【问题描述】：

我用 dompdf 以 pdf 的形式打印了账单，账单上有总账单。但是总账单的结果是把bulan_bill中包含的所有付款数据加起来，总账单应该只加起来没有支付的款项。所以我想制作一个总账单，将bulan_status = 0的bulan_bill上的数据相加。

控制器中的代码：

 function printBill() {
    $this->load->helper(array('dompdf'));
    $f = $this->input->get(NULL, TRUE);

    $data['f'] = $f;

    $siswa['santri_id'] = '';
    $params = array();
    $pay = array();
 
// School Year
    if (isset($f['n']) && !empty($f['n']) && $f['n'] != '') {
      $params['period_id'] = $f['n'];
      $pay['period_id'] = $f['n'];
    }

// Student
    if (isset($f['r']) && !empty($f['r']) && $f['r'] != '') {
      $params['santri_room'] = $f['r'];
      $siswa = $this->Santri_model->get(array('santri_room'=>$f['r']));

    }
    $pay['santri_id']=$siswa['santri_id'];
 
    $data['period'] = $this->Period_model->get($params);
    $data['siswa'] = $this->Santri_model->get(array('santri_id'=>$siswa['santri_id'], 'group'=>TRUE));
    $data['bulan'] = $this->Bulan_model->get($pay);
    $data['bebas'] = $this->Bebas_model->get($pay);
 
    $data['setting_district'] = $this->Setting_model->get(array('id' => SCHOOL_DISTRICT)); 
    
    
    $html = $this->load->view('payout/payout_bill_pdf', $data, true);
    $data = pdf_create($html, $siswa['santri_full_name'], TRUE, 'A4', TRUE);
  }

【解决方案1】：

如果您在查询中添加以下内容，问题将得到解决；

$this->db->where('bulan_status', '0');

【讨论】：

function get_total_bulan ($params = array()){ if(isset($params['bulan_bill'])) { $this->db->where('bulan_bill'); $this->db->where('bulan_status', '0'); }} 是这样的吗？
是或函数 get_total_bulan ($params = array()){ if(isset($params['bulan_bill'])) { $this->db->where('bulan_bill'); $this->db->where('bulan_status', 0); }}
