在codeigniter + d3.js图表​​

Question

我想按日期范围+公司名称过滤我的MSQL数据。 我可以完美地获得具有日期范围的图表。 我目前的问题是我也会按公司名称过滤。 我无法按组列出公司并进行过滤 公司名称+日期范围。 有人可以查看我的代码，请给我帮助。谢谢！

我的控制器

public function get_chart_data() {

        if (isset($_POST['start']) AND isset($_POST['end'])) {
        $start_date     = $_POST['start'];
        $end_date       = $_POST['end'];
        $company_name   = $_POST['company_name'];
        $results = $this->chart_model->get_performance($start_date, $end_date, $company_name);

        if ($results === NULL) {

        echo json_encode('No record found');

        } else {

        print_r(json_encode($results));

        }

        } else {
        echo json_encode('Date must be selected.');
        }


    }

我的观点

//company select
<select name="company_name" onchange="showdrop()" id="company_name">
//company list
</select>


//Sugar moment and Date Picker display
 <input type="text" name="range" id="range"></a>

//Graph display
<figure id="chart"></figure>
