如何在字段之间添加<br/>

问题描述 投票：0回答：1

我是 Symfony 的新手。 我成功构建了一个表单，但表单字段之间没有空格。 我的表单已显示，但我想在字段之间添加
标签，例如以获得最佳的表单显示效果。 你能告诉我如何实现这一目标吗？

这是我的文件

CategoriesController.php


namespace App\Controller;

...

class CategoriesController extends AbstractController
{
    /**
     * @Route("/categoriesAncien", name="categories")
     */
    public function index(): Response
    {
            $categories = $this->getDoctrine()->getRepository(Categories::class)->findAll();

        return $this->render('categories/categories.html.twig', [
            "form_title" => "Ajouter une catégorie",
            "categories" => $categories,
        ]);
    }

    
    /**
     * @Route("/categories/add", name="add-categorie")
     */
    public function addCategorie(Request $request): Response
    {
        $categorie = new Categories();
        $form = $this->createForm(CategorieFormType::class, $categorie);
        $form->handleRequest($request);
        $nom = $categorie->getNomCategorie();
        $commentaire = $categorie->getCommentaire();

        if($form->isSubmitted() && $form->isValid())
        {
            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->persist($categorie);
            $entityManager->flush();

            return $this->redirect('/categories');
        }

        return $this->render("categories/categorie-form.html.twig", [
            'form_title' => "Ajouter une catégorie",

使用CSS：

这只是我推荐的替代解决方案，但请尝试在表单上添加 CSS 来创建空格。

例如

margin

使用 HTML：

或者，如果不在行之间放置 

<br>
标签，请以这种方式格式化您的分支以创建字段：

{{form_row (form.publicationTime)}}
<br>
{{form_row (form.origin)}}
<br>
{{form_row (form.commission)}}

所以你可以在每行之间放置一个

<br>
（即使我不推荐这种方法）
