Convert this code into a google like pagination

johnsonsmith1 · 11-16-2009, 12:09 AM

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
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.

Have you tried doing any of it on your own?

I found this code online and tried adding it to my original code, but nothing changes.
I have spent a couple hours searching for pagination scripts but I cant get any off them to work with my site. I'm not using mysql a database but RSS.

PHP Code:


			
******  build the pagination links ******/

// range of num links to show

$range = 3;



// if not on page 1, don't show back links

if ($currentpage > 1) {

   // show << link to go back to page 1

   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";

   // get previous page num

   $prevpage = $currentpage - 1;

   // show < link to go back to 1 page

   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";

} // end if



// loop to show links to range of pages around current page

for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {

   // if it's a valid page number...

   if (($x > 0) && ($x <= $totalpages)) {

      // if we're on current page...

      if ($x == $currentpage) {

         // 'highlight' it but don't make a link

         echo " [<b>$x</b>] ";

      // if not current page...

      } else {

         // make it a link

         echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";

      } // end else

   } // end if

} // end for

                 

// if not on last page, show forward and last page links       

if ($currentpage != $totalpages) {

   // get next page

   $nextpage = $currentpage + 1;

    // echo forward link for next page

   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>></a> ";

   // echo forward link for lastpage

   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>>></a> ";

} // end if

/****** end build pagination links ******/
