在我的Web表单上使用reCAPTCHA和PHP在使用XAMPP测试时不起作用？

我只是尝试将reCAPTCHA插入我的Web表单，并使用XAMPP1.8.1对其进行测试。发生的情况如下： 1.reCAPTCHA在我的表单底部成功显示 2.我填写了表格，电子邮件成功转发到我的电子邮件地址

问题是reCAPTCHA字段不是强制性的，所以无论我是否输入所需的两个单词，我仍然会收到电子邮件。如果用户没有填写reCAPTCHA字段，那么这个reCAPTCHA字段不应该是强制性的，这样我就无法收到消息吗

不知道我做错了什么

下面是我的email.php代码（reCAPTCHA代码位于底部）：

您忘记在email.php中验证reCaptcha

您不能将

表单

放在

表单

中。创建一个包含姓名输入、电子邮件输入、消息输入和reCaptcha（不含

）的表单。使用

verify.php

内部

email.php

中的代码，如下所示：

// load recaptcha library 
require_once('recaptchalib.php');
// config - you can read it from some config file
$publickey = "my_public_key_goes_here"; // you got this from the signup page
$privatekey = "my_private_code_goes_here";


// rest of your code


// Is form sent?
if( isset( $_POST['submit'] ) ) {

    // begin: reCAPTCHA CODE - validate answer

    $resp = recaptcha_check_answer ($privatekey,
                            $_SERVER["REMOTE_ADDR"],
                            $_POST["recaptcha_challenge_field"],
                            $_POST["recaptcha_response_field"]);

    if (!$resp->is_valid) {
        $errors[] = 'Please enter a valid captcha';
    }

    // end: reCAPTCHA CODE - validate ansver

    // Validate $_POST['name']

    // rest of your code

}

<!-- rest of your HTML -->

     <form method="POST"> <!-- you don't need `action` for the same page -->

        <!-- rest of your form -->

        <!-- begin: reCAPTCHA CODE - print widget -->

        <?php echo recaptcha_get_html($publickey); ?></br>

        <!-- end: reCAPTCHA CODE - print widget -->

        <input name="submit" type="submit" value="Submit" />

     </form>

//加载recaptcha库
require_once（'recaptchalib.php'）；
//配置-您可以从一些配置文件中读取它
$publickey=“我的公钥在这里”//你从注册页面上看到的
$privatekey=“我的私人密码在这里”；
//代码的其余部分
//表格寄出了吗？
如果（isset（$_POST['submit']））{
//开始：reCAPTCHA代码-验证答案
$resp=repatcha\u check\u response（$privatekey，
$\u服务器[“远程地址”]，
$\u POST[“重演挑战场”]，
$(POST[“recaptcha_response_field”])；
如果（！$resp->有效）{
$errors[]=“请输入有效的验证码”；
}
//结束：reCAPTCHA代码-验证ANVER
//验证$\u POST['name']
//代码的其余部分
}

最简单的工作示例：

<?php 

require_once('recaptchalib.php'); 

$publickey = "your_public_key"; 
$privatekey = "your_private_key"; 

if( isset( $_POST["recaptcha_response_field"] ) ) 
{ 
    $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); 

    if(!$resp->is_valid) { 
        echo "reCaptcha incorrect"; 
    } else {
        echo "reCaptcha OK";        
    } 
} 

?>

<form method="POST">

    <? echo recaptcha_get_html($publickey); ?>

</form>

注释不是编写代码的好地方。最好编辑问题以添加一些代码。我用你们的代码做一个最简单的工作示例-。请参阅上面我的答案中的代码。如果有些东西不起作用，请在许多地方使用
echo
和
print\r
，查看PHP正在做什么（一步一步）。例如：您可以在
if（empty（$errors））
之前添加
print\r（$errors）
$errors
决定发送邮件。顺便说一下：您应该显示邮件“mail was send”，甚至向客户端发送邮件-一些客户端希望这样。客户可能会认为由于并没有信息，所以出现了问题，他可能会反复使用联系方式。若有人使用假邮件，你们会立即收到来自服务器的消息“我不能发送邮件”。有人可以使用其他人的邮件。您的邮件将问题告知了那个人-您必须添加取消订阅的机会。它是UX（用户体验）的一部分。最后-在PHP
标题（“刷新：5；url=index.html”）中使用错误颜色（大部分为红色）和消息颜色（绿色）或HTML标记
内部
标记。使用JavaScript，您甚至可以倒计时-请参阅：
// load recaptcha library 
require_once('recaptchalib.php');
// config - you can read it from some config file
$publickey = "my_public_key_goes_here"; // you got this from the signup page
$privatekey = "my_private_code_goes_here";
