Here is a simple cart, but should give you the idea.
Cheers!
-J
<?
switch($action) {
# Add to cart
case 'add':
$_SESSION['cart'][$id] = array('name'=>$name,'price'=>$price,'qty'=>$qty);
break;
# Remove from cart
case 'remove':
# Remove item
unset($_SESSION['cart'][$id]);
break;
}
# Show cart contents if any
if (count($_SESSION[cart]) > 0) {
print "Cart contents:";
foreach($_SESSION[cart] as $id => $value) {
print "<li> $value[qty] $value[name] (@\$$value[price])<br>";
$total += $value[price] * $value[qty];
}
print "Total: \$$total<hr><br>";
}
# a product
$id = 101; $name = 'beer'; $price = '3.15';
?>
<form action="<?=$PHP_SELF?>">
<p>Qty: <input type="textbox" name="qty" size=3 value="1"><br>
Product: <?=$name?><br>
Price: $<?=$price?> NZD<br>
<input type="radio" name="action" value="add" checked> Add
<input type="radio" name="action" value="remove"> Remove
<input type="submit" value="OK">
</p>
<input type="hidden" name="id" value="<?=$id?>">
<input type="hidden" name="name" value="<?=$name?>">
<input type="hidden" name="price" value="<?=$price?>">
</form>
?>
