Hi all,

Currently working with the shopping cart class and ive got working the insert in cart and to show the cart items but when i do update of qty nothing happens...

Here's the code:

Code:

function update_cart()
{
  $update = array(
          'rowid' => $this->input->post('rowid'),
          'qty'   => $this->input->post('qty')
  );

  $this->cart->update($update);
  $this->session->set_flashdata('message','Your shopping cart has been updated!');
    redirect('home/cart','refresh');
}

Just been referencing to the manual, so nothing used in terms of anyone elses classes or libs.
Help greatly appreciated.
