sending data from controller to model - ajax

Question

I have the following code on my site which sending data to Ajax and works normal. It is about add to cart.
public function adding()
{
$id_lap=$this->input->post('id_lap');
$num_items=$this->input->post('num_items');
$price=$this->input->post('price');
if($id_lap !='')
{
$this->session->set_userdata('num_items',$num_items);
$this->session->set_userdata('price_new',$price);
$response=array(
'status'=>1,
'num_items'=>$num_items,
'price_new'=>$price
);
} else {
$response=array(
'status'=>0
);
}
echo json_encode($response);
}
When I want to send data to model also where I want to write data into database along with IP adress which I will collect with model. When I add new row anywhere my Ajax crashed. Part of code which I want to add is:
$this->users_mod->AddSesija($id_lap,$price);
And Ajax code which I am using is :
function Addtocart(id,prices)
{
var id_lap=id;
var ajaxURL= BASE_URL +'home/adding';
var num_items = parseInt($('#num_items').html()) + 1;
var price = parseInt($('#price_b').html());
var price_new = price + prices;
/*console.log(id_lap +' '+num_items+' '+price_new);
$('#num_items').html(num_items);
$('#price_b').html(price_new); */
$.ajax({
url:ajaxURL,
type:'POST',
data:{'id_lap':id_lap,'num_items':num_items,'price':price_new},
success:function(response)
{
var parsed = JSON.parse(response);
if(parsed.status ==1)
{
$('#num_items').html(parsed.num_items);
$('#price_b').html(parsed.price_new);
}
}
}
)
}

I am agree with Vladimir Glisovic in concept. we know that for adding or inserting group of data we should bind them into an array.
Sample:
$data=array( 'ip_adress'=>$ip_adress, 'id_lap'=>$id_lap, 'cena'=>$price );
N.b: get IP address from PHP code keep in $ip_address.
Then pass the data to model with the CI syntax.
Model calling in Controller:
$this->users_mod->AddSesija($data);
Now write the inserting code in the model file as
public function AddSesija($data){
insertion code here.....
}
Hope it will help you.
Thanks!
