【问题描述】:
下面是我的 IPN 代码。我的问题是我无法在表payments_paypal 中添加多个项目名称或数量。事实上 IPN 没有监听 payer_id,quantity,item_name(multiple items)。
我们如何在这里 $_POST item_name1 或 item_name2 等,以便在验证时我可以在其他页面中获取它,这将是成功页面。虽然我已经通过其他方法实现了这一点,但这不是正确的方法。所以我想知道为什么这些变量不是以字符串的形式来自 ipn,只有这些变量以字符串 txn、smt、st、currency 的形式出现,其余的都丢失了。如果我们必须在这里使用循环,我们如何发送值以从这里 ipn.php 插入循环。
任何帮助将不胜感激。
