How to convert php script to codeigniter MVC? - php

Question

I have PHP script and work:
<?php
$con=mysqli_connect("localhost","root","","dbm");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result3 = mysqli_query($con,"select t.tgl_transaksi, p.kode_produk, tp.hp_tujuan, d.nama as nama2, sr.ket as ket2 from dbm.transaksi_psa tp
left join dbm.transaksi t
on tp.id_transaksi=t.id_transaksi
left join dbm.produk p
on tp.kode_produk = p.kode_produk
left join dbm.set_report sr on t.status=sr.jenis
left join dbm.distributor d on (tp.id_distributor=d.id_distributor and tp.com=d.com)
where date(t.tgl_transaksi)=date(now())
order by t.tgl_transaksi DESC");
echo "
<div class='table-responsive'>
<table class='table table-hover' id='t01'>
<tr>
<th>Tanggal</th>
<th>Produk</th>
<th>Tujuan</th>
<th>Suplier</th>
<th>Status</th>
</tr>";
while ($row = mysqli_fetch_array($result3))
{
echo "<tr>";
echo "<td>" . $row['tgl_transaksi'] . "</td>";
echo "<td>" . $row['kode_produk'] . "</td>";
echo "<td>" . $row['hp_tujuan'] . "</td>";
echo "<td>" . $row['nama2'] . "</td>";
echo "<td>" . $row['ket2'] . "</td>";
echo "</tr>";
}
echo "</table></div> <br><br><br>";
mysqli_close($con);
?>
And I try change to Codeigniter MVC - OOP:
Models:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Ikhtisar_model extends CI_Model{
function __construct()
{
// Call the Model constructor
parent::__construct();
}
//read the ikhtisar list from db
public function get_all()
{
$this->db->select('t.tgl_transaksi AS tgl, p.kode_produk AS kode, tp.hp_tujuan AS nohp, d.nama AS nama2, sr.ket AS ket2', FALSE)
->from('transaksi_pulsa tp')
//$this->db->where('date(t.tgl_transaksi)', 'date(now())');
->join('transaksi t','tp.id_transaksi=t.id_transaksi', 'left')
->join('produk p','tp.kode_produk = p.kode_produk', 'left')
->join('set_report sr','t.status=sr.jenis', 'left')
->join('distributor d','tp.id_distributor=d.id_distributor and tp.com=d.com', 'left')
->order_by("t.tgl_transaksi", "DESC");
$ikhtisar = $this->db->get();
//->result_array();
//return $ikhtisar;
}
}
Controllers:
<?php
if ( ! defined('BASEPATH')) exit('Akses di blok. Cek kembali link yang Anda tuju!');
class ikhtisar extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('url');
$this->load->database();
}
public function index()
{
//load the ikhtisar_model
$this->load->model('ikhtisar_model');
//call the model function to get the ikhtisar data
$ikhresult = $this->ikhtisar_model->get_all();
$data['ikhlist'] = $ikhresult;
//load the ikhtisar_view
$this->load->view('templates/header', $data);
$this->load->view('ikhtisar_view',$data);
$this->load->view('templates/footer', $data);
}
}
Views:
<!-- BEGIN CONTENT -->
<div class="page-content-wrapper">
<div class="page-content">
<div class="row">
<div class="col-md-12 col-sm-12">
<table class="table table-striped table-hover">
<thead>
<tr>
<th>Tanggal</th>
<th>Produk</th>
<th>Tujuan</th>
<th>Suplier</th>
<th>Status</th>
</tr>
</thead>
<tbody>
<? foreach($ikhtisar->result_array() as $ikh): ?>
<tr>
<td><?=$ikhlist['tgl']?></td>
<td><?=$ikhlist['kode']?></td>
<td><?=$ikhlist['nohp']?></td>
<td><?=$ikhlist['nama2']?></td>
<td><?=$ikhlist['ket2']?></td>
</tr>
<? endforeach; ?>
</tbody>
</table>
</div>
</div>
</div>
</div>
But, what I get, the data doesn't display at all. The header, the footer, display correctly.

Answer 1

First you have to return data from your model
class Ikhtisar_model extends CI_Model{
public function get_all()
{
.........................
$ikhtisar = $this->db->get();
return $ikhtisar;
}
}
second you have to pass data to your view from contorller. You already did it.
public function index()
{
//load the ikhtisar_model
$this->load->model('ikhtisar_model');
//call the model function to get the ikhtisar data
$ikhresult = $this->ikhtisar_model->get_all();
$data['ikhlist'] = $ikhresult;//you got it and you will get your variable as $ikhlist at your view
//load the ikhtisar_view
$this->load->view('templates/header', $data);
$this->load->view('ikhtisar_view',$data);
$this->load->view('templates/footer', $data);
}
Now display at your view.You wrote foreach loop worng.It should be like this
<? foreach($ikhlist->result_array() as $ikh): ?>
<tr>
<td><?=$ikh['tgl']?></td>
<td><?=$ikh['kode']?></td>
<td><?=$ikh['nohp']?></td>
<td><?=$ikh['nama2']?></td>
<td><?=$ikh['ket2']?></td>
</tr>
<? endforeach; ?>
better use full php tag instead of short tag.like this
<?php instead of <?
and
<?php echo instead <?=

Thanks for helping me, Mr. Shaiful Islam. All I get, this error:
