The searchfilter i make didn’t fetch the data i want to search

I’m adding a search filter in my system but it won’t search.Please someone tell Me the problem with my coding.

Controller

public function facility_reservation_view(){
            $name = $this->input->post('name');
            $searchtype  = $this->input->post('searchtype');
            $datefrom  = $this->input->post('datefrom');
            $dateto  = $this->input->post('dateto');
            $status = $this->input->post("status");

            $query = $this->model_facility->facility_reservation_table($name, $status, $searchtype, $datefrom, $dateto);
        echo json_encode($query);
    }

Model
