Codeigniter model not loading - codeigniter

Question

I'm a newbe in codeigniter.
something is going wrong with I think the model.
this is the controler:
<?php
class Fuel extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('html');
$this->load->library('table');
}
public function image() {
$data['title'] = 'test';
$data['main_content'] = 'imagetest';
$this->load->view("template", $data);
}
public function overview() {
$this->load->model('Get_DB');
$this->Get_DB->overview() ;
$data['title'] = 'overview';
$data['main_content'] = 'overview';
$this->load->view("template", $data);
}
when I load the image function, it works just fine, but the function overview is the problem.
this is my model:
<?php
class Get_DB extends CI_Model
{
function __construct()
{
// Call the Model constructor
parent::__construct();
}
public function overzicht() {
$query = $this->db->query("SELECT * FROM invoer "
. "ORDER BY datum DESC");
$gen_query = $this->table->generate($query);
return $gen_query;
}
}
and this is my view:
<?php
echo $gen_query;
and if you want to know: my template is this:
<?php
$this->load->view('templates/header');
$this->load->view($main_content);
$this->load->view('templates/footer');
now when I open my view I get this message:
A PHP Error was encountered
Severity: Notice Message: Undefined variable: gen_query Filename:
views/overzicht.php Line Number: 3
in the model you see that I have made a var $gen_query
so why is that undifined?

Answer 1

Try:
public function overview() {
$this->load->model('Get_DB');
$data = array();
$data['gen_query'] = $this->Get_DB->overzicht() ; #corrected model function and save the result in `gen_query`
$data['title'] = 'overview';
$data['main_content'] = 'overview';
$this->load->view("template", $data);
}

Answer 2

In Controler:
public function overview() {
$this->load->model('Get_DB');
$result = $this->Get_DB->overview() ;
$data['title'] = 'overview';
$data['main_content'] = 'overview';
$data['re'] = $result;
$this->load->view("template", $data);
}
And In view page you can retrive the result
like
foreach($re->result() as $row)
{
//You can get each row data here $row->your_field_names
}
