https://developers.google.com/recaptcha/docs/verify

if(isset($_POST['submit'])){
$recaptchaResponse = $_POST['g-recaptcha-response'];
$secretKey = 'MYKEY';
$request = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secretKey."&response=".$recaptchaResponse);

    if(!strstr($request,"false")){
echo '<div class="notification error clearfix"><p><strong>Attention!</strong> You didnt complete the captcha.</p></div>';
exit();

然后其余的php文件邮寄表单,但即使你没有完成recaptcha它也只是发送.基本上,如果JSON返回false,我希望它不会发送并显示错误

如果它有帮助,这里也是页面的形式,我也可能在那里做错了...
