我的网络应用程序功能被困在我的网站上，我有4个用于过滤数据的菜单过滤器，fungsi_bangunan，jenis_bangunan完全正常工作，desa / kelurahan很好，因为我在json中使用javascript填充了数据当我选择kecamatan然后选择desa / kelurahan正在努力，但是当我使用kecamatan过滤器数据没有显示时，我认为查询构建器是正确的但是我找不到关于这个我的问题的错误，所以也许你们可以帮助我，解决方案是什么，我为我的项目使用php和codeigniter框架，
这里是型号代码：
public function filter_data($filter) {
$this->db->like('jenis_kegiatan',$filter);
$this->db->or_like('fungsi_bangunan',$filter);
$this->db->or_like('kecamatan',$filter);
$this->db->or_like('desa_kel',$filter);
$query = $this->db->get('permo_pdrt');
return $query->result();
}
和控制器：
public function filterkeyword() {
$filter = $this->input->post('filter');
$data['results'] = $this->model->filter_data($filter);
$this->load->view('result_view',$data);
}
和此视图过滤器：
