Laravelのユーザー登録フォームに、都道府県を選択するためのセレクトボックスを追加したい

こんにちは。

Laravelのユーザー登録フォームに、都道府県を選択するためのセレクトボックスを追加したいです。

都道府県の各id(1~47)がDBに保存されるようにしたいです。以下のページを参考にコードを書いてみました。しかし、フォームは表示されユーザー登録もできるものの、DBを確認すると、都道府県のidは登録されない状況です。

以下がコードになります。

Register.blade.php

php
1@extends('layouts.app')

3@section('content')
4<div class="container">
5    <div class="row justify-content-center">
6        <div class="col-md-8">
7            <div class="card">
8                <div class="card-header">{{ __('Register') }}</div>
9
10                <div class="card-body">
11                    <form method="POST" action="{{ route('register') }}">
