I am trying to convert some webcode and am having trouble. I have a website with an admin section allowing me to upload images one at a time and am trying to change it to allow me to upload multiple images at once. I must have something out of place that is making this fail.

echo "<span class=\"adminHeader\">Image Gallery Administration</span><br /><br />";

IF ($do == "addImage") {

echo "<span class=\"actionHead\">Add an Image</span><br /><br />";

$page=$_GET['page'];
if(isset($_FILES['files'])){
    //$errors= array();
    foreach($_FILES['files']['tmp_name'] as $key => $tmp_name ){
$descriptionPost = addslashes($_POST['description']);
$albumPost = addslashes($_POST['album']);
$image = $_FILES['theImage[]']['name'];

if($page=="submit"){$error = chkGalleryElements($image,$albumPost,$descriptionPost);}

    IF (($page=="submit")&&($error=="5")){

    $maxfilesize = 5000000;

    $query = "SELECT MAX(iid) FROM gallery";
    $result=mysql_query($query, $connection) or die("Query failed : " . mysql_error());
    $maxImageId = max(mysql_fetch_array($result)); 
    IF ($maxImageId==null){
    $maxImageId=0;
    }

    $imageName = $maxImageId + 1;

    $uploadfile = "$uploaddir$imageName.jpg";
    $uploadTHfile = $uploadTHdir."th_".$imageName.".jpg";
    $uploadsize = $_FILES['theImage']['size'];

    /*== get file extension (fn at bottom of script) ==*/
    /*== checks to see if image file, if not do not allow upload ==*/

    $pext = getFileExtension($image);
    $pext = strtolower($pext);
    if (($pext != "jpg")  && ($pext != "jpeg")) {
        print "<h1>ERROR</h1> The file you uploaded had the following extension: $pext.<br>";

Take al look at the stucture of the $_FILES - variable. (scroll down about 3/4)
basicly use like $_FILES['theImage']['tmp_name'][$index]
