因为我是初学者，我陷入了困境。注意：感谢中存在电子邮件发送代码.php
我的问题是我必须存储所选的日期，并在通过PayPal完成付款后传递到另一个页面。我已经尝试过 php 会话，但没有在我落后的地方。
成功完成交易后，我从PayPal（如txn_id、payer_email等）中以 _POST 美元的价格获取所有详细信息，但我没有得到我在表格中选择的日期。
请帮助我走向正确的方向。
我正在研究PayPal集成，我有 1 个表单，其中存在两个字段（索引.php）
- 选择日期
- 门票数量
代码索引.php ：
<?php
@session_start();
$var_value = $_POST['eventdate'];
$_SESSION['eventdate'] = $var_value;
echo $_SESSION['eventdate'];
?>
<form name="_xclick" action="https://www.sandbox.paypal.com/r" method="post">
<table border="0" cellspacing="0" cellpadding="5" id="tbl_paypal_form">

<td colspan="2"><div id="ticket_amount">£10 per person</div></td>
</tr>
<tr>
<td>Select Event Date <span class="mandatory">*</span></td>
<td><select name="eventdate" id="eventdate" class="form_field">
<option value="">Select Date</option>
<option value="Sat 14 July 2012">Sat 14 July 2012</option>

您应该使用 PayPal 的自定义数据字段来发送和接收有关付款的其他值。只需在表单中添加另一个输入
<input name="custom" type="hidden" value="" />
如果您需要发送两个或更多值，您可以使用像|这样的分隔符连接它们，然后在从PayPal取回它们时处理它们。
编辑
将表单更改为
<form name="_xclick" action="https://www.sandbox.paypal.com/r" method="post" onsubmit="buildCustomVar()">
结束</body>标记之前向页面添加一点 javascript
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
function buildCustomVar()
{
var custom = $('select[name="eventdate"]').val() + "|" + $('input[name="quantity"]').val();
$('input[name="custom"]').val(custom);
}
</script>
在服务器端，只需简单地分解您获得的价值
$temp = explode("|", $_POST['custom']);
$date = $temp[0];
$quantity = $temp[1];
将您的表单移至
<form name="_xclick" action="https://www.sandbox.paypal.com/r" method="post" onsubmit="buildCustomVar()">
添加 JavaScript
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
enter code here
function buildCustomVar()
{
var custom = $('select[name="eventdate"]').val() + "|" + $('input[name="quantity"]').val();
$('input[name="custom"]').val(custom);
}
</script>
