Question

我的网站链接到Paypal。在我的网站上，我将信息传递给PayPal，如下所示;

<form target="paypal" action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">

        <input type="hidden" name="cmd" value="_cart">
        <input type="hidden" name="business" value="youremail@email.com">

            echo "<input type='hidden' name='quantity_1' value='" . $Children . "'>";
        }
        ?>

    </form>

付款后，用户将被重定向回我网站上的“感谢您”页面。在此页面上，我可以在确认电子邮件中使用通过PayPal传递的信息。

        $ItemName1 = $keyarray['item_name1'];
        $ItemName2 = $keyarray['item_name2'];
        $ItemName3 = $keyarray['item_name3'];
        $TotalCost = $keyarray['mc_gross'];
        $Quantity1 = $keyarray['quantity1'];
        $Quantity2 = $keyarray['quantity2'];
        $Quantity3 = $keyarray['quantity3'];
        $ItemCost1 = $keyarray['mc_gross_1'];
        $ItemCost2 = $keyarray['mc_gross_2'];
        $ItemCost3 = $keyarray['mc_gross_3'];
        $Currency = $keyarray['mc_currency'];
        $BookingReference = $keyarray['custom'];
        $FirstName = $keyarray['first_name'];
        $LastName = $keyarray['last_name'];
        $Email = $keyarray['payer_email'];

我已经使用了自定义变量，我相信我只能使用一次 - 这是正确的吗？但是我需要传递另外两个包含离开时间和返回时间的变量 - 如果我不能再次使用自定义变量，我将如何传递这些变量？

Answer 1

将它们与分隔符连接：

// PHP
concatenatedString = "value1:value2:value3";

// HTML
<input type="hidden" name="custom" value="<?php echo concatenatedString ?>"/>

然后当它返回时，您可以拆分值并正确分配它们。
