⑨ Laravelで簡単なCRUDシステムを作る（Update…データを更新する）

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\TodoController;

// Route::get('/', function () {
//     return view('welcome');
// });

Route::get('todo/index', [TodoController::class, 'index'])->name('todo.index');
Route::get('todo/create', [TodoController::class, 'create'])->name('todo.create');
Route::post('todo/store', [TodoController::class, 'store'])->name('todo.store');
Route::get('todo/show/{id}', [TodoController::class, 'show'])->name('todo.show');
Route::get('todo/edit/{id}', [TodoController::class, 'edit'])->name('todo.edit');
Route::post('todo/update/{id}', [TodoController::class, 'update'])->name('todo.update'); //追記

    public function update(Request $request, $id)
    {
      $todo = Todo::find($id);
        $todo->content = $request->input('content');
        $todo->done = $request->input('done');

      $todo->save(); 
      return redirect('todo/index'); 
    }

<div class="container-sm">
  <link href="{{ asset('css/app.css') }}" rel="stylesheet">
  <h1>editです</h1>
  <form method="POST" action="{{ route('todo.update', ['id' => $todo->id] ) }}"> //formの送信先を追記
  @csrf
  ID：{{ $todo->id }} <br>
  内容：<input type="text" name="content" value="{{ $todo->content }}">  <br>
  対応したかどうか：<input type="text" name="done" value="{{ $todo->done }}"> <br>
  作成日時：{{ $todo->created_at }} <br>
  更新日時：{{ $todo->udpated_at }} <br>

  <input type="submit" value="更新する" class="btn btn-info">
  </form>
</div>
