我目前正在创建联系表单，该表单需要填写验证码以减少垃圾邮件，我遵循了有关如何在代码中使用验证码的教程，但是每次都不起作用时，希望有人可以在此提供帮助。 任何帮助，将不胜感激。

<h1>Contact Us</h1>
<?php if(isset($_GET['CaptchaPass'])){ ?>
<h3>Your message was sent, you should recieve an email back within 24
hours.</h3>
<?php } ?>
<?php if(isset($_GET['CaptchaFail'])){ ?>
<h3>Captcha Failed. Please try again!</h3>

PHP
$firstname = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$message = $_POST['message'];
if(isset($_POST['login'])) {
$url = 'https://www.google.com/recaptcha/api/siteverify';
$privatekey = "Want to keep this private :)";
$response = file_get_contents($url."?
secret".$privatekey."&response=".$_POST['g-recaptcha-
response']."&remoteip".$_SERVER['REMOTE_ADDR']);
$data = json_decode($response);
if(isset($data->success) AND $data->success==true) {
echo("Pass");
}else {
header('Location: contact.php?CaptchaFail=true');
echo("Fail");
}
}

您还可以在表单提交之前使用JavaScript进行Google验证码验证。
var v = grecaptcha.getResponse();
if(v.length == 0){
document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
error = false;
}else{
document.getElementById('captcha').innerHTML="";
}
if(error !== false){
$('#yourformid').submit();
}
return false;

我相信这条线有问题：
if(isset($data->success) AND $data->success==true)
它应该是：
if(isset($data->success) AND $data->success===true)
除此之外，我建议使用Google Composer库（ https://github.com/google/recaptcha ）来验证Recaptcha。 它将解决您的代码行和头疼问题，因为它们将使它们保持最新。
谷歌验证码不起作用
