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进行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，但我希望进行表单检查，以确保用户在提交表单之前没有清除字段。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$_GET超全局变量以从查询字符串中获取表单数据，以及使用 echo 从超全局变量中填写表单$_GET而不是用户应该使用的会话数据提交表格而不填写所有内容。其他所有内容都从教程中逐字复制。
任何解决这个问题的帮助，即使它正在重新考虑我可能会如何去做，将不胜感激。
下面是表单页面和处理页面的代码。
表格页面：
