我正在使用以下内容将表单发送到电子邮件地址。我想合并验证码，但想稍微调整一下。
1）如果未填写验证码，我希望错误作为警报框弹出。
2）如果验证码填写正确，那么它应该重新加载显示感谢消息的页面（位于下面脚本的底部）。
3）与其检查验证.php文件，我希望它在此页面上检查它。（我用指向 verify.php 文件的链接替换了操作中的永久链接 - 我不想这样做！

这是我的验证.php文件中：

表单更改
<form class="form" method="POST" action="index.php" onsubmit="return validateCaptcha()">
<input type="hidden" name="valid" value="0" />
在表单下方
<script type="text/javascript">
