带有自定义PHPBB登录页面的验证码

Question

当您多次错误输入密码但不确定如何操作时，我正在尝试在屏幕上弹出验证码。 我已经找到了很多关于此的页面，但是它们都涉及使用模板，而这些页面都没有解释我必须在表单中添加的内容。

这是到目前为止我得到的。

define('IN_PHPBB', true);
    global $auth, $db, $cache, $config, $user, $phpbb_root_path, $phpEx, $template;
    $phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : '../main/';
    $phpEx = substr(strrchr(__FILE__, '.'), 1);
    include($phpbb_root_path . 'common.' . $phpEx);

    $user->session_begin();
    $auth->acl($user->data);

    $remember = $remember==1?true:false;
    $result = $auth->login($username, $password, $remember);

    if ($result['status'] == LOGIN_SUCCESS){
        return "LOGIN_SUCCESS";
        //Launch captcha
    }else{
        if($result['status']==LOGIN_ERROR_ATTEMPTS){
            return "LOGIN_ERROR_ATTEMPTS";
        }
        if($result['status'] == LOGIN_ERROR_EXTERNAL_AUTH){
            return "No profile exists.";
        }elseif($result['status'] == LOGIN_BREAK){
            return "Failed to create session.";
        }elseif($result['status'] == LOGIN_ERROR_PASSWORD){
            return "Incorrect Password.";
        }elseif($result['status'] == LOGIN_ERROR_USERNAME){
            return "Invalid Username.";
        }elseif($result['status'] == LOGIN_ERROR_PASSWORD_CONVERT){
            return "Internal error, failed to convert password.";
        }elseif($result['status'] == LOGIN_ERROR_ACTIVE){
            return "User is inactive.";
        }
    }
