I found a nice upload script with a progress bar. But unfortunately it will not work for me:( I always get an error: Undefined index: file1 in C:\wamp\www\upload\upload_parser.php on line 7. I spend already a couple hours to get rid of it with any success. But the script supposed to work. Does anyone has an idea why I get this error? (FYI: I downloaded it from http://www.developphp.com/view.php?tid=1351) I already checked php.ini. A print_r of $_Files shows me an empty error. I read something about that it isn't possible to upload images via Ajax. But the script works for other users. Totally weird.
I appreciate every hint. Thank you very much in advanced.

And the upload_parser.php file:
<?php
print_r($_FILES);
$fileName = $_FILES["file1"]["name"];
$fileTmpLoc = $_FILES["file1"]["tmp_name"];
$fileType = $_FILES["file1"]["type"];
$fileSize = $_FILES["file1"]["size"];
$fileErrorMsg = $_FILES["file1"]["error"];
if (!$fileTmpLoc) {
echo "ERROR! Please browse for a file before clicking the upload button.";
exit();
}
if (move_uploaded_file($fileTmpLoc, "uploads/$fileName")) {
echo "$fileName upload is complete";
}
else {
echo "move_uploaded_file function failed";
}
?>
