Heyho、jQuery PHPは3つのパラメータでのみ動作します
私は次のコードに問題があります。私はこの例をhttp://phpflow.com/php/how-to-add-edit-and-delete-a-row-in-jquery-flexigrid-using-php-and-mysql/から取り出し、「年齢」オプションだけを削除しました。 削除後、私はもはやフォームを介してデータベースにレコードを追加できなくなりました。手動でレコードを追加すると（phpMyAdminで）、私はウェブページからレコードを編集することができます。
間違いがどこにあるかもしれない誰かが把握でき...
これは私のコードです：

またconnection.phpですが、私のデータベースへの接続が機能します。 私はresponse.phpが3つのパラメータ（名前、給料、年齢）を期待していると思いますが、2つしか得られません... 詳細を尋ねるのをためらってください！
