions(Request $request, int $id)
{
$entityManager = $this->getDoctrine()->getManager();
$quiz = $entityManager->getRepository(Quiz::class)->find($id);
$question = new Questions();
$formQuestions = $this->createForm(QuestionType::class, $question);
$formQuestions->handleRequest($request);
if ($formQuestions->isSubmitted() && $formQuestions->isValid()) {
$question->setCreatedAt(new DateTimeImmutable());
$question->setQuiz($quiz);
$entityManager->persist($question);
$entityManager->flush();
return $this->redirectToRoute('home');
}
return $this->render('questions/questions.html.twig', [
'formQuestion' => $formQuestions->createView()
]);
}
