我正在尝试为联系表单添加其他验证。我需要在表单底部的复选框，用户在提交表单之前检查该复选框。
这是我到目前为止所做的，它验证了表格。我想知道如何添加一个复选框，以便仅在选中该框时才提交表单

将required放在标记复选框上。例如：
<input type="checkbox" name="" value="" required> text

在验证我编码的表单时，我只使用了Recaptcha。这是你的选择吗？如果是，那么您需要该网站上线，以便您可以访问该网站的域名。
要开始此操作，请转到：https://www.google.com/recaptcha/intro/v3beta.html
获得SITEKEY＆amp; SECERTKEY - 他们一步一步（非常简单）了解如何访问这两个密钥。
一旦你在头标签中只有一小段代码，就像这样：
<head>
<script src='https://www.google.com/recaptcha/api.js'></script>
</head>
之后，您只需将代码添加到表单标记中，如下所示：
<form>
<!-- put this wherever you want it in the form - usually at the bottom -->
<div class="g-recaptcha" data-sitekey="<!-- Site Key HERE -->"></div>
</form>
最后，只需在处理表单数据的PHP代码中对其进行授权，例如：
$captcha = $_POST["g-recaptcha-response"]; // Declare variable
if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
if(!$captcha){
header("Location: <!-- Error HTML page OR echo and error statement -->");
exit;
}
$secretKey = "<!-- SECRET KEY HERE -->";
$ip = $_SERVER['REMOTE_ADDR'];
$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secretKey."&response=".$captcha."&remoteip=".$ip);
$responseKeys = json_decode($response, true);
if(intval($responseKeys["success"]) !== 1) {
echo '<h2>Spam Detected</h2>';
}
else {
header("Location: <!-- Thank you HTML page OR echo and thanks statement -->");
}
你会看到我评论了网站和网站的位置。秘密密钥去。
