Value name "user_id" and "status" cannot get in controllers. Try assign $user_id ='1', $status ='1' in controllers if clause work ok.

Sorry my english not good and this code not mine, i try edit it 
Thanks so much 

The controller function that should get the values for user_id and status is getrepairbyuser().
The form in your view points to the function: repairbyuser().
This way, the post values won't reach the right function.

Please, use the php code button on the button bar of the forum editor next time.

PHP Code:

<?php 
public function repairbyuser()
{

} 


This is much better than plain text.

Thanks U. I edited first post 
This code not mine, i try to edit but i don't know why with getrepairbyuser(), (start_date and end_date) of date_range get value in controllers. But use 

PHP Code:

($this->input->get('start_date') 


not is 

PHP Code:

($this->input->post('start_date') 


getrepairbyuser() use for generate datatable,

I'm newbie with CI ^^!

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));
            }
           
        });
    }); 


^^!

Hiii, problem has been fixed

add more value for $v  in View

PHP Code:

$st = $this->input->post('status');
$ui = $this->input->post('user_id');
$v = "";
if ($this->input->post('date_range')) {
    $dr = explode(' - ', $this->input->post('date_range'));
    $v .= "&start_date=" . $dr[0];
    $v .= "&end_date=" . $dr[1];
    $v .= "&status=" .$st;
    $v .= "&user_id=" .$ui;
} 


then in controlles, get value by method get

PHP Code:

$user_id = $this->input->get('user_id');
$status  = $this->input->get('status'); 


it work, only one $v send 4 value to controllers in function getrepairbyuser
