Menghitung jumlah di Codeigniter

Pada Controller index tambahkan var  $saldo  isinya diperoleh dari
model saldo fungsi ambil nilai saldo..lalu tambahkan $saldo ke array($data)
yg akan dikirim ke view index

krg lebih gini lah ...
<?php

$saldo = $this->M_saldo->getSaldo();

$data['title'] = "SIGN UP";
$data['saldo'] = $saldo;

$this->template->display('nama_view', $data);

?>

nanti pada view index olah $saldo.. sesuai kebutuhan bukan $row->saldo..
tapi $saldo.. tergantung return dari fungsi ambil nilai saldo agan..

oke gan bentar hehe

cara ngolah di viewnya contohnya gimana gan ?

ya perulangan biasa yg disesuaikan dikit..tergantung return dari fungsi ambil saldonya apa ? array atau gmn..

tinggal dikondisikan dengan data yg di foreach() dari "web" klw gk salah ya..

kalau belum bisa coba code nya copy sini..soalnya kode agan gk jelas.. jgn ditaruh di image.lsg pake simbol [] aj...

Baik gan hehe

Model :

  private $table="user";
    private $primary="id_user";

    function semua(){
        $query=$this->db->query("select * from user");
        return $query;
    }
    function saldo_customer(){
        $query=$this->db->query("select * from saldo_topup");
    }
    function getUser($table,$id){
        return $this->db->get_where($table,$id);
    }
    function get_saldo(){

        $query=$this->db->query("select username,nama_customer,tgl_topup,jumlah, s.status, ket, bank, bukti, id_topup from saldo_topup s join user u on u.id_user=s.id_user");
        return $query;

    }
    function get_saldoAkhir($id){

        $query=$this->db->query("select * from kartu where id_user = $id");
        return $query;

    }

- Controller index

 function index($offset=0,$order_column='id',$order_type='desc'){
         if($this->session->userdata("username") == null)
        {
            redirect("login/index");
        }
        else
        {
           $data['username']=$this->session->userdata("username");
        }
        if(empty($offset)) $offset=0;
        if(empty($order_column)) $order_column='id';
        if(empty($order_type)) $order_type='desc';

        //load data
        $data['web']=$this->m_customer->semua()->result();
        $data['title']="Sign Up";



        $config['base_url']=site_url('customer/index/');
        $config['total_rows']=$this->m_customer->jumlah();

        if($this->uri->segment(3)=="delete_success")
            $data['message']="<div class='alert alert-success'>Deleted Successfully!</div>";
        else if($this->uri->segment(3)=="add_success")
            $data['message']="<div class='alert alert-success'>Inserted Successfully</div>";
