实际密钥已编辑"我正在使用 ReCaptcha 实现一个简单的登录表单。验证码给了我这个错误："未正确输入 reCAPTCHA。回去再试一次。(reCAPTCHA 说：不正确的验证码-sol)">这是我的代码：
索引.php
<table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<form name="form1" method="post" action="verify.php">
<td>
<table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">
<tr>
<td colspan="3"><strong>Member Login </strong></td>
</tr>
<tr>
<td width="78">Username</td>
<td width="6">:</td>
<td width="294"><input name="myusername" type="text" id="myusername" /></td>
</tr>
<tr>
<td>Password</td>
<td>:</td>
<td><input name="mypassword" type="text" id="mypassword" /></td>
</tr>
<tr>
<td> </td>
<td> </td>
<td><input type="submit" name="Submit" value="Login" /></td>
</tr>
</table>
</td>
</form>
</tr>
</table>

验证.php
<?php
echo "<pre> _POST: =========n";
print_r($_POST);
echo "n=========n</pre>";
require_once('recaptchalib.php');
$privatekey = "private_key_here";
$resp = recaptcha_check_answer ($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 {
// Your code here to handle a successful verification
}
?>
我不知道我做错了什么。有什么帮助吗？
附言是的，我确实在同一目录中.php有 recaptchalib。
看到这个...
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]
$_POST变量数组来自提交时的form数据。 问题是，当您未能将这些字段放入form容器中时，表单数据发布数组如何包含recaptcha_challenge_field和recaptcha_response_field？
您必须将 reCaptcha 小部件放在form容器内，或放在<form>和</form>标签之间。
<form name="form1" method="post" action="verify.php">
.... the rest of your form here
<script type="text/javascript"

<input type="hidden" name="recaptcha_response_field"

</form>
但是，不确定为什么您在执行print_r($_POST);时没有注意到丢失的帖子数据
