Menu
I'm currently editing a working project with some experience on PHP.
I know a bit about the basics but I know only a little about MVC and Code-Igniter so ofcourse I will be facing some problems.
My first problem is that i'm trying to fill a drop down list from a controller.
The view is called "overview_screen.php" and the controller is called "overview.php".
In the controller I have a function:
private function getYears()
{
return array('Test1', 'Test2', 'Test3', 'Test4');
}
which I set to $years in the index:
function index()
{
$years = $this->getYears();
$menu = $this->getMenu();
}
when I do a var_dump on the $menu it shows the menu as it should be shown but when I do the var_dump on $years it says:
PHP Error was encountered
Severity: Notice
Message: Undefined variable: years
Filename: views/overview_screen.php
Line Number: 92
Anyone know why this is happening / not working ?
[edit]
Added information:
<?php
print_r(CI_session::userdata('docent_id'));
if (!$this->session->userdata('docent_id')) {
header ('Location: /bpv-registratie/welcome.html');
}
?>
<html>
<head>
<title>Registratie Systeem</title>
</head>
<body>
<div id="topmenu">
<a href="/registratie/" class="button">Start</a>
<a href="/registratie/welcome/logout.html" class="button">Log uit</a>
</div>
<div id="topmenuright">
<?php var_dump($years); ?>
<select>
<?php foreach ($years as $row):?>
<option><?=$row?></option>
<?php endforeach;?>
</select>
</div>
<div id="menu">
{menu}
</div>
<div id="content">
{content}
</div>
</body>
</html>

You need to send variables to view file as below
function index()
{
$data['years'] = $this->getYears();
$data['menu'] = $this->getMenu();
$this->load->view('views/overview_screen.php',$data);
}
now you can use $year, $menu as variables in view file

Given the output, your view is likely to be passing through the parser library of CI.
Code should be like this:
function index()
{
$this->load->library('parser');
$data['years'] = $this->getYears();
$data['menu'] = $this->getMenu();
$this->parser->parse('overview_screen',$data);
}
I say this because I see the use of brackets inside the view file, which is how CI uses its own parsing engine (thus {menu} is treated like <?php echo $menu; ?>, which, in turn, refers to the index 'menu' you set in $data array)
You call it a view regularly; it's like @praneeth code, but without using the php extension! so:
$this->load->view('overview_screen',$data)
