Multiple images with thumbnails

Love the script, thanks. I used the single file upload and multiple file upload and like both...but is there a way to combine the features so I get thumbnails from the multiple file uploads? I've tried combiing the functions of both foto_upload.php and multiple_upload_example.php to get the script to create a thumb for each of the multiple file uploads with no luck. End result I'm hoping for is that a user can upload 10 pix at once (which works of course), rename each (which also works already) and create a thumbnail of each with same name saved to a thumb directory.

EG.
user uploads a.jpg,b.jpg,c.jpg,d.jpg
script does following:
saves a.jpg as PHOTOS/USER/*A's timestamp*.jpg
saves thumbnail of a.jpg as PHOTOS/USER/thumb/*A's timestamp*.jpg
saves b.jpg as PHOTOS/USER/*B's timestamp*.jpg
saves thumbnail of b.jpg as PHOTOS/USER/thumb/*B's timestamp*.jpg
saves c.jpg as PHOTOS/USER/*C's timestamp*.jpg
saves thumbnail of c.jpg as PHOTOS/USER/thumb/*C's timestamp*.jpg
saves d.jpg as PHOTOS/USER/*D's timestamp*.jpg
saves thumbnail of d.jpg as PHOTOS/USER/thumb/*D's timestamp*.jpg

Here's what I've got so far that isnt being cooperative (clicking submit DOES bring it back to this script so ignore the ACTION in the form)

You can use a new photo upload object for each photo. Next use a loop for all the file fields like here:

http://www.webdigity.com/index.php/topic,3015.0.Multiple+file+upload+%26amp%3B+storing+filenames.html

ok did this just b4 the form section:

if (isset($_POST['Submit']) && $_POST['Submit'] == "Upload")
   {
   foreach ($_FILES as $key => $val)
      {
      $foto_upload->the_temp_file = $_FILES[$key]['tmp_name'];
      $foto_upload->the_file = $val;
      $foto_upload->http_error = $_FILES[$key]['error'];
      $foto_upload->replace = "y";
      $foto_upload->do_filename_check = "n";
      if ($foto_upload->upload())
         {
         $foto_upload->process_image(false, true, true, 80);
         $foto_upload->message[] = "Processed foto: ".$foto_upload->file_copy."!"; // "file_copy is the name of the foto"
         }
      }
   }

and now get an error (Notice: Array to string conversion.....) regard wht appears to be  here...

   function get_extension($from_file) {
      $ext = strtolower(strrchr($from_file,"."));
      return $ext;
   }
in the upload_class.php which i changed nothing in

I have the php code always before all html, try this the error look to me that you form is wrong... post this here too. and check how I use html and php in files

the php is b4 the html like this...

if (isset($_POST['Submit']) && $_POST['Submit'] == "Upload")
   {
   foreach ($_FILES as $key => $val)
      {
      $foto_upload->the_temp_file = $_FILES[$key]['tmp_name'];
      $foto_upload->the_file = $val;
      $foto_upload->http_error = $_FILES[$key]['error'];
      $foto_upload->replace = "y";
      $foto_upload->do_filename_check = "n";
      if ($foto_upload->upload())
         {
         $foto_upload->process_image(false, true, true, 80);
         $foto_upload->message[] = "Processed foto: ".$foto_upload->file_copy."!"; // "file_copy is the name of the foto"
         }
      }
   }
$error = $foto_upload->show_error_string();
?>

you don't need to build an array, just number the names to make them unique (it's easier)

the error is because there is no filename submitted
