Codeigniter view shows 0 record - php

Question

i've insert 5 rows into ms_kategori_material table, and made some model here
function read()
{
$query = $this->db->get('ms_kategori_material');
if($query->num_rows()>0)
{
foreach ($query->result_array() as $value) {
echo $value['Kode_Kategori_Material_Jasa'];
echo $value['Nama_Material_Jasa'];
}
return $value;
}
else
{
return null;
}
}
and controllers
function index()
{
$data['kirim'] = $this->m_kategorimaterial->read();
echo $data; //returns KKMJ001batuKKMJ002batuKKMJ003batuKKMJ004batuKKMJ005batuArray
$this->load->view('v/vkategorimaterial',$data);
}
and the views
<?php
if ( !empty($kirim) ) {
$no = 1;
foreach ($kirim as $row) { ?>
<tr id="row">
<td id="no"><?php echo $no;?></td>
<td id="judul"><?php echo $row->Kode_Kategori_Material_Jasa;?></td>
<td id="kategori"><?php echo $row->Nama_Material_Jasa;?></td>
</tr> ?>
<?php
$no++;
}
} else { ?>
<tr id="row">
<td colspan="6" align="center">Data tidak ditemukan</td>
//the screen shows 'data tidak ditemukan' </tr>
<?php
}
?>
this is so confusing, since i can see the data in the controller, then pass them into the views, views said no data received

Answer 1

In your model
if($query->num_rows()>0)
{
foreach ($query->result_array() as $value) {
echo $value['Kode_Kategori_Material_Jasa'];
echo $value['Nama_Material_Jasa'];
}
return $value;
}
it's wrong, it should be
if($query->num_rows()>0)
{
return $query->result();
}
and in your controller you should have
function index()
{
$this->load->model('m_kategorimaterial'); // load it if it's not autoloaded
$data['kirim'] = $this->m_kategorimaterial->read();
$this->load->view('v/vkategorimaterial',$data);
}

Answer 2

Just reread your code. You're returning $value but never populating it. See below.
{
$query = $this->db->get('ms_kategori_material');
if($query->num_rows()>0)
{
$value = $query->result(); // or result_array() but you're using it as an object in the view not an array.
return $value;
}
else
{
return null;
}
}

Answer 3

You are actually not returning the results in your model,
replace
foreach ($query->result_array() as $value)
{
echo $value['Kode_Kategori_Material_Jasa'];
echo $value['Nama_Material_Jasa'];
}
with
if($query->num_rows()>0)
{
return $query->result();
}
