我有一个带有自定义过滤器和数据表的codeigniter表单。我正在使用jquery，ajax来加载数据。我所期望的是，当我选择公司列表时，我只想选择加载数据表的公司。但现在发生的是数据表中的所有数据加载，好像没有过滤器一样。请帮忙。
谢谢
这是我的控制器

也许可以回答很晚但是看到这个链接希望可以解决你的问题
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);
}
我希望这可以解释你的代码
