以下でお手伝いできますか？
Joomla1.5サイトでユーザー登録を使い始めました...
スパムボットがサイトに登録されています
サイトのキャプチャを使用しましたが-http ://www.white-hat-web-design.co.uk/blog/php-captcha-security-images/
登録ページのリンクでの（検証なしの）動作-http://www.mycarhelpline.com/index.php?option= com_user&view=register& Itemid=79
ただし、登録ページで同じことが検証されていません。
検証コード
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 {
}
Joomlaのどのファイル/行（controller.php、default.php、view.html.php）にこのコードを入れる必要がありますか。異なる行の異なるファイルで順列/組み合わせを試しましたが、機能しません。
Pl提案
こんにちは-変更を加えても機能しません。実際、controller.phpにサーバーエラーが表示されます-完全なコードをここに配置します
