Я включил Google Recaptcha на свой сайт.Google reCAPTCHA не работает
Тем не менее, люди все еще могут заполнить форму и отправить почту, не заполняя captcha. (Таким образом, им не нужно решать головоломки, которые они могут просто получить прямо, из-за которых я, конечно, оставляю бонусы для ботов)
Итак, мне в основном нужен PHP-код, который проверяет, действительно ли пользователи действительно «отмечены» или «Завершено» Recaptcha. Поэтому они могут приступить к отправке почты.
Вот мой PHP код формы:
<!-- Start Contact Form -->
<div id="contact-form" class="contatct-form">
<div class="loader"></div>
<form method="post" action="mail.php">
<div class="row">
<div class="col-md-4">
<label for="name">Name<span class="required">*</span></label>
<span class="name-missing">Please enter your name</span>
<input id="name" name="name" type="text" value="" size="60">
</div>
<div class="col-md-4">
<label for="e-mail">Email<span class="required">*</span></label>
<span class="email-missing">Please enter a valid e-mail</span>
<input id="e-mail" name="email" type="text" value="" size="60">
</div>
<div class="col-md-4">
<label for="url">Website</label>
<input id="url" name="url" type="text" value="" size="80">
</div>
</div>
<div class="row">
<div class="col-md-12">
<label for="message">Add Your Comment</label>
<span class="message-missing">Say something!</span>
<textarea id="message" name="message" cols="45" rows="10"></textarea>
</br>
<!--Google reCAPTCHA-->
<?php
require_once('recaptchalib.php');
$publickey = "My Public Key"; // you got this from the signup page
echo recaptcha_get_html($publickey);
?>
<!--End Google reCAPTCHA-->
<input type="submit" name="submit" class="button" id="submit_btn" value="Send Message" onclick="return valtest();">
</div>
</div>
</form>
Вот мой mail.php код:
<?php
require_once('recaptchalib.php');
$privatekey = "My private key";
$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if (!$resp->is_valid) {
// What happens when the CAPTCHA was entered incorrectly
die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
"(reCAPTCHA said: " . $resp->error . ")");
} else {
$sendto = "[email protected]";
$name=$_REQUEST['name'];
$usermail = $_REQUEST['email'];
$url=$_REQUEST['url'];
$content = nl2br($_POST['message']);
$subject = "Web Enquiry";
$headers = "From: " . strip_tags($name) . "\r\n";
$headers .= "Reply-To: ". strip_tags($usermail) . "\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html;charset=utf-8 \r\n";
$msg = "<html><body style='font-family:Arial,sans-serif;'>";
$msg .= "<h2 style='font-weight:bold;border-bottom:1px dotted #ccc;'>New Enquiry</h2>\r\n";
$msg .= "<p><strong>Sent by:</strong> ".$usermail."</p>\r\n";
$msg .= "<p><strong>Client Name:</strong> ".$name."</p>\r\n";
$msg .= "<p><strong>Message:</strong> ".$content."</p>\r\n";
$msg .= "<p><strong>Contact:</strong> ".$url."</p>\r\n";
$msg .= "</body></html>";
mail($sendto, $subject, $msg, $headers);
echo "<script>window.location =\"index.php\";</script>";

<!--End Google reCAPTCHA-->
с

<!--End Google reCAPTCHA-->
он будет отображать виджет, но люди все еще может заполнить форму и отправить почту без завершения капчу.
