会社からアイテムを受け取ったら、PHPフォームにすべてのアイテムの詳細を入力し、MySQLに保存します
MySQLには2つのテーブルがあり、1つは受信で、2つ目は在庫です
だから私がアイテムを手に入れたとき、そのアイテムは2つのテーブルの受け取りと在庫に保存されます
ただし、在庫(テーブル)アイテムが同じであるため、アイテム名と会社が同じ場合は更新したいので、数量のみが変更されます
しばらくすると、新しいアイテムが正常に保存されます
どうすればこれを行うことができますか この問題を解決するのを手伝ってください ありがとう
mysql_query("INSERT INTO receive SET date='$date',company='$company',itemname='$itemname',quantity='$quantity',category='$category',signature='$signature'");
$result = mysql_query("INSERT INTO stock SET date='$date',company='$company',itemname='$itemname',quantity='$quantity',category='$category',signature='$signature'")
これは私の完全なスクリプトです
