Codeigniter cart has predefined format:
https://ellislab.com/codeigniter/user-guide/libraries/cart.html
$data = array(
'id' => 'sku_123ABC',
'qty' => 1,
'price' => 39.95,
'name' => 'T-Shirt',
'options' => array('Size' => 'L', 'Color' => 'Red')
);
$this->cart->insert($data);
So you code will be,
function add()
{
$data = array(
'id'=>someID,
'name'=>SomeName,
'qty' => $this->input->post('qty'),
'price' => $this->input->post('price'),
'options' =>array('id_books'=> $this->input->post('id_books'),'id_category'=> $this->input->post('id_category'),'images' => $this->input->post('images'),'title' => $this->input->post('title'));
$this->cart->insert($data);
/*print_r($data);*/
/*echo "<meta http-equiv='refresh' content='0; url=".base_url()."cart/'>";*/
redirect('cart','refresh');
}
