Hello, I am working on a site and I need some guidance please. I have a form that I would like to store two values in a session. All I need is the product and the quantity. Now I get the product from the form fields – size, color, logo, and voltage using a switch/case. And I get the quantity from the form field quantity. I would like to store these values in a session variable and be able to go back and add to, delete, or edit the variable.

My goal is to be able to figure out what products and quantity the client needs. Then send email order to the warehouse for processing. I am having trouble storing the value and adding to it, whenever I go back and use the form the only output I get is the current values. It over writes the old data. If you want to visit what I have now you can see it at (http://www.rediheat.com/feb2008/order.php?f=single_pie) the only form working now is single_pie Any Help?

 

here is my code:

<?php include 'includes/header.inc';  ?>

<table width="887" border="0" align="center" cellpadding="0" cellspacing="0">

      <tr>

        <td valign="top"><img src="images/spacer.gif" width="880" height="1"></td>

        <td rowspan="2"><img src="images/spacer.gif" width="7" height="466"></td>

      </tr>

      <tr>

      <!-- This is where the ordering form will be placed -->

        <td valign="top" class="product_article" style="background-image:url(images/order_page_bg.jpg); background-repeat:no-repeat; ">

        <div style="padding-left:14px; padding-top:10px; ">

        <!-- This area is where the include files will be  -->

<?php 
            $allowed_inc = array('single_pie', 'multi_pie', 'food_service', 'element'); 
             
                         
            if (isset($_POST['single_pie_submit'])) { // THIS IS WHERE THE PRODUCTS WILL BE ADDED TO THE DATABASE 
            require_once ('connection/mysql_connect.php'); // Connect to the database. 
            $error_message = ""; 
             
               if ($size != "blank") { 
                  $size = $_POST['size'];   
               } else { 
                  $error_message .= "<p>You forgot to enter a size</p> "; 
               } 
               if ($color != "blank")  { 
                  $color = $_POST['color']; 
               } else { 
                  $error_message .= "<p>You forgot to choose a color!</p> "; 
               } 
               if ($logo!= "blank") { 
                  $logo = $_POST['logo']; 
               } else { 
                  $error_message .= "<p>You need to choose if you would like a logo on your bag </p> "; 
               } 
               if ($voltage!= "blank") { 
                  $voltage = $_POST['voltage']; 
               } else { 
                  $error_message .= "<p>You did not choose the electrical voltage that you require </p>"; 
               } 
               if ($quantity != "") { 
                  $quantity = $_POST['quantity']; 
               } else { 
                  $error_message .= "<p>You did not select a quantity </p>"; 
               } 
                            
               if (strlen($error_message) > 1) { // IF THERE WAS AN ERROR 
                  echo $error_message . "<p>Click <a href='javascript:history.back()'>here</a> to go back</p>"; 
                  echo "</div>

The other user had pointed out that I did not put the PHP in tags and that it was hard to read. So I marked the other one as solved and posted the topic with the PHP in tags. I did not see a way to edit the original post or I would have put the tags around the original. If you know a way of editing the original, I would be happy to put that in quotes.
