最近、Laravel 5.1にハマっています。
Laravelは現在、最も注目されているPHPのフレームワークだと思います。
詳しくは、こちらで調べてみました。

LaravelのBladeテンプレートFormのセレクトボックスで出てきたエラー
Laravelでは、ビュー(UI)の部分はbladeというテンプレートエンジンを使います。
以下のように、Formのselectを使って、セレクトボックスを作ってみました。
|
1 2 3 4 |
<div class="form-group"> {!! Form::label('tag_list', 'Tags:') !!} {!! Form::select('tag_list[]', $tags, null, ['class' => 'form-control', 'multiple']) !!} </div> |
するとどうでしょうか？
こんなエラーが出ました。

うーん。。
Laravelは、便利なんですが、日本におけるユーザー人口が少ないために、まだ解説書が少ないです。
LaravelをIDE、統合開発環境で使うには
有償版ですが、PhpStormが最も優れたPHPのIDEです。
以下の画面の通り設定すると、PhpStormでLaravel 5.1が使えるようになります。
無償版なら、NetBeansが良いです。PhpStormよりは少し性能が劣りますが、十分使えます。
Laravelの便利な日本語解説書、WEBサイト
現時点では、以下の本が唯一でかつ、もっとも適した日本語の解説書です。

また、以下のサイトが最も優れたLaravelの学習サイトだと思います。
