CART TO PAYPAL

[ievernova]

Hi,

I m trying to export a cart script into paypal, for paypal to understand that ive sent multiple items i need to give each product in the array a number starting from one going up in numberical order,

iv tried to use a for loop with an increment counthing variable for($counter=1;$counter>0;$coutner++) but cant get it to work with this existing code; whats the easiest way to do this?! i know how to get all of the variables and stuff into the form i need to send to paypal so i would just like to know how to output the number from a variable where it says in teh code below...

 

i want the final output to be something like this

                       

1 ProductA Quantity: 20

2 ProductB Quantity: 15

3 ProductC Quantity: 6

 

this is the point at which i output the cart before proceeding to the checkout,

 

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>';
        
        foreach ($contents as $id=>$qty) 
            {
            $sql = 'SELECT * FROM syn_vinyl_product WHERE prod_id = '.$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>';
            $output[] = '<td>'.$prod_title.' by '.$prod_desc.'</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>';
            $output[] = '<td>//////////    OUTPUTT THE NUMBER HERE  /////////////</td>';
            
            $total = '';
            $total += $price * $qty;
            
            $output[] = '</tr>';
            }
            
        $output[] = '</table>';
        $output[] = '<p>Grand total: <strong>£'.$total.'</strong></p>';
        $output[] = '<div><button type="submit">Update cart</button></div>';
        $output[] = '</form>';
    }  

 

THANKS ALOT!!!
