Hi,
I extended my Cart library (MY_Cart) and is receiving below errors when updating the cart:
Undefined index: price
Undefined index: ini_price
Undefined index: books
Undefined index: toys
Below is my code (line that caused this issue made bold):
function update($items = array())
{
// Was any cart data passed?
if ( ! is_array($items) OR count($items) == 0)
{
return FALSE;
}
// You can either update a single product using a one-dimensional array,
// or multiple products using a multi-dimensional one. The way we
// determine the array type is by looking for a required array key named "id".
// If it's not found we assume it's a multi-dimensional array
$save_cart = FALSE;
if (isset($items['rowid']) AND isset($items['qty']) OR isset($items['books']) OR isset($items['toys']))
{
if ($this->_update($items) == TRUE)
{
$save_cart = TRUE;
}
}
else
{
foreach ($items as $val)
{
if (is_array($val) AND isset($val['rowid']) AND isset($val['qty']))
{
if ($this->_update($val) == TRUE)
{
$save_cart = TRUE;
}
}
}
}
// Save the cart data if the insert was successful
if ($save_cart == TRUE)
{
$this->_save_cart();
return TRUE;
}
return FALSE;
}
// --------------------------------------------------------------------
/**

function _update($items = array())
{
// Without these array indexes there is nothing we can do
if ( ! isset($items['qty']) OR ! isset($items['rowid']) OR ! isset($this->_cart_contents[$items['rowid']]))
{
return FALSE;
}
// Prep the quantity
$items['qty'] = preg_replace('/([^0-9])/i', '', $items['qty']);
$items['price'] = preg_replace('/([^0-9\.])/i', '', $items['price']);
$items['ini_price'] = preg_replace('/([^0-9\.])/i', '', $items['ini_price']);
$items['books'] = preg_replace('/([^0-9\.])/i', '', $items['books']);
$items['toys'] = preg_replace('/([^0-9\.])/i', '', $items['toys']);
// Is the quantity a number?
if ( ! is_numeric($items['qty']))
{
return FALSE;
}
// Is the new quantity different than what is already saved in the cart?
// If it's the same there's nothing to do
if ($this->_cart_contents[$items['rowid']]['qty'] == $items['qty'] AND $this->_cart_contents[$items['rowid']]['price'] == $items['price'] AND $this->_cart_contents[$items['rowid']]['books'] == $items['books'] AND $this->_cart_contents[$items['rowid']]['toys'] == $items['toys'])
{
return FALSE;
}
// Is the quantity zero? If so we will remove the item from the cart.
// If the quantity is greater than zero we are updating
if ($items['qty'] == 0)
{
unset($this->_cart_contents[$items['rowid']]);
}
elseif ($items['qty'] != 0 AND $items['price'] != 0)
{
$this->_cart_contents[$items['rowid']]['qty'] = $items['qty'];
$this->_cart_contents[$items['rowid']]['price'] = $items['price'];
$this->_cart_contents[$items['rowid']]['ini_price'] = $items['ini_price'];
$this->_cart_contents[$items['rowid']]['books'] = $items['books'];
$this->_cart_contents[$items['rowid']]['toys'] = $items['toys'];
}
else
{
$this->_cart_contents[$items['rowid']]['qty'] = $items['qty'];
}
return TRUE;
}
How can I fix it?
Many thanks.
