Question

我有这个project表，你可以在下面看到，从下表我想制作一个图表，其中包含当月有多少project

id | project_name | start_date |
1  | proj1        | 2017-09-01 | 
2  | proj2        | 2017-09-01 |
3  | proj3        | 2017-09-01 |
4  | proj4        | 2017-08-01 | 
5  | proj5        | 2017-08-01 |

我到目前为止所做的是制作一个模型，然后我很困惑接下来应该做什么，因为我创建的模型不是动态的，它只读取某个月的情况month = 09

public function get_monthly_totals($theYear = '', $theMonth = '')
{
    $select = "
        SELECT COUNT(*) AS start_count
        FROM
           project
        WHERE 
           MONTH(start_date)=09";
    return $this->db->query($select);
}

我想制作一张上面的图表，我使用的插件是 highcharttable ，它将html表数据转换为图表，我是如何制作类似的东西，我如何制作一个月的即使没有数据，也存在如何将数据连接到正确的月份？

我设法通过在我的控制器中做这样的事情来做到这一点，我知道这不是很漂亮，但现在还可以。

public function dashboard_project()
{   
    $thn = $this->input->post('tahun');
    $id = md5($this->session->userdata('id'));
    $data['rows'] = $this->pengguna_m->getPengguna($id)->row();

    $data['januari'] = $this->dashboard_m->get_kategori_totals('01',$thn)->num_rows();
    $data['februari'] = $this->dashboard_m->get_kategori_totals('02',$thn)->num_rows();
    $data['maret'] = $this->dashboard_m->get_kategori_totals('03',$thn)->num_rows();
    $data['april'] = $this->dashboard_m->get_kategori_totals('04',$thn)->num_rows();
    $data['mei'] = $this->dashboard_m->get_kategori_totals('05',$thn)->num_rows();
    $data['juni'] = $this->dashboard_m->get_kategori_totals('06',$thn)->num_rows();
    $data['juli'] = $this->dashboard_m->get_kategori_totals('07',$thn)->num_rows();
    $data['agustus'] = $this->dashboard_m->get_kategori_totals('08',$thn)->num_rows();
    $data['september'] = $this->dashboard_m->get_kategori_totals('09',$thn)->num_rows();
    $data['november'] = $this->dashboard_m->get_kategori_totals('10',$thn)->num_rows();
    $data['oktober'] = $this->dashboard_m->get_kategori_totals('11',$thn)->num_rows();
    $data['desember'] = $this->dashboard_m->get_kategori_totals('12',$thn)->num_rows();

    $data['title']= 'Aplikasi Saranabudi';
    $data['aktif']  = 'Jumlah Kategori Project';
    $data['judul_hal']= 'Dashboard Kategori Project';

    $this->load->view('layout/header',$data);
    $this->load->view('layout/sidebar',$data);
    $this->load->view('dashboard/pelanggan/home');
    $this->load->view('layout/footer');
}

这是我一年内每月计算的简单语法

public function get_monthly_totals($theYear = ''){
    $select = "
        SELECT 
          COUNT(*) AS start_count,
          MONTH(start_date) as month
        FROM
           project
        WHERE 
           YEAR(start_date)='$theYear'
        GROUP BY
           MONTH(start_date)
    ";
    return $this->db->query($select);
}
