here is a very simple cart in sessions. you have stockno and quan, it can be
easily modified to handle various other variables.
<?php
class cart
{
function add($product_id, $product_quan = 1)
{
if ($product_quan < 1)
$product_quan = 1;
$this->cart_product_id[$product_id] = $product_id;
$this->cart_product_quan[$product_id] = $product_quan;
}
function add_single($var_name)
{
if ( !isset($GLOBALS[$var_name]) )
return ;
$this->add($GLOBALS[$var_name], 1);
}
function add_multiple($var_name)
{
if ( !isset($GLOBALS[$var_name]) )
return ;
foreach($GLOBALS[$var_name] as $pos => $val)
$this->add($pos, $quan);
}
function delete($product_id)
{
unset($this->cart_product_id[$product_id]);
unset($this->cart_product_quan[$product_id]);
if ( !count($this->cart_product_id) )
{
unset($this->cart_product_id);
unset($this->cart_product_quan);
}
}
function delete_multiple($var_name)
{
if ( !isset($GLOBALS[$var_name]) )
return ;
foreach($GLOBALS[$var_name] as $pos => $val)
$this->delete($pos);
}
function update($product_id, $product_quan)
{
if ($product_quan < 1)
$product_quan = 1;
$this->cart_product_id[$product_id] = $product_id;
$this->cart_product_quan[$product_id] = $product_quan;
}
function update_multiple($var_name)
{
if ( !isset($GLOBALS[$var_name]) )
return ;
foreach ($GLOBALS[$var_name] as $pos => $val)
$this->update($pos, $val);
}
}
$cart = new cart;
if (!isset($HTTP_SESSION_VARS['cart']))
{
$cart = new cart();
session_register('cart');
}
?>
