动态自定义过滤器无法在codeigniter中工作

Question

我有自定义过滤器和数据表的codeigniter形式。我正在使用jquery，ajax来加载数据。我期望的是，例如，当我选择公司列表时，我只想选择加载到数据表中的公司。但现在发生的情况是数据表中的所有数据加载，就好像没有过滤器一样。请帮忙。

感谢

这是我的控制器

也许可以回答晚了，但看这个链接希望可以解决问题乌尔

http://mbahcoding.com/tutorial/php/codeigniter/codeigniter-server-side-datatables-custom-filter.html

public function index() 
    { 
     $this->load->helper('url'); 
     $this->load->helper('form'); 

     $list = $this->assetfiltermdl->get_listkary(); 

     $opt = array('' => 'All List Karyawan'); 
     foreach ($karyawans as $karyawan) { 
      $opt[$karyawan] = $karyawan; 
     } 

     $data['form_karyawan'] = form_dropdown('',$opt,'','id="karyawan" class="form-control"'); 
     $this->load->view('karyawan_view', $data); 
    } 

我希望这可以解释我们的代码
