if (restore) selObj.selectedIndex=0;
}
//-->
</script>
<?php

$page_url = 'managepageuser.php';
$display_per_page = constant("DISPLAYPERPAGE");

if(isset($_GET['pages']) && $_GET['pages']!="1")
{
$pages = $_GET['pages'];
$from_limit = ($pages-1) * $display_per_page;
$to_limit = $from_limit + $display_per_page;
}
else
{
$pages = 1;
$from_limit = 10;
$to_limit = $from_limit + $display_per_page;
}

if($to_limit > $num_lists)
{
$to_limit = $num_lists;
}


if($num_lists > 0)
{
$total_pages = intval($num_lists / $display_per_page);
if($total_pages!='0')
{
if(($num_lists % $display_per_page) !='0') { $total_pages = $total_pages +1; }
}
$prev = $pages - 1;
$next = $pages + 1;
$first = 1;
$last = $total_pages;
$pages_cnt = 1;
if($total_pages > $pages_cnt)
{
$paging_txt .= "<a href='$page_url?pages=$first'>&laquo;&laquo; FIRST</a> | ";
if($pages >1) { $paging_txt .= " <a href='$page_url?pages=$prev'>&laquo;PREVIOUS</a> | "; }
$paging_txt .= "<select name=\"menu1\" onchange=\"MM_jumpMenu('parent',this,0)\">";

while($pages_cnt <= $total_pages)
{

$paging_txt .= "<option value='".$page_url."?pages=".$pages_cnt."'";
if($pages_cnt == $_GET['pages']) { $paging_txt.= "selected"; }
$paging_txt.= ">".$pages_cnt."</option>";
$pages_cnt++;
}

$paging_txt .= "</select>";
