我正在尝试将 ReCaptcha 添加到我创建的用于共享内容的邮件表单中,但由于某种原因,当我点击“提交”时验证码没有得到验证,这意味着即使你在验证码中输入了错误的文本,该表格仍将发送电子邮件。我正在使用 joomla 2.5.8,recaptcha 插件已启用(尽管我认为它没有被初始化,因为我自己添加了 recaptchalib.php 并且我在邮件表单代码中包含了 publickey 和 privatekey 的引用)。
任何帮助将不胜感激!谢谢!!这是代码:
<?php require_once('recaptchalib.php'); ?>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script language="javascript" type="text/javascript">
function validateEmail($email)
{
var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
if( !emailReg.test( $email ) )
{
return false;
}
else
{
return true;
}
}
function validateForm()
{
var form = document.mailForm;
if (form.recipient.value == "" || validateEmail(form.recipient.value)==false)
{
alert("bad email");
return false;
}
if (form.subject.value == "")
{
alert("please enter subject");
return false;
}
if (form.content.value == "")
{
alert("please enter massage");
return false;
}
<?php
$privatekey = "privatekey";
$resp = recaptcha_check_answer($privatekey,$_SERVER["REMOTE_ADDR"],$_POST["recaptcha_challenge_field"],$_POST["recaptcha_response_field"]); ?>
if (!$resp->is_valid)
{
alert("try again");
return false;
}
return true;
}
</script>
<?php
if($this->success=='1')
{
echo JText::_('MAIL_SEND_SUCCESSFULLY');
}
elseif($this->success=='0')
{
echo JText::_('MAIL_SEND_FAILED');
}
?>
<div id="SendMail">
<h2>send mail</h2>
<form action="index.php" name="mailForm" method="post" onsubmit="return validateForm()">
