我一直在為一個學校專案開發一個在線學習網站。在課程內單擊屬于某個部分的課程時，我無法傳遞變數。這個想法是在課程頁面（formation.html.twig）上，有課程摘要，您可以單擊側邊欄選單中的課程。然后它應該顯示一個具有相同選單的頁面，并顯示課程內容以代替課程摘要 (lesson.html.twig)。
我已經更新了控制器，所以 url 變成了：formations/consulter-formationid-sectionid-lessonid
在視圖中，我寫了 {{ path('app_formations_lesson', {'formation':formation.id, 'section': section.id, 'id':lesson.id}) }}
它對 url 作業正常，當我點擊時顯示正確的值，但是頁面重繪 并且不會加載正確的樹枝視圖 (lesson.html.twig)，它加載了我當前正在使用的相同視圖 (formation.html 。枝條）。
編隊控制器：
#[Route('/formations/consulter-{id}', name: 'app_formations_see')]
public function see($id): Response
{
$formation = $this->doctrine->getRepository(Formation::class)->findOneById($id);
$section = $this->doctrine->getRepository(Section::class)->findAll();
$lesson = $this->doctrine->getRepository(Lesson::class)->findAll();
return $this->render('formations/formation.html.twig', [
'formation' => $formation,
'sections' => $section,
'lessons' => $lesson
]);
}
#[Route('/formations/consulter-{formation}-{section}-{id}', name: 'app_formations_lesson')]
public function seeLesson($id): Response
{
$lesson = $this->doctrine->getRepository(Lesson::class)->findOneById($id);
return $this->render('formations/lesson.html.twig', [
'lesson' => $lesson
]);
}
形成.html.twig
{% extends 'base.html.twig' %}
{% block title %}{{ formation.title }}{% endblock %}
{% block content %}
<div class="formationcontainer text-center">
{% block sidebar %}
{% include "./formations/sidebar.html.twig" %}
{% endblock %}
<h1>{{ formation.title }} par {{ formation.user.firstname }} {{ formation.user.lastname }}</h1>
{{ formation.description }}
<hr>
<h2>Sommaire</h2>
<div class="tableau">

{% for section in formation.sections %}
<thead class="table-success">

<tbody>
{% for lesson in section.lessons %}
<tr>
<td>{{ lesson.title }}</td>

{% endfor %}
</tbody>
{% endfor %}
</table>
</div>

課程.html.twig

側邊欄塊

這個問題從何而來？如何顯示正確的視圖？非常感謝！
編輯：我首先交換了控制器中的代碼以匹配 seeLesson 函式。
#[Route('/formations/consulter-{formation}-{section}-{id}', name: 'app_formations_lesson')]
public function seeLesson($id): Response
{
$formation = $this->doctrine->getRepository(Formation::class)->findOneById($id);
$section = $this->doctrine->getRepository(Section::class)->findAll();
$lesson = $this->doctrine->getRepository(Lesson::class)->findOneById($id);
return $this->render('formations/lesson.html.twig', [
'lesson' => $lesson,
'formation' => $formation,
'sections' => $section
]);
}
#[Route('/formations/consulter-{id}', name: 'app_formations_see')]
public function see($id): Response
{
$formation = $this->doctrine->getRepository(Formation::class)->findOneById($id);
$section = $this->doctrine->getRepository(Section::class)->findAll();
$lesson = $this->doctrine->getRepository(Lesson::class)->findAll();
return $this->render('formations/formation.html.twig', [
'formation' => $formation,
'sections' => $section,
'lessons' => $lesson
]);
}
uj5u.com熱心網友回復：
它呈現了錯誤的頁面，因為您的 URL 太相似了。
當試圖確定要執行什么方法時，Symfony 將請求的 URL 與控制器方法上方的路由定義從上到下匹配。
例如，如果您請求/formations/consulter-1-2-3，Symfony 首先嘗試將其與/formations/consulter-{id}. 如果您替換 ，這匹配1-2-3，{id}因此它執行該see方法。
要解決此問題，您有兩種選擇：
在控制器中切換 2 種方法的順序，以便在方法seeLesson上方定義see方法。Symfony 將首先嘗試匹配該seeLesson方法的路由。
或者保持方法順序不變，但是給方法{id}的路由中的引數添加一個約束see，指定匹配的{id}只能由數字組成：
#[Route('/formations/consulter-{id}', name: 'app_formations_see', requirements: ['id' => '\d '])]
