Pagination problem driving me insane

cormac · August 27, 2008

Hi,

I've been trying to solve this problem myself for hours but I've had no luck whatsoever, the problem is I don't know PHP, the page I have is hacked together from a few different scripts and seems to be 90% functional but when I click the 'next' and 'previous' links nothing happens. So I'm lost and would really appreciate some help!

There is a demo of the page at http://d366804.u40.hosting.digiweb.ie/test/index-old1.php

The code is as follows:

<?php
require_once('simplepie.inc');

// Set your own configuration options as you see fit.
$feed = new SimplePie();
$feed->set_feed_url(array(
'http://www.independent.ie/business/rss',
'http://www.irishtimes.com/feeds/rss/breaking/business.rss',
'http://www.irishexaminer.com/rss/irishexaminer_business_rss.aspx'
));

$success = $feed->init();
$feed->handle_content_type();

$total_articles = 3;

for ($x = 0; $x < $feed->get_item_quantity($total_articles); $x++)
{
	$first_items[] = $feed->get_item($x);
}// Set our paging values
$start = (isset($_GET['start']) && !empty($_GET['start'])) ? $_GET['start'] : 0; // Where do we start?
$length = (isset($_GET['length']) && !empty($_GET['length'])) ? $_GET['length'] : 3; // How many per page?
$max = $feed->get_item_quantity(); // Where do we end?

?>

</div>		<?php endif; ?>

	$prevlink = '« Previous';
}

// Normalize the numbering for humans

<p>Showing <?php echo $begin; ?>–<?php echo $end; ?> out of <?php echo $max; ?> | <?php echo $prevlink; ?> | <?php echo $nextlink; ?> |
	</div>

</div></p>

Thanks in advance for any help you may give.
