  Previous article Next article  

Create your own XML or RSS-feed reader with plain Smarty, there are no external modules or plug-ins needed!

  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.

{$xml = simplexml_load_file('https://www.cmscanbesimple.org/feeds/blog.rss')}

{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:

$config['permissive_smarty'] = 1;

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
