PHP Shopping Basket

[dachshund]

Hey,

 

I'm having some problems getting my store website to show the contents of a shopping cart.

 

At the moment all the IDs of the items that have been added to the basket are being stored as $basket = $_SESSIONS['basket'].

 

This is the function I have to show those items, but it's not showing up anything. Can anywhere see the problem or offer some help?

 

Thanks

 

function showBasket() {
$basket = $_SESSION['basket'];
if ($basket) {
	$items = explode(',',$basket);
	$contents = array();
	foreach ($items as $item) {
		$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
	}
	$output[] = '<form action="basket.php?action=update" method="post" id="basket">';
	$output[] = '<table>';
	foreach ($contents as $id=>$qty) {
		$sql = 'SELECT * FROM store WHERE id = '.$id;
		$result = $db->query($sql);
		$row = $result->fetch();
		extract($row);
		$output[] = '<tr>';
		$output[] = '<td><a href="basket.php?action=delete&id='.$id.'" class="r">Remove</a></td>';
		$output[] = '<td>'.$title.' by '.$author.'</td>';
		$output[] = '<td>£'.$price.'</td>';
		$output[] = '<td><input type="text" name="qty'.$id.'" value="'.$qty.'" size="3" maxlength="3" /></td>';
		$output[] = '<td>£'.($price * $qty).'</td>';
		$total += $price * $qty;
		$output[] = '</tr>';
	}
	$output[] = '</table>';
	$output[] = '<p>Grand total: <strong>£'.$total.'</strong></p>';
	$output[] = '<div><button type="submit">Update basket</button></div>';
	$output[] = '</form>';
} else {
	$output[] = '<p>You shopping basket is empty.</p>';
}
return join('',$output);
}
