This is working code

$params['toDate'] = $this->input->post('toDate', TRUE);
$params['fromDate'] = $this->input->post('fromDate', TRUE);$this->load->model('your_model');
$this->load->library('form_validation');
$this->form_validation->set_data($params);

$startDate = strtotime($params['fromDate']);
$endDate = strtotime($params['toDate']);

if ($endDate >= $startDate):
    $this->form_validation->set_rules('fromDate', 'From Date', 'required|trim');
    $this->form_validation->set_rules('branchCode', 'Branch Code', 'required|trim');
else:
    $json = array(
        "success" => false,
        "msg" => "Start date must be greater than end date"
    );

    echo json_encode($json);
    die();
endif;

Try this. It is by using CI validation library. It uses callback type of validation.

Put this in if(isset($_POST['submit_button_name'])) {} section. First, load validation array,

$validation = array(
  array('field' => 'startDate', 'label' => 'StartDate', 'rules' => 'required|callback_compareDate'),
  array('field' => 'endDate', 'label' => 'endDate', 'rules' => 'required|callback_compareDate'),
);

Then load CI validation library as,

$this->form_validation->set_rules($validation);
$this->form_validation->set_message('required', '%s is required.');

This is the called back function.

function compareDate() {
  $startDate = strtotime($_POST['startDate']);
  $endDate = strtotime($_POST['endDate']);

  if ($endDate >= $startDate)
    return True;
  else {
    $this->form_validation->set_message('compareDate', '%s should be greater than Contract Start Date.');
    return False;
  }
}

The "required" validation makes the fields mandatory to be filled with something. The callback function, in this case, compares the dates, and further processes the form if start date is less than from date OR flags error otherwise.

Meanwhile, if you want in Jquery you can use this.

var startDate = new Date($('#startDate').val());
var endDate = new Date($('#endDate').val());

if (startDate > endDate){
       alert("Start Date should be less than End Date");
       return false;
}
