I have this RSS parsing code and it paginates , but only uses 'next' and 'previous' links instead of how google does it. I want it to read like this: first 1 2 3.... last
PHP Code: <?php require_once('simplepie.inc'); // Set your own configuration options as you see fit. $feed = new SimplePie(); $feed->set_feed_url(array( 'http://feeds2.feedburner.com/MishsGlobalEconomicTrendAnalysis', 'http://feeds.feedburner.com/TheBigPicture', 'http://feeds2.feedburner.com/ChartsAndCoffee', 'http://feeds.feedburner.com/typepad/tradeblogs/the_slope_of_hope_with_ti', )); $success = $feed->init(); // Make sure the page is being served with the right headers. $feed->handle_content_type(); // 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'] : 5; // How many per page? $max = $feed->get_item_quantity(); // Where do we end? // When we end our PHP block, we want to make sure our DOCTYPE is on the top line to make // sure that the browser snaps into Standards Mode. ?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US"> <head> <title>SimplePie: Demo</title> <link rel="stylesheet" href="styles.css" type="text/css" media="screen, projector" /> </head> <body> <div id="site"> <?php // If we have an error, display it. if ($feed->error()) { echo '<div class="sp_errors">' . "rn"; echo '<p>' . htmlspecialchars($feed->error()) . "</p>rn"; echo '</div>' . "rn"; } ?> <?php if ($success): ?> <?php // get_items() will accept values from above. foreach($feed->get_items($start, $length) as $item): $feed = $item->get_feed(); ?> <div class="chunk"> <h4><?php if ($item->get_permalink()) echo '<a href="' . $item->get_permalink() . '">'; echo $item->get_title(true); if ($item->get_permalink()) echo '</a>'; ?></h4> <p class="footnote">Source: <a href="<?php echo $feed->get_permalink(); ?>"><?php echo $feed->get_title(); ?></a> | <?putenv("TZ=US/Pacific"); echo $item->get_date('j M Y | g:i a'); ?></p> </div> <?php endforeach; ?> <?php endif; ?> <?php // Let's do our paging controls $next = (int) $start + (int) $length; $prev = (int) $start - (int) $length; // Create the NEXT link $nextlink = '<a href="?start=' . $next .

'">« Previous</a>'; } else if ($prev < 0) { $prevlink = '« Previous'; } // Normalize the numbering for humans $begin = (int) $start + 1; $end = ($next > $max) ? $max : $next; ?> <p>Showing <?php echo $begin; ?>–<?php echo $end; ?> out of <?php echo $max; ?> | <?php echo $prevlink; ?> | <?php echo $nextlink; ?> | <a href="<?php echo '?start=' . $start . '&length=5'; ?>">5</a>, <a href="<?php echo '?start=' . $start . '&length=10'; ?>">10</a>, or <a href="<?php echo '?start=' . $start . '&length=20'; ?>">20</a> at a time.</p> </div> </body> </html> |
