我有一个问题，我试图做一个收据类型的页面，将显示购买的项目，总价，数量和东西。所有这些都有用。直到我需要添加交付选项和付款选项。
在我可以成功地从单选按钮输入数据到我的数据库之前，但现在我只需要先显示它们，然后才能在数据库中输入它们。
这是我的billing.php页面，用户将选择他/她的交付选项和支付选项。

正如你所看到的，我试图在底部回显$载体，但我得到这个身份不明的索引错误，我尝试使用$_SESSION和$_REQUEST。但我似乎不能让它出现。
对不起，如果这是一个很长的问题，我只是有麻烦与我的项目。
删掉这两行:
$carrier=$_SESSION['carrier'];
$payment=$_SESSION['payment'];
您已经在之前的$_REQUEST中设置了变量。您从未将它们复制到会话中，因此不需要在这里重新分配变量。
