Нет ошибок, мой PHP-код просто не входит в систему.

Question

Halo there,

У меня есть PHP-скрипт и форма входа в систему, которая не работает при попытке входа в систему, и никаких ошибок не отображается. Когда он предположим, чтобы войти в систему, он очистит мои поля имени пользователя и пароля. он не проходит.

Ниже приведен мой код.

<?php session_start(); ?>

header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1 
header("Cache-Control: post-check=0, pre-check=0", false);

Использование $_POST вместо @$HTTP_POST_VARS я надеюсь, что он будет делать, если не имеет каких-либо проблемы с базой данных
