我正在尝试使用查询字符串预先填写表单，并让用户进行任何必要的更改，然后按提交并让表单处理并向管理员发送电子邮件，以执行他们需要对信息执行的任何操作。
我正在使用PHP来填充表单，我从NetTuts的电子邮件表单处理教程开始，因为它进行了内联验证。希望验证不是必需的，因为所有字段都已预先填写，但我想进行表单检查，以确保用户在提交表单之前不会清除字段。我不知道为什么表单无法正确处理。
我的表单和教程之间的唯一变化是变量名称，包含和一些$_GET超全局变量以从查询字符串中获取表单数据，以及使用echo从$_GET超全局变量而不是会话数据中填写表单，如果用户提交表单而不填写所有内容。其他所有内容均已从教程中逐字复制。
任何帮助解决这个问题，即使是重新考虑我如何去做这件事，也将不胜感激。
下面是表单页和处理页的代码。
表单页面：
<?php
session_start();
// site root folder
$root_folder = "/meetingplannersignup";

$FirstName= $_GET['FirstName'];

几个问题：
1. isset($_POST)永远是真实的
在处理页面中，您需要检查：
if( isset($_POST) )
即使$_POST为空，这也将始终计算为true。您应该检查特定字段以尝试并猜测表单是否已提交
2. 你用id而不是name
通过POST发送的表单值是通过它们的name来标识的，而不是通过它们的id来标识的。在 HTML 中，您可以保留 id 属性，但对于要发布的每个字段，您必须添加一个 name 属性：
<input type="text" class="form-control" name="LastName" id="LastName" value="<?php echo $LastName; ?>">
如果仅使用 id 标识窗体控件，则$_POST['LastName']为空。
我没有检查其余的，但您应该先尝试修复这些要点。
