需要帮助reCAPTCHA - 不断变得不正确 - captcha-sol [英] Need help with reCAPTCHA - keep getting incorrect-captcha-sol

问题描述

我正在尝试向我的网站添加reCAPTCHA，但在提交答案时，一直收到错误 - captcha-sol 错误。

任何人都可以告诉我，我是否正确执行以下操作？

我有一个通用的index.php，其中包含contact.php。在contact.php中，我插入了以下代码：

  require_once（'recaptchalib.php'）; 
 $ publickey =XXXX; 
 $ privatekey =XXXX; 
 
 // reCAPTCHA的响应
 $ resp = null; 
 // reCAPTCHA的错误代码，如果有的话
 $ 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网站查询'; 
 $ 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 {
＃设置错误代码，以便我们可以显示它。您也可以使用
＃die（reCAPTCHA failed），但使用错误消息是
＃更加便于用户使用
 
 $ error = $ resp->错误; 
 
 echo $ error; 
} 
  

}

在我的HTML中，我插入了这样的验证码：

 < form name =contactFormmethod =postaction = ？的index.php ID =接触&安培;行动=提交＃接触> 
< tr>< td>名称< / td>< td>< div align =right> 
< input type =textname =name_txtclass =input> 
< / div>< / td>< / tr> 
< tr>< td>电子邮件< / td>< td>< div align =right> 
< input type =textname =email_txtclass =input> 
< / div>< / td>< / tr> 
< tr>< td height =10>< / td>< / tr> 
< tr>< td colspan =2>讯息< / td>< / tr> 
< tr>< td colspan =2>< / textarea>< textarea name =message_txtclass =textareastyle =width：200px; height：100px< ; / TD>< / TR> 
< tr>< td colspan =2><？php echo recaptcha_get_html（$ publickey，$ error）; ？>< / TD>< / TR> 
< tr>< td colspan =2style =padding-top：10px;>< input type =imagesrc =images / header_06.gifname =submit值= 提交 >< / TD>< / TR> 
< / form> 
  

我看不出我做错了什么，但会感谢任何有建设性的批评。

TIA

解决方案

我解决了这个问题，它是最不寻常的事情之一我碰到过，我的语法是：

 < table> 
< form> 
< tr>< td>< / td>< / tr> 
< / form> 
< / table> 
  

我将其更改为：

 <形式> 
< table> 
< tr>< td>< / td>< / tr> 
< / table> 
< / form> 
  

由于此切换，突然间 recaptcha_response_field 和 recaptcha_challenge_field 将值重新发送回表单。

我不明白为什么会这样，因为所有MY表单变量都发布了返回之前切换。

感谢所有的指针。

I am trying to add a reCAPTCHA to my site, but keep getting incorrect-captcha-sol error when I submit the answer.

Can anyone tell me if I am correct in doing the following?

I have a generic index.php, which includes contact.php. In contact.php I have inserted the following code:

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;
}

}

In my html I inserted the CAPTCHA like this:

<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>

I cannot see that I am doing anything wrong, but would appreciate any constructive criticism.

TIA

解决方案

I have solved this, it is one of the most unusual things I have come across, my syntax was previously:

<table>
<form>
<tr><td></td></tr>
</form>
</table>

I changed it to this:

<form>
<table>
<tr><td></td></tr>
</table>
</form>

Because of this switch, suddenly the recaptcha_response_field and recaptcha_challenge_field are posting values back to the form.

I cannot think why this because all MY form variables got posted back before the switch.

Thanks all for the pointers.
