Load table from database to dropdown CodeIgniter - codeigniter

Question

I have trouble with loading the table to the form_dropdown. I have tried any solution from the same trouble with me but its not working.
Here's the controller code:
<?php
class Registrasi extends Superuser_Controller
{
public $data = array(
'halaman' => 'registrasi',
'main_view' => 'program/administrasi/registrasi_list',
'title' => 'Data Registrasi',
);
public function __construct()
{
parent::__construct();
$this->load->model('program/administrasi/Registrasi_model', 'registrasi_model');
}
public function index()
{
$registrasi = $this->registrasi_model->get_all_registrasi_data();
$this->data['registrasiData'] = $registrasi;
$this->load->view($this->layout, $this->data);
}
public function tambah()
{
$this->data['namaNegara'] = $this->registrasi_model->get_nama_negara();
$this->data['main_view'] = 'program/administrasi/registrasi_form';
$this->data['form_action'] = site_url('program/administrasi/registrasi/tambah');
// Data untuk form.
if (! $_POST) {
$registrasi = (object) $this->registrasi_model->default_value;
} else {
$registrasi = $this->input->post(null, true);
}
// Validasi.
if (! $this->registrasi_model->validate('form_rules')) {
$this->data['values'] = (object) $registrasi;
$this->load->view($this->layout, $this->data);
return;
}
}
}
Here's the model code:
<?php
class Registrasi_model extends MY_Model
{
protected $_tabel = 'tb_registrasi';
protected $form_rules = array(
array(
'field' => 'Negara_Tujuan',
'label' => 'Negara Tujuan',
'rules' => 'trim|xss_clean|required|max_length[50]'
)
);
public $default_value = array(
'Negara_Tujuan' => ''
);
public function get_nama_negara()
{
$query = $this->db->query('SELECT Nama_Negara FROM tb_negara_tujuan');
return $query->result();
}
}
Here's the view code:
<div class="container">
<h2>Form Registrasi</h2>
<hr>
<?php echo form_open($form_action, array('id'=>'myform', 'class'=>'myform', 'role'=>'form')) ?>
<div class="container">
<div class="row">
<div class="form-group has-feedback <?php set_validation_style('Negara_Tujuan')?>">
<?php echo form_label('Negara Tujuan', 'negara_tujuan', array('class' => 'control-label')) ?>
<?php
foreach($namaNegara as $row)
{
echo form_dropdown('NegaraTujuan', $row->Nama_Negara);
}
?>
<?php set_validation_icon('Negara_Tujuan') ?>
<?php echo form_error('Negara_Tujuan', '<span class="help-block">', '</span>');?>
</div>
<?php echo form_button(array('content'=>'Simpan', 'type'=>'submit', 'class'=>'btn btn-primary', 'data-confirm'=>'Anda yakin akan menyimpan data ini?')) ?>
</div>
</div>
<?php echo form_close() ?>
</div>
The trouble I'm having is: Invalid argument supplied for foreach()

Answer 1

Your controller code must be :-
public function tambah()
{
$namaNegara[''] = 'select a option';
$namaNegaras = $this->registrasi_model->get_nama_negara();
foreach($namaNegaras as $namaNegaranew)
{
$namaNegara[$namaNegaranew->id] = $namaNegaranew->Nama_Negara ;
}
$this->data['namaNegara'] = $namaNegara;
$this->data['main_view'] = 'program/administrasi/registrasi_form';
$this->data['form_action'] = site_url('program/administrasi/registrasi/tambah');
// Data untuk form.
if (! $_POST) {
$registrasi = (object) $this->registrasi_model->default_value;
} else {
$registrasi = $this->input->post(null, true);
}
// Validasi.
if (! $this->registrasi_model->validate('form_rules')) {
$this->data['values'] = (object) $registrasi;
$this->load->view($this->layout, $this->data);
return;
}
}
And in view in place of
<?php
foreach($namaNegara as $row)
{
echo form_dropdown('NegaraTujuan', $row->Nama_Negara);
}
?>
Simply use
<?php echo form_dropdown('NegaraTujuan', $namaNegara , set_value('NegaraTujuan')); ?>

I think i have the answer for my problem:
Controller code (still same, no change whatsoever)
Model code: change the function into
public function get_nama_negara()
{
$query = $this->db->query('SELECT Nama_Negara FROM tb_negara_tujuan');
$dropdowns = $query->result();
foreach ($dropdowns as $dropdown)
{
$dropdownlist[$dropdown->Nama_Negara] = $dropdown->Nama_Negara;
}
$finaldropdown = $dropdownlist;
return $finaldropdown;
}
View code:
<div class="container">
<h2>Form Registrasi</h2>
<hr>
<?php echo form_open($form_action, array('id'=>'myform', 'class'=>'myform', 'role'=>'form')) ?>
<div class="container">
<div class="row">
<div class="form-group has-feedback <?php set_validation_style('Negara_Tujuan')?>">
<?php echo form_label('Negara Tujuan', 'negara_tujuan', array('class' => 'control-label')) ?>
<?php echo form_dropdown('NegaraTujuan', $namaNegara, set_value('NegaraTujuan'), 'class="dropdown"'); ?>
<?php set_validation_icon('Negara_Tujuan') ?>
<?php echo form_error('Negara_Tujuan', '<span class="help-block">', '</span>');?>
</div>
<?php echo form_button(array('content'=>'Simpan', 'type'=>'submit', 'class'=>'btn btn-primary', 'data-confirm'=>'Anda yakin akan menyimpan data ini?')) ?>
</div>
</div>
<?php echo form_close() ?>
</div>
