How to use
Page
Create a new content page and set WYSIWYG off.
Copy the following code in the content of the page. Note, this template is just an example: with the parameters below you can change it to your liking.
In the first line you can add the URL of the feed you want to display at your website.
{if !empty($xml)}
<h3>{$xml->channel->title}</h3>
<h4>{$xml->channel->description}</h4>
<p>Generator: {$xml->channel->generator}<br />
URL: {$xml->channel->link}<br />
Copyright: {$xml->channel->copyright}</p>
{$cnt = 0}
{foreach $xml->channel->item as $item}
<h4><a href="{$item->link}">{$item->title}</a></h4>
<p>{$item->pubDate|date_format:'%e %B %Y'}<br />
{$item->author}: {$item->description} <a href="{$item->guid}">Read more</a></p>
{$cnt = $cnt + 1}
{if $cnt == 2}{break}{/if}
{/foreach}
{else}
<p>No feed found...</p>
{/if}
The number "2" in the $cnt line above, is the number of feed items that will be shown at your page.

Permissive Smarty
In the latest Smarty releases due to security settings PHP functions aren't available by default... If you do want to use PHP functions, you have to enable them by adding this line to your CMSMS config.php file:
This config variable loosens some of the security configuration for Smarty templates. Particularly enabling this option allows the use of any PHP function as a Smarty plugin. You better not use this option if you are allowing content to be submitted for display on your website from untrusted sources!
If the feed reader works without this line, you better not add it!
Working example
The next example is the output of the template described above and displays the CMS Can Be Simple blog feed:

Hello!
I'm trying to get featured image to display in rssfeed - without much luck!
PHP file contains following:
public function hookDisplayFooter($params)
{
// Conf
$title = strval(Configuration::get('RSS_FEED_TITLE'));
$url = strval(Configuration::get('RSS_FEED_URL'));
$nb = (int) (Configuration::get('RSS_FEED_NBR')) ? (int) (Configuration::get('RSS_FEED_NBR')) : 5;
$cacheId = $this->getCacheId($this->name . '|' . date("YmdH"));
if (!$this->isCached($this->templateFile, $cacheId)) {
$rss_links = array();
if ($url && ($contents = Tools::file_get_contents($url))) {
try {
$xml = new SimpleXMLElement($contents);
$loop = 0;
if (!empty($xml->channel->item)) {
foreach ($xml->channel->item as $item) {
if (++$loop > $nb) {
break;
}
$rss_links[] = (array)$item;
}
}
} catch (Exception $e) {
Tools::dieOrLog($this->trans('Error: invalid RSS feed in "%module_name%" module: %message%', array('%module_name%' => $this->name, '%message%' => $e->getMessage()), 'Modules.Rssfeed.Admin'));
}
}
$this->smarty->assign(array(
'title' => ($title ? $title : $this->trans('RSS feed', array(), 'Modules.Rssfeed.Admin')),
'rss_links' => $rss_links
));
}
return $this->fetch($this->templateFile, $cacheId);
}
Smarty tpl file:
Latest Posts from our Temperature Blog
{if $rss_links}
{foreach from=$rss_links item='rss_link'}
{$rss_link.title}{$rss_link.description|truncate:150|escape:'UTF-8'}
{/foreach}
{else}
{l s='No RSS feed added'}
{/if}
What am I missing?
Thanks
Hello Vincent,
The photo's in that feed are included in the description/content field and not seperately attached. Your options are more limited by this.
Change the feed or contact the owner of that website and let him change it...
Grtz. Rolf
Hello thank's for this but i can't import the image how i can proceed if you have an idea ?
I want to import rss flux from this wordpress blog : http://blog.colvert.com
Any idea to help me please ?
Hi,
I i'm using this methode, but i have a problem with caching.
I can use your Cache remote file plugin for this but i don't seem to get it working.
Thank you, Joni!!

I updated the post with a check if the feed is present and added the enclosure tag to retrieve the item image URL from the news feed.
Bravo, Rolf. This is exactly what I am looking for on a page for a client!!!
