参考ブログではLaradockを使っていますが、このブログではLaravelのみで行います。
Laravelをインストールする
モデルクラスの作成
お問い合わせ用のモデルクラスを作成します
|
1 |
php artisan make:model Models/Contact |
app/Models/Contact.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<?php namespace App; use Illuminate\Database\Eloquent\Model; class Contact extends Model { protected $fillable = [//モデルが受け取るデータのフィルター 'name', 'email', 'message', ]; } |
コントローラークラスの作成
お問い合わせ用のコントローラクラスを作成します
|
1 |
php artisan make:controller ContactController |
app/Http/Controllers/ContactController.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
<?php namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Contact; class ContactController extends Controller { public function form() { return view('form'); } public function confirm(Request $request) { $contact = new Contact($request->all()); return view('confirm', compact('contact')); } public function process(Request $request) { return view('complete'); } } |
ルーティングの設定
routes/web.php
|
1 2 3 |
Route::get('/contact', 'ContactController@form'); Route::post('/contact/confirm', 'ContactController@confirm'); Route::post('/contact/process', 'ContactController@process'); |
ビューの作成
お問い合わせ用のビューを作成します。
resources/viewsにhoge.blade.phpを作成していく
resources/views/form.blade.php（入力画面）
|
1 2 3 4 5 6 7 8 |
<input type="text" name="name"> <input type="text" name="email"> <textarea name="message"></textarea> <input type="submit" value="Confirm"> </form> |
resources/views/confirm.blade.php（確認画面）
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
<form action="{{action('ContactController@process')}}" method="post"> {{$contact->name}} {{$contact->email}} {{$contact->message}} <input type="submit" value="Submit"> @foreach($contact->getAttributes() as $key => $value) <input type="hidden" name="{{$key}}" value="{{$value}}"> @endforeach </form> |
resources/views/complete.blade.php（完了画面）
|
1 |
Complete |
サーバーを起動してみる
|
1 |
php artisan serve |
入力画面を表示する
http://127.0.0.1:8000/contact
名前入力、メール入力、テキスト入力、ボタンが表示される
バリデーションの実装
Laravelではバリデーション機能が簡単に実装できます。
app/Http/Controllers/ContactController.php
|
1 2 3 4 5 6 7 8 9 10 11 12 |
public function confirm(Request $request) { $this->validate($request, [ 'name' => 'required', 'email' => 'required|email', 'message' => 'present', ]); $contact = new Contact($request->all()); return view('confirm', compact('contact')); } |
エラーメッセージは $errorsを使用
resources/views/form.blade.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
@if ($errors->any()) <ul> @foreach ($errors->all() as $error) <li>{{ $error }}</li> @endforeach </ul> @endif <form action="{{action('ContactController@confirm')}}" method="post"> {{csrf_field()}} <input type="text" name="name" value="{{old('name')}}"> <input type="text" name="email" value="{{old('email')}}"> <textarea name="message">{{old('message')}}</textarea> <input type="submit" value="Confirm"> </form> |
「入力画面」にもどるボタンを作成する
|
1 2 3 |
<input type="submit" name="action" value="back"> <input type="submit" name="action" value="submit"> |
app/Http/Controllers/ContactController.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
public function process(Request $request) { // ※要バリデーション $action = $request->get('action', 'back'); // 二つ目は初期値です。 $input = $request->except('action'); // そして、入力内容からは取り除いておきます。 if($action === 'submit') { // メール送信処理などを実装 return view('complete'); } else { // 戻る return redirect()->action('ContactController@form') ->withInput($input); } } |
バリデーションの種類を確認する
resources/lang/en/validation.php
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 |
