Codeigniter: Passing data from controller to view
I want to pass $data from the controller named poll to the results_view however I am getting an undefined variable error.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Poll extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->database();
$this->load->helper('form');
}
public function index()
{
$this->load->view('poll_view',$data);
}
public function vote()
{
echo "Voting Successfull";
$this->db->insert('votes',$_POST);
}
public function results()
{
echo "These are the results";
//$query = $this->db->get('votes');
$data = "hello";
$this->load->view('results_view', $data);
}
}
Results_view.php
<html>
<?php echo $data; ?>
</html>
Answer
$data should be an array or an object: http://codeigniter.com/user_guide/general/views.html
$data = array(
'title' => 'My Title',
'heading' => 'My Heading',
'message' => 'My Message'
);
$this->load->view('results_view', $data);
results_view.php
<html>
<?php
//Access them like so
echo $title.$heading.$message; ?>
</html>
