我已经继承了一个项目，它使用Kohana MVC框架，它是Kohan_auth类来注册某个人。提交注册时，它会向下面的课程提交表格帖子。我没有看到 - >寄存器在哪里使用，或者是什么意思，或者如何调试或解决这个问题。请帮忙。Kohana PHP框架Kohan_auth不能调试或使用
Auth::instance()->register($_POST, TRUE);
不输入数据，只是重定向回注册页面，没有错误消息。我如何调试这个，单元测试也不能正常工作，因为它们需要较老的phpunit版本。
验证::实例（）似乎去这个代码
* @package Useradmin/Auth
* @author Gabriel R. Giannattasio
*/
abstract class Useradmin_Auth extends Kohana_Auth {
/**
* Singleton pattern
*
* @return Auth
*/
public static function instance()
{
if (! isset(Auth::$_instance))
{
// Load the configuration for this type
$config = Kohana::$config->load('auth');
if (! $type = $config->get('driver'))
{
$type = 'file';
}
// Set the session class name
$class = 'Auth_'.ucfirst($type);
$config->set("useradmin", Kohana::$config->load('useradmin.auth'));
// Create a new session instance
Auth::$_instance = new $class($config);
}
return Auth::$_instance;
}
}
延伸这个
