hi,
im pretty new with PHP. im busy buiding an onlineshop, im pretty far with the site the only things is that im now stuck with the shopcart...
what i try to accomplish is that a user can add products as much as he/she wants. When a user adds a product i store the id and qty in a session. When i they continue shopping i want to add the new product under/above the existing one.
as long as the user dont check out, i will want to keep the products in the sesion (has this format $_SESSION['winkelwagen']['products']['pid']=$pid😉
Adding this first product is no problem, when i update and/or add a new product it override the first product plus twice.
So at this point im lost, i hope somebody can help me out on this one,
here beneath is the code and form im using.
thanks a mil
<?php
if(isset($_SESSION['winkelwagen']))
{
//query for new to be added product
$_SESSION['winkelwagen']['products']['pid']=$pid //($pid from db,added to the session)
$winkelwagen=$_SESSION['winkelwagen']
if(is_array(winkelwagen)
{
foreach(winkelwagen as $prodid=>$qty) //begin foreach
{
//check to see if a product is already added
if($prodid != $pid)
{
//add new product to Session
}
else
{
update quantity
}
?>
<tr>
<input type="hidden" name="pid[]" value="<?php echo $pid;?>">
