how search between date using post in codeignitier - ajax

Question

Dear Expert need Help first see my view code in codeigniter :
<div class="form-group">
<label for="tglawal" class="col-sm-2 control-label">Periode</label>
<div class="col-sm-3">
<div class="input-group date">
<div class="input-group-addon">
<i class="fa fa-calendar"></i>
</div>
<input type="date" class="form-control" name="tglawal" id="tglawal">
</div>
</div>
<div class="col-sm-3">
<div class="input-group date">
<div class="input-group-addon">
<i class="fa fa-calendar"></i>
</div>
<input type="date" class="form-control" name="tglakhir" id="tglawal1">
</div>
</div>
</div>
and this my model code :
private function _get_datatables_query()
{
//add custom filter here
if($this->input->post('tglawal'))
{
$this->db->where('b.tglawal', $this->input->post('tglawal'));
}
if($this->input->post('tglakhir'))
{
$this->db->where('b.tglakhir', $this->input->post('tglakhir'));
}
}
public function get_datatables()
{
$this->_get_datatables_query();
if($_POST['length'] != -1)
$this->db->limit($_POST['length'], $_POST['start']);
$query = $this->db->get();
return $query->result();
}
and my controller if i get the important code is:
public function index()
{
$this->load->helper('url');
$this->load->helper('form');
$this->load->view('infokunjungan_view', $data);
}
else redirect(base_url());
}
public function ajax_list()
{
$list = $this->Infokunjungan->get_datatables();
$data = array();
$no = $_POST['start'];
foreach ($list as $infokunjungan) {
$no++;
$row = array();
$row[] = "<td style='vertical-align:middle'><center>{$no}<center></td>";
$row[] = "<td style='font-size:9px; vertical-align:left;'>{$infokunjungan->tglawal}<center></td>";
$row[] = "<td style='font-size:9px; vertical-align:left;'>{$infokunjungan->tglakhir}<center></td>";
$output = array(
"draw" => $_POST['draw'],
"recordsTotal" => $this->Infokunjungan->count_all(),
"recordsFiltered" => $this->Infokunjungan->count_filtered(),
"data" => $data,
);
//output to json format
echo json_encode($output);
}
the problem is if searching between two date tglawal and tglakhir
im using between 2016-12-04 and 2016-12-04 output display will empty
but if using between 2016-12-04 and 2016-12-06 output success where is my problem or maybe im using where or i have to use like?

Answer 1

You need to use the >= and <= operator.
In your model try the below.
if($this->input->post('tglawal'))
{
$this->db->where('b.tglawal >=', $this->input->post('tglawal')); //assuming this is your begining (from) date
}
if($this->input->post('tglakhir'))
{
$this->db->where('b.tglakhir <=', $this->input->post('tglakhir')); //assuming this is your end(to) date
}
The above will search for the between dates including the dates selected.
Use the operator depending on the beginning and ending variable.
