【PHP】Symfonyで画面間を遷移させるための方法

記事作成の背景

ページ遷移の備忘録して残します。

完成イメージ

こんな感じで、ページを遷移させるサンプルです。

↑↓

templates/conference/index.html.twg

{% extends 'base.html.twig' %}

{% block title %}Hello ConferenceController!{% endblock %}

{% block body %}
<style>
    .example-wrapper { margin: 1em auto; max-width: 800px; width: 95%; font: 18px/1.5 sans-serif; }
    .example-wrapper code { background: #F5F5F5; padding: 2px 6px; }
</style>

<div class="example-wrapper">
    <h1>Hello {{ controller_name }}! ✅</h1>

    This friendly message is coming from:
    <ul>
        <li>Your controller at <code><a href="{{ 'C:/Users/pgrfr/Desktop/hellosymfony6/src/Controller/ConferenceController.php'|file_link(0) }}">src/Controller/ConferenceController.php</a></code></li>
        <li>Your template at <code><a href="{{ 'C:/Users/pgrfr/Desktop/hellosymfony6/templates/conference/index.html.twig'|file_link(0) }}">templates/conference/index.html.twig</a></code></li>
    </ul>
    <div>
        {{welcome_name}}
    </div>
    <div>
        <a href="/conference/second">つぎへ</a>
    </div>
</div>
{% endblock %}

templates/conference/second.html.twg

<h1>{{second_page}}</h1>
<h2>
    <a href="/conference">戻る</a>
</h2>

src/Controller/ConferenceController.php

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Doctrine\ORM\EntityManagerInterface;//追加
use App\Entity\Product; // Productエンティティの名前空間を正しく指定

class ConferenceController extends AbstractController
{
    private $entityManager;

    public function __construct(EntityManagerInterface $entityManager){
        $this->entityManager = $entityManager;
    }

    #[Route('/conference', name: 'app_conference')]
    public function index(): Response
    {
        $conferencedata = 'ConferenceController';
        $welcomename = '大谷';

        $id=1;
        $memberlist = $this->entityManager->getRepository(Product::class)->find($id);
        //dd($memberlist->getName());

        $welcomename = $memberlist->getName();

        return $this->render('conference/index.html.twig', [
            'controller_name' => $conferencedata,
            'welcome_name'=>$welcomename
        ]);
    }
    
    #[Route('/conference/second',name:'app_conference_second')]
    public function secondPage():Response
    {
        $secondData = '遷移後のページ';
        return $this->render('conference/second.html.twig', [
            'second_page' => $secondData
        ]);
    }
}

以上です。
こんなかんじでページ遷移させることができました、。
