こんにちは、私はphpを初めて使用し、追加ボタンが押されたときにテーブル行を動的に追加するフォームを作成しました。データベースに保存でき、ユーザーが編集をクリックしたときに値を保持できますが、私の問題は送信を押します。つまり、更新ボタンを押すと、以前のレコードが削除され、新しく追加された行だけが保存されます。または、変更を加えずに更新ボタンを押すと、動的に追加されたテーブルからすべての値が削除されます。データベースに挿入する前に削除コマンドを書きました以前のレコードをデータベースに削除して新しいレコードを保存する必要がありますが、レコードを削除し、新しく追加された行だけを保存します誰か助けてください。ここで何か間違っているのは、javascript と一緒に私のコードです
