Witam mam tu skrypt działającego SB.


Skrypt posiada logowanie po zalogowaniu można dopiero pisać, ale tak naprawde logowanie nie jest mi wcale potrzebne bo mam na stronie, i teraz prosiłbym o pomoc jak przerobić skrypt aby po zalogowaniu na strone można było pisać i żeby wyświetlal nazwe użytkownika ze strony.
Wygląda to tak puki co(obrazek dużo wyjaśni):


Pozdrawiam
