My Shopping Cart

Post by pieterse22 »

Hi Everyone,
Can someone please help me. I have developed a shopping cart and it works fairly well, providing single items are placed in the cart. What I cant get to work is some of my single items comprises of many colors and I cant get the code to work proparly.
Either it will include colors for items that does not have products and when you update the Quantities, the color selection dissapears. I have enclosed my origional code. Please help. It will be mutch appreciated.
Regards,
John.
Herewith my origional code without the provision for the different colors. Some of the items is balloons and I would like to give a color choice in these items.

Code: Select all

function showCart() {
	global $db;
	$total = 0;
	$cart = $_SESSION['cart'];
	if ($cart) {
		$items = explode(',',$cart);
		$contents = array();
		foreach ($items as $item) {
			$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
		}
		$output[] = '<form action="cart.php?action=update" method="post" id="cart">';
		$output[] = '<table>';
		foreach ($contents as $id=>$qty) {
			$sql = 'SELECT * FROM products WHERE id = '.$id;
			$result = $db->query($sql);
			$row = $result->fetch();
			extract($row);
			$output[] = '<tr>';
			$output[] = '<td><a href="cart.php?action=delete&id='.$id.'" class="r">Remove</a></td>';
			$output[] = '<td>'.$title.'</td>';
			$output[] = '<td>&pound;'.$price.'</td>';
			$output[] = '<td><input type="text" name="qty'.$id.'" value="'.$qty.'" size="3" maxlength="3" /></td>';
			$output[] = '<td>&pound;'.($price * $qty).'</td>';
			$total += $price * $qty;
			$output[] = '</tr>';
		}
		$output[] = '</table>';
		$output[] = '<p>Grand total: <strong>&pound;'.$total.'</strong></p>';
		$output[] = '<div><button type="submit">Update cart</button></div>';
		$output[] = '</form>';
	} else {
		$output[] = '<p><h1>Your shopping cart is empty.</h1></p>';
	}
	return join('',$output);
}
?>
Together with the following script in my Cart

Code: Select all

<?php
// Include MySQL class
require_once('inc/mysql.class.php');
// Include database connection
require_once('inc/global.inc.php');
// Include functions
require_once('inc/functions.inc.php');
// Process actions
@$cart = $_SESSION['cart'];
@$action = $_GET['action'];
switch ($action) {
	case 'add':
		if ($cart) {
			$cart .= ','.$_GET['id'];
		} else {
			$cart = $_GET['id'];
		}
		break;
	case 'delete':
		if ($cart) {
			$items = explode(',',$cart);
			$newcart = '';
			foreach ($items as $item) {
				if ($_GET['id'] != $item) {
					if ($newcart != '') {
						$newcart .= ','.$item;
					} else {
						$newcart = $item;
					}
				}
			}
			$cart = $newcart;
		}
		break;
	case 'update':
	if ($cart) {
		$newcart = '';
		foreach ($_POST as $key=>$value) {
			if (stristr($key,'qty')) {
				$id = str_replace('qty','',$key);
				$items = ($newcart != '') ? explode(',',$newcart) : explode(',',$cart);
				$newcart = '';
				foreach ($items as $item) {
					if ($id != $item) {
						if ($newcart != '') {
							$newcart .= ','.$item;
						} else {
							$newcart = $item;
						}
					}
				}
				for ($i=1;$i<=$value;$i++) {
					if ($newcart != '') {
						$newcart .= ','.$id;
					} else {
						$newcart = $id;
					}
				}
			}
		}
	}
	$cart = $newcart;
	break;
}
$_SESSION['cart'] = $cart;
?>
