Witam napisałem sobie prostą klasę która wygląda tak:

[PHP] pobierz, plaintext 
<?php

[PHP] pobierz, plaintext 

otóż mam problem z modyfikacją danych.
funkcja za to odpowiedzialna wygląda tak:

[PHP] pobierz, plaintext 
    public static function save()
    {
        if ($this->uid)
        {
            $query = sprintf('UPDATE %susers SET password = "%s", gadugadu = "%s", email = "%s", pseudo = "%s" WHERE user_id = %d', DB_TBL_PREFIX,
                 mysql_real_escape_string($this->password, $GLOBALS['DB']), mysql_real_escape_string($this->gadugadu, $GLOBALS['DB']),
                 mysql_real_escape_string($this->email, $GLOBALS['DB']), mysql_real_escape_string($this->pseudo, $GLOBALS['DB']), $uid);
            mysql_query($query, $GLOBALS['DB']);
        }
        else
        {
            $query = "INSERT INTO ".DB_TBL_PREFIX."users SET username = '".mysql_real_escape_string($this->username, $GLOBALS['DB'])."',
               password = '".mysql_real_escape_string($this->password, $GLOBALS['DB'])."', position = '".mysql_real_escape_string($this->position, $GLOBALS['DB'])."',
               gadugadu = '".mysql_real_escape_string($this->gadugadu, $GLOBALS['DB'])."', email = '".mysql_real_escape_string($this->email, $GLOBALS['DB'])."',
               pseudo = '".mysql_real_escape_string($this->pseudo, $GLOBALS['DB'])."'";
            mysql_query($query, $GLOBALS['DB']);
        }
    }
[PHP] pobierz, plaintext 

podczas próby modyfikacji otrzymuje błąd:



dodam jeszcze że skrypt wywołuje tak:

Nie możesz odwoływać się do składowych klasy poprzez $this w metodach zadeklarowanych jako statyczne, stąd ten błąd:

[PHP] pobierz, plaintext 
public static function save()
    {
        if ($this->uid)
        {
...
