CodeIgnitor Add to Cart does not insert data in Cart array where name has a special character

I am trying to integrate add to cart in CodeIgnitor. Now the problem is that whenever I try to add a data to the cart it only inserts data whose name in the database field does not have a special character and ignores data whose name in the database field has a special character. For example, if the product name coming from database is Jeans & Top it will ignore it whereas it will accept if it is Jeans Top instead. I tried using & instead of & in the database but same problem. Do I need to escape it somewhere in the controller? If yes, how? I am new to CI. Please help me.

Controller:

public function add() {
$id = $this->input->post('id');
$product = $this->products_model->get($id);

$data = array(
'id' => $id,
'name' => $product->pro_name,
'qty' => 1,
'price' => $product->pro_price,
);
// echo "<pre>";
// print_r($data);

if($this->cart->insert($data) == TRUE) {
redirect('cart/show');
} else {
die('ERROR ADDING CART');
}
}


Model:

public function get($id) {
$results = $this->db->get_where('products', array('pro_id' => $id));
return $results->row();
}
