Question

我目前在总计方面遇到问题。好吧，我有3张不同的桌子。 billing_payments ， billing_entry 和服务。

我的问题是，我无法获得每个服务的总数。我提供了一个截图，以便你明白我的意思。

以下是报告的代码。我添加了一些注释来指出问题的开始和结束位置。

如果您查看自己的图片，可以清楚地看到您从最后一行（350, zero, 350, 485, 485, 485, zero, 15, 300）的列（绿色框中）输出每个值

您可以通过添加占位符变量来计算每项服务的总数，例如：

foreach ($quer->result() as $service) {   // you want to output one <td> per service, so the <td> should be printed at the end of this foreach
  $serviceTotal = 0; // initialize the total for each service                                                          
  $totserv = $this->db->query('SELECT * FROM `billing_payments` WHERE (`date` BETWEEN "'.$this->input->get('from').'" AND "'.$this->input->get('to').'")');                                                                                    
  foreach ($totserv->result() as $servdata) {
  $id = $servdata->id;   

      $this->db->where('billing_id', $servdata->billing_id);  
      $this->db->where('billing_serviceid', $service->service_id);                                   
      $this->db->select_sum('billing_amount');
      $medsup = $this->db->get('billing_entry');
      foreach ($medsup->result() as $med) {
          $serviceTotal = $serviceTotal + $med->billing_amount     
      }
  }
  echo '<td class="bg-success">'. $serviceTotal .'</td>';
}

通过这种方式，您将获得每项服务一项，$serviceTotal变量将包含该特定服务的每个订单项的总和。

您也可以使用更有效的选项 - 首先，您可以在服务代码块中获取个别总计时计算个别总数，例如：

$serviceTotals = array(); // a holder for all the totals
foreach ($servicesquery->result() as $service) {                                     
    $this->db->where('billing_serviceid', $service->service_id);
    $this->db->where('billing_patientid', $data->patient_id);
    $this->db->where('billing_id', $data->billing_id);
    $this->db->select_sum('billing_amount');
    $billing = $this->db->get('billing_entry');
    foreach ($billing->result() as $bill) {
      $serviceTotals[$service->service_id] = $serviceTotals[$service->service_id] + $bill->billing_amount; //this updates the total for each service ID
      echo '<td>'.$bill->billing_amount.'</td>';
    }
}

然后，您可以遍历此数组以输出每个总数。

理想情况下，您还应该考虑在控制器中计算所有这些值，这些值可以从模型中调用所需的查询，然后将这些数据打包到$data变量中。然后控制器可以将所有这些传递给您的视图。 CodeIgniter有很多很好的资源来解释模型 - 视图 - 控制器（MVC）模式（这个问题超出了这个问题的范围），并且在没有实现MVC模式的情况下使用CI使网络上的CI大部分文档和支持变得更加困难。
