任何帮助都会因我遇到的表单问题而受到赞赏。我在这里搜索无济于事，无论如何可能无法正确搜索。我在phphelp.com上发布但没有成功。
基本上我有一个页面有一个下拉列表，用户可以选择1,2,3，... 10,20，... 500,1000或'其他'。选择除其他之外的任何东西都不会返那就是问题所在。选择“其他”将打开一个文本字段，用户可在其中手动输入数字。此选项有效，并返回正确的值以及电子邮件中的行信息。
由于长度限制，我无法发布整个代码，但您可以点击此处： http://www.phphelp.com/forum/beginners-learning-php/form-problem
这是html（剥离）：
<?php
//phpinfo();
//Start session
session_start();
//unset($_SESSION['SESS_MEMBER_ID']);
//Check whether the session variable SESS_MEMBER_ID is present or not
//echo $_SESSION['SESS_MEMBER_ID'];
if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) {
header("location: ../Login.html");
exit();
}
?>

您的表单中有重复的字段名称。
例如，查看112-24 CCC-241焦炭可乐经典罐24 / 355ml cs。
确保您具有唯一的名称，否则您将使用空或隐藏字段覆盖值。
另外：如果您选择较短的字段名称（最好没有空格！），它将简化您的生活。
