get value option in controllers

Hi, after 1 day I think that problem is not in form_open

($start_date) and ($end_date) get by sAjaxSource with ($v) in function

PHP Code:

function getrepairbyuser($pdf = NULL, $xls = NULL)
    {
        if ($this->input->get('start_date')) {
            $start_date = date('Y-m-d', strtotime($this->input->get('start_date'))) . " 00:00:00";
        } else {
            $start_date = date('Y-m-d 00:00:00');
        }
        if ($this->input->get('end_date')) {
            $end_date = date('Y-m-d', strtotime($this->input->get('end_date'))) . " 23:59:59";
        } else {
            $end_date = date('Y-m-d 23:59:59');
        } 


and I don't know how to send incule $status, $user_id  with $v  to (getrepairbyuser) ^^!

In view (sAjaxSource) is

PHP Code:

    $(document).ready(function () {

        $('.date').datepicker({ dateFormat: 'mm-dd-yy' });
        var oTable = $('#dynamic-table').dataTable({
            "aaSorting": [[0, "desc"]],
            "aLengthMenu": [[10, 25, 50, 100, -1], [10, 25, 50, 100, "All"]],
            "iDisplayLength": 10,
            'bProcessing': true, 'bServerSide': true,
            'sAjaxSource': '<?= site_url('panel/reports/getrepairbyuser/?v=1' . $v) ?>',
            'fnServerData': function (sSource, aoData, fnCallback) {
                aoData.push({
                    "name": "<?= $this->security->get_csrf_token_name() ?>",
                    "value": "<?= $this->security->get_csrf_hash() ?>"
                });
                $.ajax({'dataType': 'json', 'type': 'POST', 'url': sSource, 'data': aoData, 'success': fnCallback});
            }, 
            "aoColumns": [
            null,
            null,
            null,
            null,
            null,
            null,
            {mRender: formatToMoney},
            ],
            "fnFooterCallback": function (nRow, aaData, iStart, iEnd, aiDisplay) {
                var gtotal = 0;
                for (var i = 0; i < aaData.length; i++) {
                    gtotal += parseFloat(aaData[aiDisplay[i]][6]);
                }
                var nCells = nRow.getElementsByTagName('th');
                nCells[6].innerHTML = formatMoney(parseFloat(gtotal));
            }
           
        });
    });
