Server side paging with JqxGrid and Codeigniter - codeigniter

Question

I was trying to implement server side paging with JqxGrid and Codeigniter. I am following the tutorial here, http://www.jqwidgets.com/server-side-paging-with-jquery-grid/. I have a problem with posting pagenum and pagesize to Codeigniter controller. When I tried $this->input->get('') method, its not working.
Here is my Source for jqxgrid,
var source =
{
datatype: "json",
datafields: [
{ name: 'itemname'},
{ name: 'category'},
],
id: 'id',
url: '<?php echo base_url()."index.php/cart/reportgriddata/"; ?>',
root: 'Rows',
beforeprocessing: function(data)
{
source.totalrecords = data[0].TotalRows;
}
};
And in my controller, I used following method to get parameters from get-url of dataadapter
$pagenum =$this->input->get('pagenum');
$pagesize =$this->input->get('pagesize');
But here the values getting for both $pagenum and $pagesize is null.

Answer 1

Got it working by using POST method.
var source =
{
type:"POST"
datatype: "json",
datafields: [
{ name: 'itemname'},
{ name: 'category'},
],
id: 'id',
url: '<?php echo base_url()."index.php/cart/reportgriddata/"; ?>',
root: 'Rows',
beforeprocessing: function(data)
{
source.totalrecords = data[0].TotalRows;
}
};
and using,
$pagenum =$this->input->post('pagenum');
$pagesize =$this->input->post('pagesize');
