php – 需要帮助reCAPTCHA – 不断变得不正确 – 验证码 – 溶胶
作者:互联网
我正在尝试将reCAPTCHA添加到我的网站,但在提交答案时不断收到错误的验证码错误.
谁能告诉我,如果我在做以下事情是否正确?
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 $error;
}
}
在我的html中,我插入了CAPTCHA,如下所示:
<form name="contactForm" method="post" action="index.php?id=contact&action=submit#contact">
<tr><td>Name</td><td><div align="right">
<input type="text" name="name_txt" class="input">
</div></td></tr>
<tr><td>Email</td><td><div align="right">
<input type="text" name="email_txt" class="input">
</div></td></tr>
<tr><td height="10"></td></tr>
<tr><td colspan="2">Message</td></tr>
<tr><td colspan="2"><textarea name="message_txt" class="textarea" style="width:200px; height:100px"></textarea></td></tr>
<tr><td colspan="2"><?php echo recaptcha_get_html($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,但会欣赏任何建设性的批评.
TIA
解决方法:
我已经解决了这个问题,这是我遇到的最不寻常的事情之一,我的语法是先前的:
<table>
<form>
<tr><td></td></tr>
</form>
</table>
我改成了这个:
<form>
<table>
<tr><td></td></tr>
</table>
</form>
由于此切换,recaptcha_response_field和recaptcha_challenge_field突然将值发布回表单.
我想不出为什么会这样,因为所有的MY表单变量都在切换之前被回发了.
谢谢大家指点.
