since this is the line where the name is used

if(move_uploaded_file($_FILES["file"]["tmp_name"][$key], $upload_dir.$filename)){

you can just add it in all this stuff

$filename = explode(".", $_FILES["file"]["name"][$key]);
$filenameext = $filename[count($filename)-1];
unset($filename[count($filename)-1]);
$filename = implode(".", $filename);
$filename = substr($filename, 0, 15).".".$filenameext;

is there something specifically going wrong or did you not know how to add it?

on this line

$filename = substr($filename, 0, 15).".".$filenameext;

assuming $filename has already been stripped of it's extension, try doing something like:

$today = getdate();
$uniqueStr = $today[year];
$uniqueStr .= $today[mon];
$uniqueStr .= $today[wday];
$uniqueStr .= $today[mday];
$uniqueStr .= $today[hours];
$uniqueStr .= $today[minutes];
$uniqueStr .= $today[seconds];
$filename = substr($filename, 0, 15).$uniqueStr.".".$filenameext;

pardon the longhand above

then your line of

if(move_uploaded_file($_FILES["file"]["tmp_name"][$key], $upload_dir.$filename)){
echo("File uploaded successfully. - <a href='/is/img/".$filename."' target='_blank'>".$filename."</a><br />");
}

should work and the filename will be the original with timestamp inside follwed by the extension.

Hope this helps
