Google reCAPTCHA无法正常工作
我将Google Recaptcha集成到了我的网站。Google reCAPTCHA无法正常工作
但是,人们仍然可以填写表单并发送邮件,而无需完成验证码。 (所以他们不必解决任何他们可以直接通过的谜题,当然这使我可以*地运行机器人)
所以,我基本上需要PHP代码来检查用户是否实际上“滴答”或“完成”了Recaptcha。那么他们可以继续发送邮件。
这里是我的PHP表单代码:
<!-- 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>
这里是我的mail.php代码:
<?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>";

它会显示小工具,但人们仍然可以填写表格,并没有完成验证码发送邮件。你有
首先要检查的ReCaptcha isset:
<?php
$errMsg = "";
$succMsg = "";
/**************************/
/* GOOGLE reCAPTCHA START */
/**************************/
require_once '../../reCAPTCHA/autoload.php';
$siteKey = 'sitekey';
$secret = 'secretkey';
/************************/
/* GOOGLE reCAPTCHA END */
/************************/
if ((isset($_POST['submit']) | !empty($_POST["submit"]))) {
if ((isset($_POST['g-recaptcha-response'])) && !empty($_POST["g-recaptcha-response"])) {
$recaptcha = new \ReCaptcha\ReCaptcha($secret);
$resp = $recaptcha->verify($_POST['g-recaptcha-response'], $_SERVER['REMOTE_ADDR']);
if ($resp->isSuccess()) {
$succMsg = "Success Message";
/**
* DO THE DB ENTRIES HERE
*/
}
} else {
$errMsg = "Error With Captcha";
}
}
?>
,你会从谷歌需要these文件。
他们在这里下载:require_once '../../reCAPTCHA/autoload.php';
