Multiple Image upload and resize

Recommended Posts

hello. I am working on a multiple image upload and resizing system. I have found a code online that does exactly as I want!!!! I am now trying to get it to insert into my database properly, which is where I need help at. I have two tables, an items and an images table. I want the item table to only insert once, while I want the images table to insert all the files and their new name that the code creates. The first few lines are the insert code, and the after is the upload/resize code. any help on this is greatly appreciated.

$title = $_POST['title'];

$des = mysql_real_escape_string($_POST['description']);
$price = mysql_real_escape_string($_POST['price']);
$qty = mysql_real_escape_string($_POST['quantity']);
$cat2 = mysql_real_escape_string($_POST['category2']);
$cat = mysql_real_escape_string($_POST['category']);


if ($cat2 !='')
{$cat = $cat2; }

mysql_query("INSERT INTO items (id, name, price, description, quantity, category_id)
VALUES ('$id123', '$title', '$price','$des', '$qty', '$cat')");
if($cat2 !=''){
mysql_query("INSERT INTO categories (category)
VALUES ('$cat2')");

mysql_query("INSERT INTO images (item_id, image)
VALUES ('$id123', 'images/".$NewImageName."')");
 }
foreach($_FILES as $file)
{

// some information about image we need later.
$ImageName      = $file['name'];
$ImageSize      = $file['size'];
$TempSrc        = $file['tmp_name'];
$ImageType      = $file['type'];


if (is_array($ImageName))
{
   $c = count($ImageName);

   echo  '<ul>';

   for ($i=0; $i < $c; $i++)
   {
       $processImage           = true;
       $RandomNumber           = rand(0, 9999999999);  // We need same random name for both files.

       if(!isset($ImageName[$i]) || !is_uploaded_file($TempSrc[$i]))
       {
           echo '<div class="error">Error occurred while trying to process <strong>'.$ImageName[$i].'</strong>, may be file too big!</div>'; //output error
       }
