php - ユーザーのステータスに基づく 2 つの異なる Paypal フォーム

Question

募金イベントの登録フォームがある Web サイトを作成しました。最初のページで「送信」をクリックすると、別のページに移動し、Paypal で支払うことができます。

「今すぐ購入」と表示されている場所に Paypal 機能を挿入する方法は既に知っています。ただし、私の場合、2 つの異なる Paypal フォームが必要です。

ユーザーが別の特定の会議に既に登録している場合、10 ドルを支払います (既に phpmyadmin を介してデータベーステーブルに登録済み出席者のリストを持っています)。
ユーザーが総大会に登録していない場合、$15 を支払います。

ユーザーが登録済み出席者のデータベーステーブルに存在し、10 ドルのレートを取得しているかどうかを検証できるようにするには、どのようにコーディングすればよいでしょうか? (おそらく、フォームで使用されているメールアドレスで検証できます)

これは、私のphpファイル用に現在持っているものです（参加者以外の場合、デフォルトで15ドルの通常料金に設定されています）

ここで本当に必要なのは、価格を変更することだけです。

<input type="hidden" name="amount" value="15.00">

次に、名前のリストを照会します。

<?php
require_once{'config.php');

$query="SELECT * FROM usertable";
$result=mysql_query($query) or exit("Sql Error".mysql_error());
$num_results = mysql_num_rows($result)-1; 

$in=0;
for ($i=0; $i<=$num_results;$i++){
$userindb=mysql_result($result,$i,"usernamecolumn");
if ($userindb==$userinputted){
echo "<input type='hidden' name='amount' value='10.00'>";
$in=1;
exit;
}
}
if ($in==0){
echo "<input type='hidden' name='amount' value='15.00'>";}

?>

もちろん、投稿データを取得して $userinputted に設定する必要があります。これがお役に立てば幸いです。必要に応じて、詳細についてお問い合わせください。
