所以，我使用了一个使用HTML，JS和PHP的联系表单给我发了一封电子邮件。我想添加reCaptcha，但还没有想出如何做到这一点。有谁可以帮助我吗？ ：）
该片段包含JS＆amp; HTML，PHP就在其中。
// Contact Form Scripts
$(function() {
$("#contactForm input,#contactForm textarea").jqBootstrapValidation({
preventSubmit: true,
submitError: function($form, event, errors) {
// additional error messages or events
},
submitSuccess: function($form, event) {
event.preventDefault(); // prevent default submit behaviour
// get values from FORM
var name = $("input#name").val();
var email = $("input#email").val();
var phone = $("input#phone").val();
var message = $("textarea#message").val();
var firstName = name; // For Success/Failure Message
// Check for white space in name for Success/Fail message
if (firstName.indexOf(' ') >= 0) {
firstName = name.split(' ').slice(0, -1).join(' ');
}
$.ajax({
url: "/contact_me.php",
type: "POST",

name: name,

// Create the email and send the message
$to = 'email@email.com'; // Add your email address inbetween the '' replacing yourname@yourdomain.com - This is where the form will send a message to.
$email_subject = "Website Contact Form: $name";
$email_body = "You have received a new message from your website contact form.\n\n"."Here are the details:\n\nName: $name\n\nEmail: $email_address\n\nPhone: $phone\n\nMessage:\n$message";

要解决未捕获的ReferenceError：$未定义，请在包含JS文件之前添加<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">。
这应解决 Uncaught ReferenceError：$未定义问题。
修改 当您完成与表单相关的所有操作时。现在第一步是获取reCAPTCHA API密钥。要将reCAPTCHA添加到您的站点，您需要注册您的站点并获取reCAPTCHA API密钥。
您可以通过here在Google上注册您的网站，并获取用于显示reCAPTCHA小部件的网站密钥。在这里，您还可以获得密钥，它有助于授权您的站点与reCAPTCHA服务器之间的通信。
第二步是reCAPTCHA API javaScript库包含。使用下面的代码来包含此reCAPTCHA API JS库。
<script src="https://www.google.com/recaptcha/api.js" async defer></script>
然后第三步是在窗体中使用窗口小部件。您需要在“提交”按钮之前放置一个简单的Google reCAPTCHA小部件<div>。从第一步用您的站点密钥替换data-sitekey属性值的YOURSITEKEY。
<div class="g-recaptcha" data-sitekey="YOURSITEKEY"></div>
最后和第四步是使用您的服务器端代码处理Google reCAPTCHA API授权响应，以使用Google reCAPTCHA验证您的表单。只需将第一步中的YOURESECRETKEY替换为您的实际密码即可。
$errMsg = '';
if(isset($_POST['submit']) && !empty($_POST['submit'])):
//Check google recaptcha reponse...
if(isset($_POST['g-recaptcha-response']) && !empty($_POST['g-recaptcha-response'])):
//your site secret key
$secret = 'YOURESECRETKEY';
//get verify response data
$verifyResponse = file_get_contents('https://www.google.com/recaptcha/api/siteverify?secret='.$secret.'&response='.$_POST['g-recaptcha-response']);
$responseData = json_decode($verifyResponse);
if($responseData->success):
//Success: do code to store your data...
else:
$errMsg = 'Robot verification failed, please try again.';
endif;
else:
$errMsg = 'Please click on the reCAPTCHA box.';
endif;
//If any error...
if(!empty($errMsg)) :
print $errMsg;
return false;
endif;
endif;
