大约一年前，我写了一个小订单应用程序，它允许用户选择一些项目，然后单击提交按钮，提交按钮然后触发一个 php 脚本，该脚本为订购它的人和公司创建电子邮件发票供应产品。

现在我对 PHP 还是很陌生，现在我又回到了它，我忘记了很多我写的东西，出于某种原因，我在电子邮件中收到了一个错误，我希望有人能帮助我找到它。

这是我的订单页面的样子

在此处输入图像描述

这是该页面的代码

**End of message**

我已经在这几天了，我很困惑，也许这个错误是由数据库上的 php 版本引起的还是什么？？？

任何帮助将不胜感激

更新：这是从print_r($_POST);

Array ( [yourname] => kc 
        [phonenumber] => 987 
        [mobilenumber] => 987 
        [email] => test@gmail.com 
        [deliveryaddress] => testing 66 
        [1] => 
        [2] => 
        [comments] => sdsdf 
        [code] => MYCODE )

更新 2：电子邮件输出不输出价格以及其他几个值

if ($flag = 1)

应该是if ($flag == 1)

对于大多数条件句，它被正确地写为后者，但不是床垫罩子。这就是为什么总是出现空床垫罩部分的原因。

根据显示的$_POST内容，您的实际表单字段的名称与您的 PHP 期望找到的名称之间似乎存在不匹配。例如 50/50 Goosedown 部分正在寻找： $_POST['5050goosedown']但我认为与此相关的下拉列表是这样的<select name=". $row['goosedown_id'] .">，因此它会显示在 $_POST 中，其键等于任何$row['goosedown_id']值。看起来这些是数字（$_POSTfor1和2.

为什么它们是空的？我的猜测是这些 ID 在多个字段中共享，因此您有多个具有相同名称的选择，并且在提交时它们相互冲突。

尝试将选择更改为如下所示（第一个示例）：

echo '<td><select name="5050goosedown[' . $row['goosedown_id'] . ']">'
. "<option>1</option>
<option>2</option>
and so on

这将导致它显示$_POST为嵌套数组，例如

array(
    [5050goosedown] => array( 
        [1] => 2, 
        [2] => 
    )
)

此处的特定项目 ID 为 1 和 2。这似乎是 PHP 代码所期望的。
