Processing files in HTML_QuickForm


Can someone explain how to check if a file has been uploaded and then store that file in a folder using HTML QuickForm?

I'm not sure what teh syntax is to use with isUploadedFile() and moveUploadedFile().

Thankyou.  I've seen that page, and unfortunately it doesn't have any info about processing files.  What I want to do is to check if a file has been uplaoded, check the file type, rename it and then move it to a folder (which may need to be created if it does not exist).  I haven't been able to find any information on how to do this.

Surprised! check the code snippet
$form = new HTML_QuickForm('uploader');
// File upload needs an element of type "file"
$form->addElement('file','uploaded_file','Your File:');
// We want files of 128kbytes or less
$max_size = 131072;
// Make sure that a file is uploaded
$form->addRule('uploaded_file','Please upload a file','uploadedfile');
// Have HTML_QuickForm test, after the file is uploaded, that it is
// less than 128k
$form->addRule('uploaded_file','Your file is too big','maxfilesize',$max_size);
$form->addElement('submit','save','Send It');
// Tell well-behaved browsers not to allow upload of a file larger than
// 128k
// Display or process the form
if ($form->validate()) {
} else {
function move_file($data) {
  global $form;
// Remove backslashes and forward slashes from new filename
$new_name = strtr($data['uploaded_file']['name'],'/\\','');
// Remove ".." from new filename
$new_name = str_replace('..','',$new_name);
$file =& $form->getElement('uploaded_file');
if ($file->moveUploadedFile('/tmp',$new_name)) {
  print "The file has been uploaded to /tmp/$new_name.";
} else {
  print "The file could not be uploaded to /tmp/$new_name.";

Thanks, this looks very useful.  I will test it out when I have time later this afternoon.  Just one other thing - uploading a file is optional for the form I am creating.  To test for an uploaded file - is this syntax correct?

$file =& $form->getElement('uploaded_file'){
if ($file->isUploadedFile){
    //do stuff
I think your code should work.

Just see the line 36 of my code snippet
