[SOLVED] I want to add multiple items to a shopping cart at the same time.

Hi Guys..
I am setting a shopping cart and it works OK with BUY NOW buttons and adds the product to the cart one at a time.

However, I want to select a few items, via checkboxes, and pass them to the cart.php all at the same time. The shopping cart has facility to change the quantities and update the cart.

This is a chopped down version of the sending code:

Code:

		$main_content .= "<form action='cart/cart.php?action=add&id=$id' method='get' target='new'>";
		if($color==1){
		$main_content .= "<tr bgcolor='#ffcc99'>";
// ORDERS 1
		$main_content .= "<td valign='top'>$product <font color=#ff0000><b>$comments</b></font></td>";
		$main_content .= "<td valign='top'>$packquantity</td>\n";
		$main_content .= "<td valign='top'>&pound$trade</td>\n";

		$main_content .= "<td valign='top'><input type='checkbox' name='id' value='$id'>\n";
 
		$main_content .= "</tr>\n";


		$main_content .= "<input type='submit' value='Place Order'>";
		$main_content .= "&nbsp;&nbsp;&nbsp;&nbsp;<input type='reset' value='Clear'>";

		$main_content .= "</form></form></td></tr></table>\n";

The receiving code in my cart.php file is:

Code:

$cart = $_SESSION['cart'];  
$action = $_GET['action'];  

switch ($action) {  
    case 'add': 
        if ($cart) {  
            $cart .= ','.$_GET['id'];  
        } else {  
            $cart = $_GET['id'];  
        }  
header("Location: cart.php"); 
        break;

I think that the receiving code is wrong. It works OK for the BUY NOW button, one at a time, but it doesn't work for multiple additions.

Can anybody help ???

Thanks,

John C

One suggestion is to use arrays for your checkboxs. Here is a simple example:

Hi michaelk..

Thank for your suggestion.
I had already changed to using arrays by adding [] after 'name = 'id'
It now reads:

Code:

$main_content .= "<td valign='top'><input type='checkbox' name='id[]' value='$id'>\n";

At the receiving end, cart.php, when I use:

Code:

print_r ($_POST['id']);
exit;

I get all the values of the array.

It is this next part where I get stuck.
My cart.php is:

Code:

switch ($action) {  
    case 'add':  
        if ($cart) {  
            $cart .= ','.$_GET['id'];  
        } else {  
            $cart = $_GET['id'];  
        }  
header("Location: cart.php"); 
        break;

and it doesn't handle the array.
This is where I need the help.

You need to loop through the array and suggest using a foreach loop similar to this thread.
