I am trying to work through the CodeIgniter tutorial and my news pages won’t output data from the foreach loop. I get the following messages:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: news
Filename: pages/index.php
Line Number: 1
and
A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: pages/index.php
Line Number: 1
This is my model class:
<?php
class News_model extends CI_Model {
public function __construct()
{
$this->load->database();
}
public function get_news($slug = FALSE)
{
if ($slug === FALSE)
{
$query = $this->db->get('news');
return $query->result_array();
}
$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}
public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
}And my controller:
class News extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('news_model');
}
public function index()
{
$data['news'] = $this->news_model->get_news();
}
public function view($slug)
{
$data['news_item'] = $this->news_model->get_news($slug);
if (empty($data['news_item']))
{
show_404();
}
$data['title'] = $data['news_item']['title'];
$this->load->view('templates/header', $data);
$this->load->view('news/view', $data);
$this->load->view('templates/footer');
}
}And the first view:
<h2><?php echo $news_item['title'] ?></h2>
<p> <div id="main"><br />
<?php echo $news_item['text'] ?><br />
</div><br />
<a href="http://news/<?php"> ?>"]View article</a></p>
<p><?php endforeach ?>and the second:
<?php
echo '<h2>'.$news_item['title'].'</h2><p>';<br />
echo $news_item['text'];I hope it isn’t something too stupid!
Thanks.
