SimplePie multiple feed demonstration code doesn't work. What should I use instead?

I am trying to figure out why the code posted on the SimplePie website for displaying multiple feeds doesn't work. Specifically, this code example:

http://simplepie.org/wiki/tutorial/sort_multiple_feeds_by_time_and_date

Here is specifically what I am using:

<?php
// Include the SimplePie library
// For 1.0-1.2:
#require_once('simplepie.inc');
require_once($_SERVER['DOCUMENT_ROOT']."/path/to/simplepie/autoloader.php");
// For 1.3+:

// Create a new SimplePie object
$feed = new SimplePie();

// Instead of only passing in one feed url, we'll pass in an array of three
$feed->set_feed_url(array(

));

// Initialize the feed object
$feed->init();

// This will work if all of the feeds accept the same settings.
$feed->handle_content_type();

        <?php foreach ($feed->get_items() as $item): ?>

        <div class="chunk">

            <?php /* Here, we'll use the $item->get_feed() method to gain access to the parent feed-level data for the specified item. */ ?>
            <h4 class="title" style="background-image:url(<?php $feed = $item->get_feed(); echo $feed->get_favicon(); ?>);"><a href="<?php echo $item->get_permalink(); ?>"><?php echo $item->get_title(); ?></a></h4>

        </div>

        <?php endforeach; ?>

    </div>
</body>

And this is the HTML output I get:

    <div id="site">

        <div class="chunk">

<b>Fatal error</b>:  Call to a member function get_base() on a non-object in <b>/home/user/domain/folder/subfolder/simplepie/library/SimplePie/Item.php</b> on line <b>167</b><br />

I've tried tinkering around with the code (for instance, I can do without favicons), but I always get fatal error messages saying "Call to a member function [fill in the blank] on a non-object in [SimplePie file]".

Is there more up-to-date code that I should be using as a template for constructing pages that process multiple feeds? What's breaking that's preventing SimplePie from working?

Solution

  • I'm not sure what version of SimplePie you're using but apparently

    Favicon handling has been removed, please use your own handling in /home/user/domain/library/SimplePie.php on line 2946

    Assuming you don't want to debug SimplePie itself, you should not call this:

    $feed->get_favicon()

    For starters. I don't know why favicon support was removed, because I use it, but then again I might have written a work around or I'm using an older (inferior) version of SimplePie. Yank out the favicon stuff and try again.
