标签: php html captcha

我目前正在创建一个联系表单,表单需要填写验证码以减少垃圾邮件,我已经按照如何在我的代码中使用验证码的教程,但每次它不工作时,希望有人可以在这里提供帮助。任何帮助将不胜感激。

HTML

 <body>
 <hgroup>
 <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 } ?>
 </hgroup>
 <form method='post' action='contactver.php'>
 <div class="group">
 <input type="text" name="name"><span class="highlight"></span><span 
 class="bar"></span>
 <label>Name</label>
 </div>
 <div class="group">
 <input type="email" name="email"><span class="highlight"></span><span 
 class="bar"></span>
 <label>Email</label>
 </div>
 <div class="group">
 <input type="phone" name="phone"><span class="highlight"></span><span 
 class="bar"></span>
 <label>Phone No.</label>
 </div>
 <div class="group">
 <input type="message" name="message"><span class="highlight"></span><span 
 class="bar"></span>
 <label>Message</label>
 </div>
<div class="g-recaptcha" data-
sitekey="My Key, want to keep private :)"></div>
<button type="submit" name="login" class="button buttonBlue">Submit Message
<div class="ripples buttonRipples"><span class="ripplesCircle"></span></div>
</button>
</form>

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;

我相信这一行存在问题:

if(isset($data->success) AND $data->success==true)

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)来验证重新收回。它将解决您的代码和头痛问题,因为它们会使其保持最新状态。
