MysqlのデータをHTML, PHPで表示する（3. Mysqlのデータ書き換え）

Posted at

お疲れ様です。
真冬でもクーラーガンガンのJuesa09です。

さって今回は、前回第2回から新たに以下機能を追加してみました。

  1. 表の状況欄に在庫状況（Y:在庫あり, M:在庫なし）を反映。
  2. ”データベースに登録”ボタンを押すと在庫状況Y（在庫あり）でデータベースに登録し、下表にも反映。
  3. 下表中の”売れた日”欄に売上日を記入して最右の”売上記録”ボタンを押すと、データベース内の在庫状況をMへ書き換え。また、”売れた日”欄のテキストアエリアと”売上記録”ボタンをクローズする。（下画像中ID8のよう）

    コードは以下になります。（データベースのカラムの設定は第2回を見て頂けますと幸いです。）
