php script editing help require for joomla

[Raji]

Hello there,

I am running a script at my site to display books. Here is the output

http://baask.com/diwwan/index.php?page=kuntagani_sapar

I m fully satisfied with that script but now issue is that I have to move these pages from simple portal to joomla (www.baask.com/home)

My script is working okay at joomla too but the page url is wrong.

I need help to edit this script and make it usable for joomla too.

<?php
// You can place PHP like this
global $scripturl;

$num_pages = 173;
$cover_image_url ="http://baask.com/literature/abid_askani/rushnoo/rushnoo.jpg";

$page_image_url = "http://baask.com/literature/abid_askani/rushnoo/0%s.gif";

if (empty($_GET['number']) || $_GET['number'] < 1 || $_GET['number'] > $num_pages)
{
 $current_page = 0;
 $image_url = $cover_image_url;
}
else
{
 $current_page = (int) $_GET['number'];

$image_url = sprintf($page_image_url, ($current_page>9 ? '' : '0') . $current_page);
}

echo '

<div style="text-align: center;">
Page ', $current_page, ' of ', $num_pages, '
<p><img src="', $image_url, '" alt="', $current_page, '" /></p>';

for ($i = 0; $i <= $num_pages; $i++)
 echo '
<a href="', $scripturl, '?page=rushnoo;number=', $i, '">', ($i == $current_page ? '<strong>[' : ''), ($i == 0 ? 'Cover' : $i), ($i == $current_page ? ']</strong>' : ''), '</a>';

echo '

<a href="http://baask.com/diwwan/index.php?topic=6722">Click for Comments and feedback </a>;

</div>';
?>

Looking forward

Raji
