Help with adding sizes to cart page

PHP
1

hello everyone,
I’ve been racking my brain with this…
I’m trying to display the sizes of shirts when added to my cart.
The sizes come from a select menu.
The sizes show up in the cart, but overwrite the last size added.

For example …
add shirt1 size-small
add shirt2 size-medium

the cart displays…
shirt 1 size-medium
shirt 2 size-medium

Can you please help me so when I add a new item it doesn’t overwrite the previous size.

all help is appreciated

my code is as follows…

selection from my product page

<select name="shirt_size">
<option value="x-small">x-small</option>
<option value="small">small</option>
<option value="medium">medium</option>
<option value="large">large</option>
</select>

code that displays shirt size

$output[] = '<td>'.$_POST['shirt_size'].'</td>';

function displaying my cart

function showCart() {
	global $db;
	$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>';
			// start div
			$output[] = '<div id="cart_table">';
			//
			$output[] = '<tr>';
			$output[] = '<td><h4>Product</h4></td>';
			$output[] = '<td><h4>Item No.</h4></td>';
			$output[] = '<td><h4>Price</h4></td>';
			$output[] = '<td><h4>Size</h4></td>';
			$output[] = '<td><h4>Quantity</h4></td>';
			$output[] = '<td><h4>Price Total</h4></td>';
			$output[] = '<td><h4>&nbsp;</h4></td>';
			$output[] = '</tr>';
			//new row
		foreach ($contents as $product_id=>$qty) {
			$sql = 'SELECT * FROM products WHERE product_id = '.$product_id;
			$result = $db->query($sql);
			$row = $result->fetch();
			extract($row);
			//
			$output[] = '<tr>';
			$output[] = '<td><a href="product.php?product_id='.$product_id.'">'.$product_title.'</a></td>';
			$output[] = '<td>'.$product_plu.'</td>';
			$output[] = '<td>$'.$product_price.'</td>';
			//
			$output[] = '<td>'.$_POST['shirt_size'].'</td>';
			//
			$output[] = '<td><input type="text" name="qty'.$product_id.'" value="'.$qty.'" size="3" maxlength="3" /></td>';
			$output[] = '<td>X&nbsp;$'.($product_price * $qty).'</td>';
			$total += $product_price * $qty;
			$output[] = '<td><a href="cart.php?action=delete&product_id='.$product_id.'" class="r">Remove</a>&nbsp;</td>';
			$output[] = '</tr>';
			//end div
			$output[] = '</div>';
			
			
			
		}
		$output[] = '</table>';
		$output[] = '<p>Grand total: <strong>$'.$total.'</strong></p>';
		$output[] = '<div class="float-right"><button type="submit">Update cart</button>';
		$output[] = '</form>';

sorry bout that


session_start();
// Process actions
$cart = $_SESSION['cart'];
$action = $_GET['action'];
switch ($action) {
	case 'empty':
		if($cart) {
			unset($cart);
		}
		break;
	case 'add':
		if ($cart) {
			$cart .= ','.$_GET['product_id'];
		} else {
			$cart = $_GET['product_id'];
		}
		break;
	case 'delete':
		if ($cart) {
			$items = explode(',',$cart);
			$newcart = '';
			foreach ($items as $item) {
				if ($_GET['product_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')) {
				$product_id = str_replace('qty','',$key);
				$items = ($newcart != '') ? explode(',',$newcart) : explode(',',$cart);
				$newcart = '';
				foreach ($items as $item) {
					if ($product_id != $item) {
						if ($newcart != '') {
							$newcart .= ','.$item;
						} else {
							$newcart = $item;
						}
					}
				}
				for ($i=1;$i<=$value;$i++) {
					if ($newcart != '') {
						$newcart .= ','.$product_id;
					} else {
						$newcart = $product_id;
					}
				}
			}
		}
	}
	$cart = $newcart;
	break;
}
$_SESSION['cart'] = $cart;

Okay… you’re not storing size information in the cart. Only thing you’re storing is the product ID. So the system doesnt know what size the person ordered.

I tried this… but I still can’t get it right.
Any idea what I’m doing wrong?


 case 'add':
        if ($cart) {
            $cart .= ','.$_GET['product_id']['shirt_size'];
        } else {
            $cart = $_GET['product_id']['shirt_size'];
        }
        break;
