[php]Filesize, Błąd przy porównywaniu rozmiarów Opcje

[felixk]

Witam, kolejny problem z formularzem (ale już chyba ostatni). Chce zrobić porównanie wielkości pliku i w zależności albo komunikat albo plik zostaje na serwerze. Oto co napisałem do tej pory:

[PHP] pobierz, plaintext 
 
     $max = 512000;
     $rozmiar = filesize("$upload_dir$file_name"); //linijka nr 60
     echo $rozmiar;
     if ($rozmiar > $max)
     {
     echo "Plik za duży";
     }

Dodam, że plik się nie ładuje.

a oto treść błędu, który występuje:

Warning: filesize() [function.filesize]: stat failed for upload_files/splyw_08.2009_074.jpg in /home/c/h/o/chojnowski/www/test/index.php on line 60

Powyżej pełny kod skryptu. Drugim problemem jest to, że nie wiem jak połączyć wynik sprawdzenia rozmiaru z tym, żeby upload dokonywał się po uzyskiwaniu poprawnego rozmiaru.

Z góry dziękuję za pomoc.

Co zwraca wartość 0 ? Pokaż kod po zmianach, jeśli warunek zostanie spełniony powinno być die
