你能在下面帮忙吗：
我已经开始使用用户注册我的 Joomla 1.5 网站...
垃圾邮件机器人正在网站上注册
虽然我使用了来自网站的验证码——http: //www.white-hat-web-design.co.uk/blog/php-captcha-security-images/
它在注册页面链接上工作（未经验证） - http://www.mycarhelpline.com/index.php?option=com_user&view=register&Itemid=79
但是，在注册页面中没有得到验证，
验证码
session_start();
if( isset($_POST['submit'])) {
if( $_SESSION['security_code'] == $_POST['security_code'] &&
!empty($_SESSION['security_code'] ) ) {
// Insert you code for processing the form here, e.g emailing the
submission, entering it into a database.
echo 'Thank you. Your message said "'.$_POST['message'].'"';
unset($_SESSION['security_code']);
} else {
// Insert your code for showing an error message here
echo 'Sorry, you have provided an invalid security code';
}
} else {
}
我需要在 Joomla 的哪个文件/行 - controller.php、default.php 和 view.html.php 中放入此代码。我已经尝试在不同行的不同文件上进行排列/组合，但它不起作用。
请建议
嗨 - 即使在进行更改后它也无法正常工作，事实上它在controller.php 中显示服务器错误 - 将完整的代码放在这里

echo 'Thank you.';
unset($_SESSION['security_code']);

// Insert your code for showing an error message here
echo 'Sorry, you have provided an invalid security code';
