upload file.... controllo codice

[oly1982]

non sò quale protrebbe essere il problema
per conoscere qualcosa in più puoi analizzare la variabile
$_FILE['upfile']['error'] in questo modo

switch ($_FILE['upfile']['error'])
{     
     case 0:
             $msg = "No Error"; // comment this out if you don't want a message to appear on success.
             break;
     case 1:
              $msg = "The file is bigger than this PHP installation allows";
              break;
      case 2:
              $msg = "The file is bigger than this form allows";
              break;
       case 3:
              $msg = "Only part of the file was uploaded";
              break;
       case 4:
             $msg = "No file was uploaded";
              break;
       case 6:
             $msg = "Missing a temporary folder";
              break;
       case 7:
             $msg = "Failed to write file to disk";
             break;
       case 8:
             $msg = "File upload stopped by extension";
             break;
       default:
            $msg = "unknown error ".$_FILES['Filedata']['error'];
            break;
}

If ($msg)
    $stringData = "Error: ".$_FILE['upfile']['error']." Error Info: ".$msg;
else
   $stringData = "1"; // This is required for onComplete to fire on Mac OSX
echo $stringData; 

l'array error si articola così

<?
array(
       0=>"There is no error, the file uploaded with success",
       1=>"The uploaded file exceeds the upload_max_filesize directive in php.ini",
       2=>"The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form"
       3=>"The uploaded file was only partially uploaded",
       4=>"No file was uploaded",
       6=>"Missing a temporary folder"
);
?>

in questo modo saprai qualcosina in più e magari puoi capire come intervenire
