したがって、同じページではなく別のページに情報を渡す方法を見つけることしかできません。これは完全にクライアント側で行う必要があります。これを使用するとインターネット接続がなくなるため、サーバー側は機能しません。接続が利用可能になったときに送信できるようにフォームデータ。
基本的に、2つのテーブルがあります。1つは左側にあり、ユーザーが必要に応じて変更できる標準の数値セット（フィールドtime1〜time8）があります。これらの値は合計して「designhours」フィールドになります。その数値は、そこで必要なさまざまな計算のために、右側の「designhours」フィールドに入力する必要があります。私の以前の仕事（HTMLやjavascriptではない）では、フィールド名が同じである場合、データが渡されましたが、ここでは明らかにそうではありません。
左側の表を入れる前に、このフォームはうまく機能しましたが、新しい「designhours」値を合計するオプションを追加する必要があります。以前私を助けてくれた人たちに感謝し、今助けてくれた人たちに感謝します。私はまだ学んでいますが、そこに着きつつあります。
ほとんどのフィールドが削除されたサンプルコード。これにより、私が行っていることを確認できます（指摘していただきありがとうございます）完全なコードは以下のとおりです...
したがって、左側の表のフィールド名
time1- time8これらの値は、合計を設計時間に入れるために追加されます
そして右のテーブル
賃金、インストラクター、クラス、designhours （左の表と同じ）、cost、many、atetextfield7、build_cost、buy_cost、build_hours、buy_hours、build_train、buy_train、build_total、buy_total

誰でもできるガイダンスをありがとう。私はこれらすべてに苦労しています。
