Here is a script to allow multiple uploads it works just as well for single. Make sure to CHMOD the upload directory to 777.
//Upload form
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
// Change the name of the files into an array
<input type="file" name="usrfile[]">
</form>
</body>
</html>
// upload.php
<?php
$c = count ($_FILES ['usrfile'] ['name']);
for ($i = 0; $i < $c; $i++) {
$usrfile_name = $_FILES['usrfile']['name'][$i];
$usrfile_tmp = $_FILES['usrfile']['tmp_name'][$i];
$location = "/file/upload/dir/ .$usrfile_name";
move_uploaded_file ($usrfile_tmp, $location);
}
?>
