在joomla中使用php插件安装reCaptcha K2

我试图在K2前端子表单上实现reCaptcha。我已经下载了PHP库，安装了它并可以成功地以submition形式显示capcha图像，但最后一步让我感到困惑。我需要把这些代码形成行动php文件：在joomla中使用php插件安装reCaptcha K2

<?php 
    require_once(JPATH_SITE.'/libraries/recaptcha/recaptchalib.php'); 
    $privatekey = "MY PRIVATE KEY"; 
    $resp = recaptcha_check_answer ($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 { 
    alert(0); 
    } 
    ?>

的问题是，操作文件恰好是index.php出于某种原因。如果我只是把那段代码放在那里，主页停止加载警告，我错过了验证码键。我将在下面发布我的K2frontend php文件，希望你能帮助我，因为这对我来说是非常重要的功能。

<?php 
defined('_JEXEC') or die('Restricted access'); 

$document = & JFactory::getDocument(); 
$document->addScriptDeclaration(" 
    Joomla.submitbutton = function(pressbutton){ 
     if (pressbutton == 'cancel') { 
      submitform(pressbutton); 
      return; 
     } 
     if (\$K2.trim(\$K2('#title').val()) == '') { 
      alert('".JText::_('K2_ITEM_MUST_HAVE_A_TITLE', true)."'); 
     } 
     else if (\$K2.trim(\$K2('#catid').val()) == '0') { 
      alert('".JText::_('K2_PLEASE_SELECT_A_CATEGORY', true)."'); 
     } 
     else { 
      syncExtraFieldsEditor(); 
      \$K2('#selectedTags option').attr('selected', 'selected'); 
      submitform(pressbutton); 
     } 
    } 
");

如果您在管理部分工作您可以在项目控制器的保存功能中验证验证码。在此文件中administrator/components/com_k2/controllers/item.php检查以下功能并添加代码。

function save() { 
JRequest::checkToken() or jexit('Invalid Token'); 
//add library and captcha validation code here 
$model = & $this->getModel('item'); 
$model->save(); 
}

最好检查或尝试插件。
