codeigniter Update cart item


Example

Rowid : The row ID is a unique identifier that is generated by the cart code when an item is added to the cart. The reason a unique ID is created is so that identical products with different options can be managed by the cart.

Every item in cart has a rowid element and by rowid you can update cart item.

$updateItem = array(
    'rowid' => 'b99ccdf16028f015540f341130b6d8ec',
    'qty'   => 3
);

and then below code

$this->cart->update($data);
