i use this tutorial:http://www.derekallard.com/blog/post/building-an-rss-feed-in-code-igniter/
Please see my full code in following:
CI_Controller:

{
$data['encoding'] = 'utf-8';
$data['feed_name'] = 'neginph.com';
$data['feed_url'] = 'http://www.neginph.com';
$data['page_description'] = 'Mono-calcium phosphate and calcium phosphate producer in the Persian month Dey';
$data['page_language'] = 'en-en';
$data['creator_email'] = 'Negin phosphate North';
$data['posts'] = $this->db->order_by("id", "asc")->get_where('rss_feed', array('id' => 1));;

}
View:
<?php
echo '<?xml version="1.0" encoding="utf-8"?>' . "\n";
?>
<rss version="2.0"

<dc:rights>Copyright <?php echo gmdate("Y", time()); ?></dc:rights>
<admin:generatorAgent rdf:resource="http://www.codeigniter.com/" />
<?php foreach($posts->result() as $entry): ?>
<item>
<title><?php echo xml_convert($entry->post_title); ?></title>
<link><?php echo site_url('blog/post/' . $entry->url_title) ?></link>
<guid><?php echo site_url('blog/post/' . $entry->url_title) ?></guid>
<description><![CDATA[
<?= str_replace('/img/post_resources/', base_url() . 'img/post_resources/', $entry->post_body); ?>
]]></description>
<pubDate><?php echo date ('r', $entry->post_date);?></pubDate>
</item>
<?php endforeach; ?>
</channel></rss>
This is my output in url, why This is shown output code as this? : http://www.neginph.com/site/rss_feed

Answer 1

Respect the MVC, use "$this->db->order_by("id", "asc")->get_where ..." in a CI_Model, example:
your CI_Controller:
function rss_feed()
{
$data['encoding'] = 'utf-8'; // the encoding
$data['feed_name'] = 'MyWebsite.com'; // your website
$data['feed_url'] = 'http://www.MyWebsite.com/feed'; // the url to your feed
$data['page_description'] = 'What my site is about comes here'; // some description
$data['page_language'] = 'en-en'; // the language
$data['creator_email'] = 'mail#me.com'; // your email
$data['posts'] = $this->feed_model->getRecentPosts();
header("Content-Type: application/rss+xml"); // important!
$this->load->view('rss', $data);
}
in you CI_Model:
class Feed_Model extends CI_Model {
// get all postings
function getRecentPosts()
{
$this->db->order_by('id', 'asc');
$this->db->limit(10);
return $this->db->get('posts');
}
}
And you feed:
<?php
echo '<?xml version="1.0" encoding="utf-8"?>' . "\n";
?>
<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/">
<channel>
<title><?php echo $feed_name; ?> </title>
<link><?php echo $feed_url; ?> </link>
<description><?php echo $page_description; ?></description>
<dc:language><?php echo $page_language; ?></dc:language>
<dc:creator><?php echo $creator_email; ?></dc:creator>
<dc:rights>Copyright <?php echo gmdate("Y", time()); ?></dc:rights>
<admin:generatorAgent rdf:resource="http://www.codeigniter.com/" />
<?php foreach($posts->result() as $entry): ?>
<item>
<title><?php echo xml_convert($entry->title); ?></title>
<link><?php echo site_url('blog/post/' . $entry->id) ?></link>
<guid><?php echo site_url('blog/post/' . $entry->id) ?></guid>
<description><![CDATA[<?php echo character_limiter($entry->text, 200); ?>]]></description>
<pubDate><?php echo date ('r', $entry->date);?></pubDate>
</item>
<?php endforeach; ?>
</admin:generatoragent>
</channel>
</rss>

Answer 2

$entry->post_body isn't defined
Just a small thing as well, but you have two semicolons: $data['posts'] = $this->db->order_by("id", "asc")->get_where('rss_feed', array('id' => 1));; and that is bugging me. Valid yes, but I don't like it!
