some doubts about the coding standard

Yeah, that way there is repetition. You can use $this->input->post in model straight but I would do it differently. In model I would have this:

Code:

function insert_db($data)
{
    if (empty($data))
    {
        return false;
    }
    
    $this->db->insert('product',$data);
    return $this->db->insert_id();
}

That way you can pass any data to your model(eg. if your schema changes) and dont have to repeat code.
