Paginator Issue

Hi,


I have applied this paging script in one of my application. But i am facing a problem. Suppose i have two pages search.php & searchresult.php.

In search.php i have given user to search for assignments in category.

This data is posted to searchresult.php in which i have applied the pagination script.

My code of searchresult.php

if($_POST['cmbSearchin']=='category' && $_POST['rdbFor']=='assignment')
{
$sqlForCategories = "
SELECT
tbl_categories.title as categorytitle,
tbl_categories.pk_categoryid as categoryid,
count(tbl_assignments.pk_assignmentid) as totalassignments
FROM
tbl_categories
LEFT JOIN tbl_assignments
on ( tbl_categories.pk_categoryid = tbl_assignments.fk_tbl_categories_categoryid )
WHERE
tbl_categories.title LIKE '%".$_POST[txtSearchString]."%'
GROUP BY
categoryid
";
$categories=$objdb->customQuery($sqlForCategories, false);
if($categories)
{
foreach($categories as $category)
{
$categoryid.=$category[categoryid].",";
}
$categoryid=trim($categoryid,',');
$sqlforAssignments="
SELECT
tbl_categories.title as category,
tbl_assignments.title,
tbl_assignments.pk_assignmentid as assignmentid,
tbl_assignments.description,
tbl_assignments.location,
tbl_assignments.type
FROM
tbl_assignments
INNER JOIN
tbl_categories
ON (tbl_assignments.fk_tbl_categories_categoryid = tbl_categories.pk_categoryid)
WHERE
tbl_assignments.fk_tbl_categories_categoryid IN (".$categoryid.")";
require_once(APP_PHYSICAL_PATH."classes/paging.php");
$paging = new PAGING($sqlforAssignments,10,3);
$sqlforAssignments = $paging->sql;
$assignments = $objdb->customQuery($sqlforAssignments,false);
$assignments = cleanValues($assignments);
}

}



and echo $paging->show_paging(APP_URL."views/searchresult.php", $params);

Suppose i have 15 records, firstly 10 records are displayed & then there is a link for page 2. Clicking on this displays blank page instead of 5 records.

How can i pass the post variables to $params and $sqlforAssignments is a join query, i am not sure it will work or not?

Please help

Thanks,
Pankaj
