Cannot Pass More than two variable to view

Check your model, and change the function employee_spends() :

PHP Code:

function employee_spends($id)
{
    $query = $this->db->query("SELECT SUM(price) as total FROM inventory WHERE employee_id=" . $id);
    if ($query->num_rows() == 0) {
        return 0;
    }
    else {
        return $query->row()->total;
    }
}
