ページの作成

親となるページを選択してください。

ページは必ず何かしらの親ページに紐づきます。
親ページに紐づくページを子ページといいます。
例: 親=スポーツ, 子1=サッカー, 子2=野球

子ページを親ページとして更に子ページを作成することも可能です。
例: 親=サッカー, 子=サッカーのルール

親ページはいつでも変更することが可能なのでとりあえず作ってみましょう!

4. 存在チェック

本稿はLaravelのバリデーションのひとつである存在チェックに関する記事です。

以下の例はtest_tableテーブルのcolAカラムに、パラメータのnameが存在すればOKという実装です。

public function test() {

    $this->validate($request, [
        'name' => 'exists:test_table,colA,
    ]);
    
    ...
    
}
