php - 基于用户状态的两种不同的 Paypal 表单

Question

我创建了一个网站，其中包含筹款活动的注册表。它具有简单的字段，例如“名字、姓氏、电子邮件等”。在他们点击第一页上的“提交”后，他们会被带到另一个页面，在那里他们可以通过 Paypal 付款。

我已经知道如何在显示“立即购买”的地方插入 Paypal 功能。但是，就我而言，我想要 2 种不同的 Paypal 表格：

如果用户已经注册了另一个特定的会议，他们支付 10 美元（我已经通过 phpmyadmin 在数据库表中获得了注册与会者的列表）
如果用户没有注册大会，他们需要支付 15 美元

如何对其进行编码，以便我可以验证用户是否在已注册与会者的数据库表中并获得 10 美元的费率？（也许我可以通过表格上使用的电子邮件地址进行验证）

这就是我现在为我的 php 文件所拥有的（默认为非与会者的 15 美元常规费率）

你真正需要做的就是改变价格，所以在

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

接下来查询名称列表：

<?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'>";}

?>

当然，您必须检索发布数据并将其设置为 $userinputted。我希望这会有所帮助，如果需要，请向我询问更多详细信息。
