  Try the following:
  
  

  Code

  $rc = FileUtil::uploadFile ('filekey', 'some/directory');

  
  
  where filekey is the name under the $_FILES array which contains the reference to the file you want to upload.
  
  As for generating thumbnails (or just resizing the image), you will have to write some custom code which calls the Thumbnail module.
  
  Greetings

  This is a sketch of how the code should look like:
  

  Code

  $rc = FileUtil::uploadFile ('uploadkey', $path.$name);
  
  $image = array();
  $image['srcFilename']   = $path.$name;
  $image['dstFilename']   = $path.$newname;
  $image['w'] = $width;
  $image['h'] = $height;
  
  pnModAPIFunc('Thumbnail', 'user', 'resizeImage', $image);

  
  
  Basically srcFilename must be the path to the image u just uploaded, dstFilename must be the path (and name) where u want to save the resized image, w and h are the sizes of the image after the resizing.
  
  Please note that Thumbnail doesn't work out of the box but need a little bit of configuration.

  What kind of configuration? I tried to get it to work with Pagesetter documents, which have query style URLs rather than actual paths, and it wouldn't work. However the underlying utility it uses does this just fine. I was thinking maybe it was a bug in the Zikula module portion of it, but maybe I have missed some configuration?

  What kind of configuration?

  
  
  IIRC in modules/Thumbnail/includes/phpThumb/ you have to rename phpThumb.config.php.default to phpThumb.config.php
  based on the configuration of your server you may also need to change some settings

  sorry, there was an error in my previous code, the right one is:
  

  Code

  $rc = FileUtil::uploadFile ('uploadkey', $destination, $name);

  
  in your case $destination should be
  

  Code

  $destination = "modules/test/uploads/";

  
  
  
  

  msshams

  2- if fileUtil encounter with an error, how can i read that? i echo $RC but it doesn't any value.

  
  
  $RC is a boolean value, because the function move_uploaded_file returns true or false.
  Unfortunately the reason of the failure is issued with a warning, so you have to find out yourself what went wrong (check that the destination folder is writable)
  
  BTW I opened a ticket suggesting to improve the output of FileUtil::uploadFile();

  It looks like there is a problem with the file you are uploading, because there is this error:
  
  

  Code

  setSourceFilename(modules/RoseateMem/portrait/25.png) set $this->sourceFilename to "modules/RoseateMem/portrait/25.png" in file "phpthumb.class.php" on line 243
  
    file_exists() = 0 in file "phpthumb.class.php" on line 1099
  
  is_executable() = 0 in file "phpthumb.class.php" on line 1100

  
  
  file_exists() = 0 means that the file does not exist. Are you sure that the file has been uploaded? if you look in the folder modules/RoseateMem/portrait/ is the file 25.png there?

  BTW I just noticed that what I told you before was not 100% correct. The variable $RC is not boolean, but still it's not really reliable because it covers only few errors. If it contains an error it means that the upload failed, but if it's empty it doesn't mean the the upload was fine. For example if it fails to upload the file (technically it just moves it) because the destination folder is not writable it fails without any error.
  
  So basically it's fine to check it, just be aware that in some situations it fails without telling you that it happened.
  
  What you can do is to add this lines:
  

  Code

  if (!file_exists("modules/RoseateMem/portrait/".$memberinfo['pid'].".png")) {
      // upload failed, do something
  }

  
  after:
  

  Code

  $rc = FileUtil::uploadFile ('pic', 'modules/RoseateMem/portrait',$memberinfo['pid'].".png");

  
  
  By this way you can be sure that the upload succeeded, and if it didn't you can return an error message or whatever

  yes, it's uploaded. i changed code to this: http://paste.ubuntu.com/269604/
  also when i see content of 'portrait' folder i see uploaded pictures. do you have another idea? thank you again for your replies.

  this code is wrong, you have to add an exclamation point before file_exists
  what you want to do is something like "if the file does not exist then exit", but if you omit the exclamation point you obtain "if the file exists then exit"
  
  anyways, if you correct the script (adding the !) and try to upload the image what happens?
  do you still get the error message of Thumbnail? Same as before?

  thank you. i changed my code to this, but still 'ERROR' doesn't echo.
  
  Loader::loadClass('FileUtil');
  $RC = FileUtil::uploadFile ('pic', 'modules/RoseateMem/portrait',$memberinfo['pid'].".png");
  
  if (!file_exists("modules/RoseateMem/portrait/".$memberinfo['pid'].".png")) {
  echo "error";
  exit;
  }

  Are you sure that Thumbnail is correctly configured? Check the administration page, if there is a problem with the module it should be written there.
  
  Also, have you moved the website from a server to another? Or from localhost to a live webserver?
  If it's like I'd like to investigate the problem personally
