私は約1年前に小さな注文フォームのアプリケーションを作成しました。これにより、ユーザーはいくつかのアイテムを選択し、送信ボタンをクリックして送信ボタンをクリックし、phpスクリプトを起動して、注文者と会社の両方の電子メール請求書を作成します。製品を供給します。

今でも私はPHPに非常に慣れていないので、PHPに戻ってきたので、書いた内容をたくさん忘れてしまいました。何らかの理由でメールにエラーが発生し、誰かが見つけてくれることを願っています。

これは私の注文フォームページがどのように見えるかです

ここに画像の説明を入力してください

これはそのページのコードです

私はこれを数日間続けていますが、データベースのphpバージョンなどが原因でこのエラーが発生する可能性があります。

どんな助けでも大歓迎です

更新：これはprint_r（$ _ POST）;から生成されたものです。

Array ( [yourname] => kc 
        [phonenumber] => 987 
        [mobilenumber] => 987

if ($flag = 1)

おそらくif ($flag == 1)

ほとんどの条件文では後者として正しく記述されていますが、マットレストッパーのものではありません。これが、空のマットレストッパーセクションが常に表示される理由です。

表示されている内容に基づく$_POSTと、実際のフォームフィールドの名前とPHPが検出することを期待している名前の間に不一致があるように見えます。たとえば、50/50グースダウンセクションが探しています： $_POST['5050goosedown']しかし、私が想定しているドロップダウンはこれに関連付けられている<select name=". $row['goosedown_id'] .">ため、$_POSTに任意のキーと同じキーで表示され$row['goosedown_id']ます。これらは数値のようです（$_POSTfor1と。の空の値のエントリ2。

なぜ彼らは空ですか？私の推測では、これらのIDは複数のフィールドで共有されているため、同じ名前の複数の選択があり、送信時に互いに競合しています。

選択を次のように変更してみてください（最初の例）：

echo '<td><select name="5050goosedown[' . $row['goosedown_id'] . ']">'
. "<option>1</option>
<option>2</option>
and so on

これにより$_POST、ネストされた配列として表示されます。

array(
    [5050goosedown] => array( 
        [1] => 2, 
        [2] => 
    )
)

ここでの特定のアイテムIDは1と2です。これはPHPコードが期待していることのようです。
