Question

这是我的enquiry.php文件，您可以看到的代码是recaptcha框/表单，因为您将看到我已经包含了我的响应操作，如果重新访问框是＆n，则show_error函数输出＃39; t勾选 - 这是有效的，但如果勾选方框并且表格填写正确，则不会将我重定向到thank-you.html

<?php

$email_to = "billy.farroll@hotmail.com";

if($_POST){

$name;
$telephone;
$email;
$comment;
$captcha;

if(isset($_POST['name']))
$name=$_POST["name"];
if(isset($_POST['telephone']))
$telephone=$_POST["telephone"];
if(isset($_POST['email']))
$email=$_POST["email"];
if(isset($_POST['comment']))
$comment=$_POST["comment"];
if(isset($_POST['g-recaptcha-response']))
$captcha=$_POST['g-recaptcha-response'];



if (empty($name))
{
    show_error("Oops! you forgot to fill in your name, Please go back to the homepage and try again");
}


if (empty($telephone))
{
    show_error("Oops! you forgot to fill in your telephone, Please go back to the homepage and try again");
}


if (empty($email))
{
    show_error("Oops! you forgot to fill in your email, Please go back to the homepage and try again");
}



$email = htmlspecialchars($_POST['email']);
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email) || (!$captcha))
{
    show_error("Please tick the box");

}


} else {

    $response=json_decode(file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=6Lf2sEIUAAAAAMio98GU_V6gki_mGxS3Z6WMBmA9&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']), true);
    if($response['success'] == false)

    {

        show_error("Please tick the box");

    }

    else

    {


$email_from = $_POST["email"];
$message = $_POST["message"];
$email_subject = "Enquiry Form";
$headers =
"From: $email_from .\n";
"Reply-To: $email_from .\n";
$message = 
"Name: ". $name . 
"\r\nTelephone Number: " . $telephone . 
"\r\nEmail Address: " . $email . 
 "\r\n\r\n\r\nComments :" . $comment;

ini_set("sendmail_from", $email_from);
$sent = mail($email_to, $email_subject, $message, $headers, "-f" .$email_from);
if ($sent)
{

    header ('location: thank-you.html'); 

        }
    }
}




?>

这是我的表单HTML代码，您可以看到我已经在下面插入了我的recaptcha框代码以及链接到我的enquiry.php文件

我找到了这个问题的答案，请参阅修改后的PHP代码：

$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 -->");
    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 -->");

        }

// NEW RECAPTCHA

Google Recaptcha框无效。如果没有勾选则可以正常工作，但如果勾选则不会工作
