spiderman_2k7 Posted December 9, 2007 Share Posted December 9, 2007 Hi. I am creating a simple PHP ordering system where a user can purchase items and then 'buy' them. I was having problems totalling the prices up of all the items a user 'purchased' until I came accross using sessions. I adopted this in to my PHP and once a submit button is pressed a new page opens displaying the price of the item without VAT and a price with VAT, which is what my aim is. However, the problem is that I need my system to allow a user to purchase one OR more items. At the moment I can only get a user to purchase one item with sessions, is it possible to have a user purchase more then one item? Here are my codes: Page listing items for 'sale' - <html> <head> <title>Football Shirts 'R' Us</title> </head> <body> <body bgcolor="#339900"> <p> <font size=16, color=white><b><u><center>Football Shirts 'R' Us!</center></u></b></p> <form action="/showvariables3.php" method="post"> <br> <table width=45%, border=1, align=center> <tr> <th> ID </th> <th> Football Shirt </th> <th> Team </th> <th> Price </th> <th> Select </th> </tr> <tr><tr> <?php if(!($lines = file('read_shirts.txt'))) {echo 'ERROR: Unable to open file! </body></html>'; exit;} foreach($lines as $theline) { list($id, $shirt, $club, $price) = split('\|',$theline); ?> <tr> <td><? echo $id; ?></td> <td><? echo $shirt ?></td> <td><? echo $club ?> </td> <td>£<? echo $price ?> </td> <td> <form method="post" action="addtocart.php" > <input name="id" type="hidden" value="<?php echo $id; ?>"> <input name="price" type="hidden" value="<?php echo $price; ?>"> <input type="submit" value="Submit"> </form> </td> </tr> <?php } ?> </table> </body> </html> Cart - <? session_start(); // start the session $id = $_POST["id"]; // get the id $price = $_POST["price"]; // get the price if ( !isset( $_SESSION["cart"] ) ) { // check if the array is there $_SESSION["cart"] = array(); // if not create one } $_SESSION["cart"][$id] = $price; // add the data to the array header("location:showvariables3.php"); // redirect to the cart page ?> Order summary page - <html> <head> <title>Football Shirts 'R' Us!</title> </head> <body bgcolor="green"> <p> <font size=12, color=white><b><u><center>Your order with Football Shirts 'R' Us</center></u></b></p></font> <p><font size=6, color=white>Hello, your order is as follows:</p></font> <table> <tr> </tr> <?php session_start(); $session = $_SESSION['cart']; $count = count($session); if($count==0){ echo "No Items In Cart"; } else { ?> <html> <head> <title>Football Shirts 'R' Us!</title> </head> <body bgcolor="green"> <p> <font size=12, color=white><b><u><center>Your order with Football Shirts 'R' Us</center></u></b></p></font> <p><font size=6, color=white>Hello, your order is as follows:</p></font> <table> <tr> </tr> <?php foreach ($_SESSION['cart'] as $id => $price ) { $sub[]=$price; echo $id; echo " - "; echo $price; echo "<br>"; } ?> <br> <tr> <td aliign='left'> Total Excluding VAT: </td> <td nowrap> £<?php $subtotal = array_sum($sub); echo number_format($subtotal, 2, '.', ','); $total = $subtotal /100 * 17.5 ; $total = $total + $subtotal; $total = round($total, 2); ?> </td> </tr> <br> <tr> <td align='left'> Total Including VAT: </td> <td nowrap>£<? echo number_format($total, 2, '.', ','); ?></td> </tr> </table> </body> </html> <? } ?> </table> </body> </html> Thanks Quote Link to comment Share on other sites More sharing options...
revraz Posted December 9, 2007 Share Posted December 9, 2007 You can either make the session a multi dimensional array or create more session variables for each item. Quote Link to comment Share on other sites More sharing options...
spiderman_2k7 Posted December 9, 2007 Author Share Posted December 9, 2007 How would I go about doing either of these? Could you edit it for me please, or provide further details? Many thanks Quote Link to comment Share on other sites More sharing options...
