我正在尝试将 reCAPTCHA 添加到我的网站,但incorrect-captcha-sol
在提交答案时不断出错。
谁能告诉我以下操作是否正确?
我有一个通用的 index.php,其中包括 contact.php。在contact.php中,我插入了以下代码:
require_once('recaptchalib.php');
$publickey = "XXXX";
$privatekey = "XXXX";
//the response from reCAPTCHA
$resp = null;
//the error code from reCAPTCHA, if any
$error = null;
if ($_POST['submit']) {
$message = $_POST['message_txt'];
$name = $_POST['name_txt'];
$email = $_POST['email_txt'];
$emailBody = $message;
$to = 'xx';
$from = $name.' <'.$email.'>';
$subject = 'XX Website Enquiry';
$headers = 'From: '.$from;
$resp = recaptcha_check_answer($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]);
if ($resp->is_valid) {
echo 'captcha correct';
if (mail($to,$subject,$emailBody,$headers)) {
//echo 'mail sent';
$confirmation = 'sent';
}
else {
//echo 'mail not sent';
$confirmation = 'error';
}
} else {
# set the error code so that we can display it. You could also use
# die ("reCAPTCHA failed"), but using the error message is
# more user friendly
$error = $resp->error;
echo $error;
}
}
在我的 html 中,我像这样插入了验证码:
<form name="contactForm" method="post" action="index.php?id=contact&action=submit#contact">
<tr><td>Name</td><td><div align="right">
<input type="text" name="name_txt" class="input">
</div></td></tr>
<tr><td>Email</td><td><div align="right">
<input type="text" name="email_txt" class="input">
</div></td></tr>
<tr><td height="10"></td></tr>
<tr><td colspan="2">Message</td></tr>
<tr><td colspan="2"><textarea name="message_txt" class="textarea" style="width:200px; height:100px"></textarea></td></tr>
<tr><td colspan="2"><?php echo recaptcha_get_html($publickey, $error); ?></td></tr>
<tr><td colspan="2" style="padding-top:10px;"><input type="image" src="images/header_06.gif" name="submit" value="submit"></td></tr>
</form>
我看不出我做错了什么,但希望能得到任何帮助。
