When I have an item in the cart, and update it to qty 0 it gets deleted.
When I have multiple items in the cart, and update all to any quantity besides zero, all are updated correctly.
When I have multiple items in the cart, and update all to qty 0, one is left behind, and qty isn't changed.
Controller method handling the update:
Code:
public function update()
{
// for each item in the cart
for ($i = 1; $i <= $this->cart->total_items(); $i++)
{
$item = $this->input->post($i);
// if the posted qty value is a number
if(is_numeric($item['qty']))
{
// set cart update array
$data[$i] = array(
'rowid' => $item['rowid'],
'qty' => $item['qty']
);
}
// update the cart
$this->cart->update($data);
}
$this->_display();
}
MY_Cart.php
Code:
<?php
class MY_Cart extends CI_Cart {
function MY_Cart($params = array())
{
// Are any config settings being passed manually? If so, set them
$config = array();
if (count($params) > 0)
{
foreach ($params as $key => $val)
{
$config[$key] = $val;
}
}
// Grab the shopping cart array from the session table, if it exists
if (isset($_SESSION['cart_contents']))
{
$this->_cart_contents = $_SESSION['cart_contents'];
}
else
{
// No cart exists so we'll set some base values
$this->_cart_contents['cart_total'] = 0;
$this->_cart_contents['total_items'] = 0;
}
log_message('debug', "Cart Class Initialized");
}
function _save_cart()
{
// Unset these so our total can be calculated correctly below
unset($this->_cart_contents['total_items']);
unset($this->_cart_contents['cart_total']);
// Lets add up the individual prices and set the cart sub-total
$total = 0;
foreach ($this->_cart_contents as $key => $val)
{
// We make sure the array contains the proper indexes
if ( ! is_array($val) OR ! isset($val['price']) OR ! isset($val['qty']))
{
continue;
}
$total += ($val['price'] * $val['qty']);
// Set the subtotal
$this->_cart_contents[$key]['subtotal'] = ($this->_cart_contents[$key]['price'] * $this->_cart_contents[$key]['qty']);
}
// Set the cart total and total items.
$this->_cart_contents['total_items'] = count($this->_cart_contents);
$this->_cart_contents['cart_total'] = $total;
// Is our cart empty? If so we delete it from the session
if (count($this->_cart_contents) <= 2)
{
unset($_SESSION['cart_contents']);
// Nothing more to do... coffee time!
return FALSE;
}
// If we made it this far it means that our cart has data.
// Let's pass it to the Session class so it can be stored
$_SESSION['cart_contents'] = $this->_cart_contents;
// Woot!
return TRUE;
}
function destroy()
{
unset($this->_cart_contents);
$this->_cart_contents['cart_total'] = 0;
$this->_cart_contents['total_items'] = 0;
if(isset($_SESSION['cart_contents']))
{
unset($_SESSION['cart_contents']);
}
if(isset($_SESSION['checkout_data']))
{
unset($_SESSION['checkout_data']);
}
}
}

I just stumbled upon this tonight. The rest of the cart is fully functional. I'm wondering if anyone else has this problem, or is it just me?
