reCaptcha打破我的代码

Question

我已经连续几周收到垃圾邮件。我能够通过表格在我的几页上获得一些recaptcha，但有一些不起作用。我的一些网站是用CMS完成的，其他部分是从头开始的。所以......有一个叫做sign-up.php的页面。这是最受欢迎的表单。表单结构有点奇怪。我添加的唯一东西是标签内部的php标签和recaptcha脚本。我发现这个表单发布的文件，但是当我添加google recaptcha告诉我添加的任何内容时，它会崩溃。我试着添加一些简单的行，比如include_once（recaptchalib.php），它仍然崩溃。

我会建议看看EasyCaptchas，因为它是很容易（PHP记）要使用比较验证码？

该代码示例已损坏:)。查询字符串中缺少?。这是一个正确的例子：

<?php 

session_start(); 

if(isset($_POST['captcha'])) { 
    $captcha = $_POST['captcha']; 
    $uid   = $_SESSION['uid']; 
    echo file_get_contents("http://www.easycaptchas.com/check.aspx?sessionid=$uid&input=$captcha"); 
    exit(); 
} 

$uid = $_SESSION['uid'] = uniqid(); 

?> 
<form method="post"> 
    <input name="captcha" size="16"/> 
    <img id="captchaimg" src="http://www.EasyCaptchas.com/<?= $uid; ?>.captcha?" /> 
    <a href="http://www.easycaptchas.com/" onclick="document.getElementById('captchaimg').src+='rf=1';return false;" style="font-size:9px">refresh</a><br /> 
    <!-- Free Captcha provided courtesy of www.EasyCaptchas.com (please do not remove this link) --> 
    <noscript><a href="http://www.easycaptchas.com/" onclick="return false;" style="display:none">Captcha</a></noscript> 
</form> 
<script> 
    console.log(document.getElementById('captchaimg').src); 
</script>
