<?php 
// This block grabs the whole list for viewing
$product_list = "";
$sql = mysql_query("SELECT * FROM product 
           ORDER BY date_added DESC");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
  $product_list .= "<table><tr><td>Product ID</td><td>Items</td><td>Price</td><td>Date</td><td>Action</td></tr>";
  
  while($row = mysql_fetch_array($sql)){
             $id = $row["id"];
       $product_name = $row["name"];
       $details = $row["details"];
       $size = $row["size"];
       $price = $row["price"];
       $quantity = $row["quantity"];
       $date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
       $product_list .= "<tr><td>$id</td>
