RSS Feed using Codeigniter - php

Question

I create an RSS Feed using Codeigniter following tutorials from here
but my problem is the feed content is not displaying on the page but available if you browse the html source.
here is my controller code:
public function __construct()
{
parent::__construct();
$this->load->model('articles_model');
$this->load->helper('xml');
$this->load->helper('text');
}
public function index()
{
$data['feed_name'] = 'MyDebut.ph';
$data['encoding'] = 'utf-8';
$data['feed_url'] = 'http://www.mydebut.com/feeds';
$data['page_description'] = 'Everything for turning 18.';
$data['page_language'] = 'en-en';
$data['creator_email'] = 'mydebutph#gmail.com';
$data['posts'] = $this->articles_model->getArticlesPaginated(0,30);
header("Content-type: text/xml; charset=utf-8");
$this->load->view('rss', $data);
}
my view code:
<?php echo '<?xml version="1.0" encoding="' . $encoding . '"?>' . "\n"; ?>
<rss version="2.0">
<channel>
<title><?php echo $feed_name; ?></title>
<description><?php echo $page_description; ?></description>
<link><?php echo $feed_url; ?></link>
<?php foreach ($posts as $post): ?>
<item>
<title><?php echo xml_convert($post['art_title']); ?></title>
<link><?php echo base_url().'blogs/'.$post['sec_slug'].'/'.$post['cat_slug'].'/'.$post['art_slug'];?>
<description><?php echo character_limiter($post['art_sub'], 300); ?></description>
</item>
<?php endforeach; ?>
</channel>
</rss>

Answer 1

View Buffer
Make sure you set the buffer(view as string) by passing true as the third parameter
$view = $this->load->view('rss', array('data'=>$data), true);
Ouput Class
You can use the output class to send the buffer(not the view itself) directly to the browser
$this->output->set_content_type('application/rss+xml')->set_output(file_get_contents($view));
Use Proper Meta attributes
<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:admin="http://webns.net/mvcb/" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:content="http://purl.org/rss/1.0/modules/content/">
Link to Xml Document
Add this to the head of the document. (only on blog page)
<link rel="alternate" type="application/rss=xml" title="Blog Feed" href="<?php echo site_url('rss'); ?> "/>

I don't know what is in your Model code but as far I can see in your controller you aren't getting the result array from the model. Check the 22 line of the rss view...
<?php foreach($posts->result() as $post): ?>
Also check this documentation, maybe could help you
