【中文标题】动态自定义过滤器在 codeigniter 中不起作用【英文标题】：Dynamic custom filter not working in codeigniter 【发布时间】：2017-03-05 17:24:08 【问题描述】：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。
谢谢
这是我的控制器

【问题讨论】：
“它不起作用” 是一个几乎毫无意义的问题陈述，尤其是当您向我们展示服务器端和客户端代码并且不隔离任何特定内容时。花几分钟回顾一下How to Ask 您好，感谢您的建议。我已经编辑了我的问题。我希望你能理解我的问题并帮助我解决我的问题。 【参考方案1】：也许回答晚了，但是看到这个链接希望能解决你的问题

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
