Non funziona il controllo sulla dimensione del file

[blackx]

Ho questo cgi per l'upload del file.

Il controlo alla 40a riga (// Controllo dimensioni ) per la dimensione del file viene totalmente ignorato..

Stai confrontando il nome del file con la dimensione.
Utilizza $_FILES['userfile']['size'] oppure http://www.php.net/filesize

[blackx]

Intendi così...?

         // Controllo dimensioni
        $size_bytes =500000;                     //51200000 bytes = 50000KB.
        //$file_size = $new_file['size'];
        //$new_file = $_FILES['file'.$i];
        
        if ($_FILES['userfile']['size'] > $size_bytes){
          echo "Immagine troppogrande";
          exit;
        } 

[blackx]

in questo modo me le restituisce tutte come troppo grandi...

[blackx]

Nessun idea ?
