Function won't pass variable to view - php

Question

Right now $renderData['username'] won't pass through to the view.
class HomeController extends MY_Controller {
public function index($renderData=""){
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');
$renderData['username'] = $session_data['username'];
//$this->load->view('pages/home_view', $renderData);
$this->_render('pages/home',$renderData);
}
else
{
//If no session, redirect to login page
redirect('LoginController', 'refresh');
}
}
}
The error I get is...
Which alludes to this code...
<h1>Home</h1>
<h2>Welcome <?php echo $username; ?>!</h2>
Logout
Here is my My_Controller where the _render function is located...
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller{
//Page info
protected $data = Array();
protected $pageName = FALSE;
protected $template = "main";
protected $hasNav = TRUE;
//Page contents
protected $javascript = array();
protected $css = array();
protected $fonts = array();
//Page Meta
protected $title = FALSE;
protected $description = FALSE;
protected $keywords = FALSE;
protected $author = FALSE;
function __construct()
{
parent::__construct();
$this->data["uri_segment_1"] = $this->uri->segment(1);
$this->data["uri_segment_2"] = $this->uri->segment(2);
$this->title = $this->config->item('site_title');
$this->description = $this->config->item('site_description');
$this->keywords = $this->config->item('site_keywords');
$this->author = $this->config->item('site_author');
$this->pageName = strToLower(get_class($this));
}
protected function _render($view,$renderData="FULLPAGE") {
switch ($renderData) {
case "AJAX" :
$this->load->view($view,$this->data);
break;
case "JSON" :
echo json_encode($this->data);
break;
case "FULLPAGE" :
default :
//static
$toTpl["javascript"] = $this->javascript;
$toTpl["css"] = $this->css;
$toTpl["fonts"] = $this->fonts;
//meta
$toTpl["title"] = $this->title;
$toTpl["description"] = $this->description;
$toTpl["keywords"] = $this->keywords;
$toTpl["author"] = $this->author;
//data
$toBody["content_body"] = $this->load->view($view,array_merge($this->data,$toTpl),true);
//nav menu
if($this->hasNav){
$this->load->helper("nav");
$toMenu["pageName"] = $this->pageName;
$toHeader["nav"] = $this->load->view("template/nav",$toMenu,true);
}
$toHeader["basejs"] = $this->load->view("template/basejs",$this->data,true);
$toBody["header"] = $this->load->view("template/header",$toHeader,true);
$toBody["footer"] = $this->load->view("template/footer",'',true);
$toTpl["body"] = $this->load->view("template/".$this->template,$toBody,true);
//render view
$this->load->view("template/skeleton",$toTpl);
break;
}
}
}
Here is an additional function that may be helpful...
class VerifyLogin extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('user','',TRUE);
}
function index()
{
//This method will have the credentials validation
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');
if($this->form_validation->run() == FALSE)
{
//Field validation failed. User redirected to login page
$this->load->view('pages/login_view');
}
else
{
//Go to private area
// redirect('home', 'refresh');
redirect('HomeController', 'refresh');
}
}
function check_database($password)
{
//Field validation succeeded. Validate against database
$username = $this->input->post('username');
//query the database
$result = $this->user->login($username, $password);
if($result)
{
$sess_array = array();
foreach($result as $row)
{
$sess_array = array(
'id' => $row->id,
'username' => $row->username
);
$this->session->set_userdata('logged_in', $sess_array);
}
return TRUE;
}
else
{
$this->form_validation->set_message('check_database', 'Invalid username or password');
return false;
}
}
}
?>
What am I doing wrong that is preventing the username to be passed to the view?
PS - let me know any additional documentation I can provide.

Answer 1

something like this
protected function _render($view,data, $renderData="FULLPAGE") {
$this->data = $data;
switch ($renderData) {
case "AJAX" :
$this->load->view($view,$this->data);
break;
case "JSON"
