用自定義PHPBB登錄頁面的驗證碼

Question

我試圖在屏幕上輸入密碼錯誤次數太多但不知道如何去解決時在屏幕上出現驗證碼彈出窗口。我已經找到了很多關於這個的網頁，但他們都涉及到使用模板，這些網頁都沒有解釋我必須將其放到我的表單中。

這是我到目前爲止。

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."; 
     } 
    }
