RSS Feed

Introduction

Generating RSS/Atom-feeds is just a matter of rendering a [api:DataObject] and the Page Comment Interface. Handled through the [api:RSSFeed] class.

RSSFeed doesn't limit you to generating "article-based" feeds, it is just as easy to create a feed of your current staff-members. The only logical limitation here is that every item in the RSS-feed should be accessible through a URL on your website, so its advisable to just create feeds from subclasses of [api:SiteTree].

Usage

Showing latest Blog posts

The first part will add an appropriate link tag for autodetecting RSS feeds
The second part sets up /this-page/rss to return the RSS feed. This one returns the children of the current page.

:::php function init() { RSSFeed::linkToFeed($this->Link() . "rss", "RSS feed of this blog"); parent::init(); }
```
 function rss() {
 	$rss = new RSSFeed($this->Children(), $this->Link(), "My feed", "This is an example feed.", "Title", "Content", "Author");
 	$rss->outputToBrowser();
 }
```

Example of showing the 10 most recently updated pages

You can use RSSFeed to easily create a feed showing your latest Page updates. Just change mysite/code/Page.php to something like this:

:::php
<?php
class Page extends SiteTree {
	static $db = array(
	);
	static $has_one = array(
   );
}

class Page_Controller extends ContentController {

	function init() {
		RSSFeed::linkToFeed($this->Link() . "rss", "10 Most Recently Updated Pages");
		parent::init();
	}
	
	function rss() {
		$rss = new RSSFeed($this->LatestUpdates(), $this->Link(), "10 Most Recently Updated Pages", "Shows a list of the 10 most recently updated pages.", "Title", "Content", "Author");
		$rss->outputToBrowser();
	}

	function LatestUpdates() {
		// 10 is the number of pages
		return DataObject::get("Page", "", "LastEdited DESC", "", 10);
	} 
}

?>

Viewing Comment RSS Feeds

You can view RSS feeds for comments for a certain page or for all comments on your site by visiting http://www.yoursite.com/PageComment/rss . That produces a RSS Feed of the most recent comments to all of your site. You can also do http://www.yoursite.com/PageComment/rss?pageid=46 where pageid is the id of the page you want to follow

External Sources

RSSFeed only creates feeds from your own data. We've included the SimplePie RSS-parser for accessing feeds from external sources.
