[gd] non salva il file

[Francis87]

ciao a tutti!

questo scriptino non mi salva il file dell'immagine che creo.

sapreste dirmi come mai?

  $gallery = $_POST['ngallery'];
  $uploaddir = 'gallery/images';
  $upload_dir1 = $uploaddir."_".$_POST["ngallery"]."/";
  $uploadfile1 = $upload_dir1 . $_FILES['userfile']['name'];
  $filename = $_FILES['userfile']['name'];

  if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile1)) {
   $mex = "The files have been successfully uploaded.";
  }
  else {
   print "<pre>";
   print "Possible file upload attack!  Here's some debugging info:\n";
   print_r($_FILES);
   print_r($_FILES['userfile']['error']);
   print "</pre>";
  }
 $url = $uploadfile;
 $im = getimagesize($url);
 if ($im[0] >= $im[1]) {
  $div = $im[0]/100;
 }
 else {
  $div = $im[1]/100;
 }
 $newwid = ceil($im[0]/$div);
 $newhei = ceil($im[1]/$div);

 $err = "";
 switch ($im[2]) {
  case 1:
   $oldim = imagecreatefromgif($url);
   break;
  case 2:
   $oldim = imagecreatefromjpeg($url);
   break;
  case 3:
   $oldim = imagecreatefrompng($url);
   break;
  default:
   $err = "We are sorry but this image format isn't valid. Only GIF, JPG, PNG are supported.";
 }

 $tdir = $upload_dir1."thumbs_".$gallery."/TN_".$filename;

 if ($err == "") {
  $newim = @imagecreatetruecolor($newwid,$newhei) or die("Cannot Initialize new GD image stream");
  imagecopyresized($newim,$oldim,0,0,0,0,$newwid,$newhei,$im[0],$im[1]);
  switch ($im[2]) {
   case 1:
    $oldim = imagecreatefromgif($url);
    header('Content-Type: image/gif');
    imagegif($newim,$tdir);
    break;
   case 2:
    $oldim = imagecreatefromjpeg($url);
    header('Content-Type: image/jpeg');
    imagejpeg($newim,$tdir,100);
    break;
   case 3:
    $oldim = imagecreatefrompng($url);
    header('Content-Type: image/png'); 
    imagepng($newim,$tdir);
    break;
  }
 }
 imagedestroy($newim);
 imagedestroy($oldim);

grazie

nn ottieni nessun tipo di errore?? prova a controllare i percorsi di $tdir.

[Francis87]

nessun errore. quello ke dovrebbe fare è crearmi una thumbnail che visualizzo nella gallery. ma nella gallery mi dà l'avviso che manca la thumbnail x l'immagine ke ho appena uploadato.

$tdir è giusto, l'ho controllato più volte. x es potrebbe essere:

gallery/images_02/thumbs_02/file.jpg

prova con error_reporting(E_ALL); all'inizio del codice. se lo script non ti genera errori, vuol dire che la tb viene creata. prova a controllare nella cartella dove dovrebbe venire salvata.

[Francis87]

ehm...

ecco, si, c'è qualcosa ke non va

controlla sia i notice sia i warning

[Francis87]

ok sono riuscito a risolvere!

Qui il codice x l'upload e il ridimensionamento delle immagini!

 if ($_POST["upload"] == "upload") {
  $gallery = $_POST['ngallery'];
  $uploaddir = 'gallery/images';
  $upload_dir1 = $uploaddir."_".$_POST["ngallery"]."/";
  $uploadfile1 = $upload_dir1 . $_FILES['userfile']['name'];
  $filename = $_FILES['userfile']['name'];

  if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile1)) {
   $mex = "The files have been successfully uploaded.";
  }
  else {
   print "<pre>";
   print "Possible file upload attack!  Here's some debugging info:\n";
   print_r($_FILES);
   print_r($_FILES['userfile']['error']);
   print "</pre>";
  }
 $url = $uploadfile1;
 $im = getimagesize($url);
 if ($im[0] >= $im[1]) {
  $div = ceil($im[0]/100);
 }
 else {
  $div = ceil($im[1]/100);
 }
 $newwid = ceil($im[0]/$div);
 $newhei = ceil($im[1]/$div);

 $err = "";
 switch ($im[2]) {
  case 1:
   $oldim = imagecreatefromgif($url);
   break;
  case 2:
   $oldim = imagecreatefromjpeg($url);
   break;
  case 3:
   $oldim = imagecreatefrompng($url);
   break;
  default:
   $err = "We are sorry but this image format isn't valid. Only GIF, JPG, PNG are supported.";
 }

 $tdir = $upload_dir1."thumbs_".$gallery."/TN_".$filename;

 if ($err == "") {
  $newim = @imagecreatetruecolor($newwid,$newhei) or die("Cannot Initialize new GD image stream");
  imagecopyresized($newim,$oldim,0,0,0,0,$newwid,$newhei,$im[0],$im[1]);
  switch ($im[2]) {
   case 1:
    $oldim = imagecreatefromgif($url);
    imagegif($newim,$tdir);
    break;
   case 2:
    $oldim = imagecreatefromjpeg($url);
    imagejpeg($newim,$tdir,100);
    break;
   case 3:
    $oldim = imagecreatefrompng($url);
    imagepng($newim,$tdir);
    break;
  }
 }
 imagedestroy($newim);
 imagedestroy($oldim);
 }

solo una cosa:

Notice: Undefined index: reg in c:\hosting\fanarctica.com\wwwroot\fanscorner.php on line 95

if ($_GET['reg'] == "in") { print .....

come mai fa anke ste stupidate?

[marketto]

con l'error reporting su all php ti visualizza tutti gli errori, i warning ed i notice. quest'ultimi nn sono veri e propri errori, ma avvisi su pezzi di codice formalmente non corretto.
nel caso specifico la chiave reg dell'array $_GET non esiste, e quindi arriva il notice. per toglierlo devi trovare una sintassi alternativa per la condizione dell'if...
