PHP 表单按钮不提交；仅页面刷新

Question

此表单最初使用 reCAPTCHA v1，但我已删除了相关代码。 我正在收集用户注册信息以发布到 MySQL 数据库，但提交按钮只会刷新页面，不会进一步导致出现确认电子邮件的消息。这些文件可以访问且有效，但表单本身和提交不起作用。

我尝试包含 reCAPTCHA v2 作为替代品，并成功完成，但表单仍然未提交。我已经把它删除了。此外，我还删除了字段以查看条款和条件的复选框是否是问题所在，因为如果未选中，它不会像其他字段那样抛出错误，但这也不起作用。我已经回顾了之前有关 PHP 表单提交问题的问题，我发现按钮类型不正确，如未提交，但它是正确的类型。数据库已确认连接，这是“config.php”的调用

表单的 PHP 代码:

$data['PageName']='SIGN UP FOR YOUR FREE ACCOUNT TODAY';
$data['PageFile']='signup';
$data['PageTitle'] = 'Sign Up - GPW'; 

include('../config.php');
require_once('recaptchalib.php');

// Get a key from https://www.google.com/recaptcha/admin/create
$publickey = "6Ld3c-YSAAAAAIIdQocSje_bq1a7Sti3QymRM5hw";
$privatekey = "6Ld3c-YSAAAAAJqrQBNAR_Qb40Mh4BveQ_q8bjv0";

# the response from reCAPTCHA
$resp = null;
# the error code from reCAPTCHA, if any
$error = null;
