Answer 1

You are storing the result from database to array tests here
$data['tests'] = $this->customer_model->tampil_data_customer();
and trying to call it in view with an undefined array $results.
Try with this.
if(!empty($tests->result())){
foreach($tests->result() as $isi)
{
echo "<tr>";
echo "<td>".$isi->nama."</td>";
echo "<td>".$isi->company."</td>";
echo "<td>".$isi->alamat."</td>";
echo "<td>".$isi->telepon."</td>";
echo "<td>".$isi->hp."</td>";
echo "</tr>";
}
}
In model can you make it simple like this,
public function tampil_data_customer()
{
$query=$this->db->query('select * from customer');
$results = $query->result();
return $results;
}

when you pass in arguments using $this->load->view() function,you are using the view() function with the instance of Loader load,it's in /system/core/Loader.php. As the block comments say
An associative array of data to be extracted for use in the view.
if you pass in an object,you can get the public properties by simply using the property name,you can't get the protected and private property.
if you pass in an Multi-dimensional Array,you can get the value by using key/keys in the Multi-dimensional Array.
By the way,you must pass in an array or object other a variable.
sample below
model.php(application\models\test)
class model extends CI_Model {
public $ss=1;
protected $bb=1;
private $vv=3;
}
controller.php(application\controllers)
class Hello extends CI_Controller
public function __construct() {
parent::__construct ();
}
public function index() {
$this->load->model('test/model');
$model=new model();
$this->load->view ( 'test/view', $model );
}
view.php(application\views\test)
echo $ss;
then you get the value of object.
