リクエスト後のレコード表示・遷移の準備

ちょっと、確定申告で、こちらが停滞気味です。

今回のテーマ。長くなりそうなので、数回に分けます。

あまり色んな技術を混ぜないでやった方がいいのではということで、一時的なストレージを使わない方針でやってきましたが、多少後悔しています。
使った方がスッキリできたような……。仕方ありません。このままいきます。

Edit Record のリクエストを出す前に、リクエスト処理後を考えておく必要があります。1レコード編集したら、次のレコードへというユーザの行動は容易に想像つきますよね。
最大30件ですから、Find Records でどんどんやった方がかなり簡単になると思うのですが、これも Find Records はファーストアクセスの1回と決めてしまったので、不採用になります。
本来なら、こういう最大30件と条件が決まっているものは採用してしまった方がいいと思いますが、強行します。

編集機能だけを考えて、リクエスト待ちのページの状態として、

• ファーストアクセスでの表示
• ファーストアクセス以外で1レコード目を含む任意のレコードでの表示

前者は Find Records で取得したデータを使っています。これは、temporary-functions.php の records_find_records() 関数の中で処理しています。
ここで、処理したデータを後者で再利用したいわけです。
　一時的なストレージを使うのであれば、ここで保存するわけです。

それをしないという方針を立ててしまったので、代替案が必要です。
どのレコードを選択しても、レコードのデータが必要なわけですから、取得したデータ丸ごと必要です。

まず、フォームから POST で受け取りたい情報を整理しましょう。

• ファーストアクセス（Edit Record）
  必要なし

• Create Record（レコード新規作成）
  FileMaker 情報ブロックの情報
  このリクエスト処理後の遷移をファーストアクセスと解すれば、以上のみ。
  一連の流れの中にあると解すれば、処理後のレスポンス情報とFileMaker 情報ブロックの情報、直前のページ情報、現在のページ情報

• Edit Record（レコードの編集）但し、ファーストアクセス以外
  レスポンス情報、FileMaker 情報ブロックの情報、現在のページ情報

• Delete Record（）

  というわけで、必要なデータを全部、hidden タイプのフォームコントロールに仕込んでおく方法を採りたいと思います。
  必要な情報は、右の FileMaker 情報ブロックの情報の8項目と Find Records で取得している全レコードの情報です。
  FileMaker 情報ブロックの8項目は、そのまま埋め込み、Find Records の取得済みレコード情報は JSON 化して、response-data として埋め込みます。

必要な変更を加えましょう。まず、JSON に追加する hidden タイプのフォームコントロールを追加します。

今更ですが、キーの命名は、以下で書いています。

• id → camelCase
• レコードのフィールドデータの name → snake_case
• それ以外の HTML 属性 → kebab-case

次に、用意したフォームコントロールのデータを用意するわけですが、最後の response-data の生成用に関数を追加します。

php-functions.php に追加

function mb_left(string $str, int $length, string $encoding = "UTF-8"): string
{
    return mb_substr($str, 0, $length, "UTF-8");
}

データ作成は、Find Records のリクエスト処理後に作るので、temporary-functions.php の records-find-records() 関数を変更します。

temporary-functions.php の records-find-records() 関数

function records_find_records( ): void
{

    global $fmda, $response, $bearer_session_token, $database, $layout, $request_body;

        // セッション有効なら、行いたいリクエスト実行
    
        // レコードの検索
        $response   = $fmda->findRecords($database, $layout, $bearer_session_token, $request_body);

　preferences.php の66行目 $response_field_data = []; の下にフォームコントロールへ埋め混むFileMaker 情報用の変数を設定しておきます。

preferences.php へ追加

$data_info_database = '';
$data_info_layout = '';
$data_info_table = '';
$data_info_record_id = '';
$data_info_mod_id = '';
$data_info_total_record_count = '';
$data_info_found_count = '';
$data_info_returned_count = '';

hidden フォームコントロールに対応するため、bs-builder-class.php の CreateForm() メソッドを変更します。

うまくいきました。JSON のダブルクォーテーションは、HTML エンティティの " を使っています。これ JavaScript を使うとシングルクォーテーションでもうまくいくはずですが、このようなJSONストリングを、シングルクォーテーションを使って、json_decode() を使ってもうまくいきません。submit 後のデータは、次のような状態で、$_POST['response-data'] に入ってきます。

JSON 配列形式になっていますね。これを json_decode() することで、 PHP 配列に変換できます。

　このデータを、セッション中持ち続ければいいわけです。しかし、繰り返しになりますが、これでは、常に、response-data を常に持ち続けないといけないわけですから、迂遠な方法だと思います。
リクエスト自体を PHP ではなく、JavaScript にした方が、スッキリ書けると思います。

　今回、積み残しているのは、

• submit ボタンを押した後の処理
• フッタリンクで response-data を渡す処理

　以上になります。
