ひどく間違っているのは次のとおりです。

最初のドロップダウンで何かを選択して送信すると、すべて問題ありません...

しかし、サイズを追加すると、次のエラーが発生します。

致命的なエラー: 62 行目の /website.com/class/banden.class.php の非オブジェクトに対するメンバー関数 bindParam() の呼び出し

62 行目 =$stmt->bindParam(":size", $size, PDO::PARAM_STR);

私の選択に依存します...時々それはこの行です：

$stmt->bindParam(":type", $type, PDO::PARAM_INT);

誰か助けてくれませんか？私は自分でそれを修正しているとは思わない:(

どうもありがとうございます
