Usage example: You have discovered a site that provides feeds which are hidden and inaccessible by normal means. You want your bridge to directly read the feeds and provide them via RSS-Bridge

Find a template at the end of this file.

Notice: For a standard feed only collectData need to be implemented. collectData should call $this->collectExpandableDatas('your URI here'); to automatically load feed items and header data (will subsequently call parseItem for each item in the feed). You can limit the number of items to fetch by specifying an additional parameter for: $this->collectExpandableDatas('your URI here', 10) (limited to 10 items).

The parseItem method

This method receives one item from the current feed and should return one RSS-Bridge item. The default function does all the work to get the item data from the feed, whether it is RSS 1.0, RSS 2.0 or Atom 1.0.

Notice: The following code sample is just an example. Implementation depends on your requirements!

protected function parseItem(array $item)
{
    $item['content'] = str_replace('rssbridge','RSS-Bridge',$item['content']);
    return $item;
}

Feed parsing

How rss-bridge processes xml feeds:

Function	uri	title	timestamp	author	content
atom	id	title	updated	author	content
rss 0.91	link	title			description
rss 1.0	link	title	dc:date	dc:creator	description
rss 2.0	link, guid	title	pubDate, dc:date	author, dc:creator	description

Template

This is the template for a new bridge:

<?php
class MySiteBridge extends FeedExpander
{

    const MAINTAINER = 'No maintainer';
    const NAME = 'Unnamed bridge';
    const URI = '';
    const DESCRIPTION = 'No description provided';
    const PARAMETERS = [];
    const CACHE_TIMEOUT = 3600;

    public function collectData()
    {
        $this->collectExpandableDatas('your feed URI');
    }
}
