Witam,
chce zmodyfikować kod forum SMF 1.1.6, w taki sposób aby przy logowaniu zapisał hasło w formie nie shaszowanej do bazy. próbowałem za pomocą komendy $_POST['passwrd'] ale zapisuje mi puste pole do bazy a gdy użyje $_POST['user'] to wszystko pieknie działa. Nie wiem jak to rozgryść, przyznam że mało znam PHP, programowałem troche w C++/C#. Zmiany próbowałem robić w pliku z FTP /Source/Loginout.php . Poniżej kod w/w pliku.
