symfony 分页器 + 过滤器表单

Question

我是 Symfony 的新手，我有一个页面，其中有一个文章列表，我在上面创建了一个表单，允许我过滤我的查询结果：

表单工作正常，但是当我单击分页器 table 的第 2 页时，表单重置，所以我的过滤器也重置了。我想要的是我们可以过滤结果并能够使用相同的过滤器对 table 进行分页，并且表单保留他的数据。

这是我现在的代码：

控制器：

public function listeAction(Request $request, $page) {
        if ($page < 1 && strlen($page) != 0) {
            throw new NotFoundHttpException('Page "' . $page . '" inexistante.');
        } else if (strlen($page) == 0) {
            $page = 1;
        }

        $nbPerPage = 5;

        $form = $this->createForm(ArticleRechercheType::class);
        $form->setData(array('rds' => true));

        //if we use filters
        if ($request->isMethod('POST') && $form->handleRequest($request)->isValid()) {
            $data = $form->getData();
            $form = $this->createForm(ArticleRechercheType::class, $data);
            if ($data['famille'] != null) {
                $data['famille'] = $data['famille']->getId();
            }
            $listArticles = $this->getDoctrine()
                    ->getManager()
                    ->getRepository('GRBackOfficeBundle:Article')
                    ->getFilteredArticles($page, $nbPerPage, $data);
        } else {
            $data = $form->getData();
            $form = $this->createForm(ArticleRechercheType::class, $data);

            $listArticles = $this->getDoctrine()
                    ->getManager()
                    ->getRepository('GRBackOfficeBundle:Article')
                    ->getArticles($page, $nbPerPage);
        }

        $nbPages = ceil(count($listArticles) / $nbPerPage);

        if ($nbPages != 0 && $page > $nbPages) {
            throw new NotFoundHttpException('Page "' . $page . '" inexistante.');
        }

        if ($nbPages == 0) {
            $nbPages = 1;
        }

        return $this->render('GRBackOfficeBundle:Article:liste_articles.html.twig', array(
                    'form' => $form->createView(),
                    'listArticles' => $listArticles,
                    'nbPages' => $nbPages,
                    'page' => $page
        ));
    }

表格：

class ArticleRechercheType extends AbstractType {

    public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder->add('famille', EntityType::class, array(
                    'class' => 'GRBackOfficeBundle:Famille',
                    'choice_label' => 'nom',
                    'required' => false
                ))
                ->add('rds', CheckboxType::class, array('required' => false))
                ->add('recherche', TextType::class, array('required' => false))
                ->add('Rechercher', SubmitType::class);
    }

    public function configureOptions(OptionsResolver $resolver) {
        $resolver->setDefaults(array(
            'translation_domain' => false
        ));
    }

}

您可以使用捆绑包（例如 knp paginator 捆绑包），或将您的参数放入会话中。但是这个包会让它变得简单，因为它为你做了一切，你只需要传递你的数据
