【问题描述】：

我试图将已付金额和折扣金额添加到费用类型行，但如果仍未支付，它会针对每个费用类型行重复。

代码：

        ->order_by('a1.given_date', 'desc')
        ->get();
        $result = $query->result();
        
        return $result;
    }
    
    
    public function paidInstallments($company_id){

            $result = $query->result();
            return $result;
    }

我通过添加条件尝试了多种方式，但我无法得到完美的答案，请帮我解决这个错误，在图像中第一行仍未支付但支付金额不等于零，我需要这个如果未付款，则行需要为零。在此先感谢

    【解决方案1】：

    不确定我是否理解您的问题，但如果您希望未付行上的金额为 0。你可以使用这样的东西：

    我添加了这个：

    $amount_shown = $value->amount;
if (((int)$value->balance)==(int)($value->amount)) {
    $amount_shown = 0;
}

    并将其添加到您的表中：

    <td><?php echo $amount_shown ?></td>

    【讨论】：

    • 这对我有用，可以使未支付的行保持为零，但在总行 (tfoot) 中，已支付的总金额大于总金额，请参阅上图。
    • 更新的代码，一切正常，但每个费用类型行的总支付金额附加到所有其他费用类型行，例如，如果第一行有总余额 9000 并且我支付了 1000，如第二行总余额为 5000 的行，我支付了 3000，在第 2 行，支付的金额没有准确显示 3000，它与第一行的支付金额相加并显示 4000，如果你不能，我希望它只显示 3000要了解我的台词，请参考我附有问题的图片，感谢您的支持和耐心。
    【解决方案2】：

    现在可以正常使用了，我只需按余额 id 将所有已付金额组的总和相加即可。

    控制器：

    public function issueAdvance($company_id){
        if($this->session->userdata("is_active") == 1){

          $seedIssue =$this->seed_issue_model->selectFarmer($company_id);
          $singlefarmer =$this->seed_issue_model->selectIssueDates($company_id);
          $crops = $this->seed_issue_model->get_crop_data(); //Crop
          $pc_code = $this->seed_issue_model->get_pc_data(); //Production-Code
          $advance_amount =$this->advance_model->getLoanData($company_id);
          $paid_installments = $this->advance_model->paidInstallments($company_id);
          $total_paid_amount = $this->advance_model->paidAmount($company_id);
        // echo '<pre>'; print_r($total_paid_amount); echo ("</pre>"); exit();
          if ($this->input->server('REQUEST_METHOD') == "GET") {
                $data = array(
                  "page_content" => "advance/view_advance_issue",
                  "singleFarmer" =>$singlefarmer,
                  "issueSeed"  =>$seedIssue,
                  "crop_result" =>$crops,
                  "pc_result" =>$pc_code,
                  "farmer_loan" =>$advance_amount,
                  "paid_installments" =>$paid_installments,
                  "rowpaidAmount" =>$total_paid_amount
                );
                $this->load->view("layout/main_layout",$data);
            }
            else{
                return false;
            }
        }
    }

    型号：

       public function paidAmount($company_id){
        $query = 
            $this->db->select('(SELECT SUM(p1.amount_paid)) as amount_paid,(SELECT SUM(p1.amount_discount)) as amount_discount,p1.balance_id')
                ->from('tbl_pay_amount as p1')
                ->join('tbl_balance as b1', 'p1.balance_id=b1.balance_id') 
                ->group_by('b1.balance_id')
                ->where("p1.farmer_id", $company_id)
                ->get();
                return $query->result();
    }

    查看：

    <?php
                $total_amount = 0;
                $total_discount_amount = 0;
                $total_balance_amount = 0;
                $total_paid_amount = 0;
                
                foreach ($farmer_loan as $key => $balance) {
                    $discount_amount = 0;
                    $paid_amount = 0;
                    $total_amount = $total_amount + $balance->amount;
                }           
                 foreach ($farmer_loan as $index => $value) {    
                    $balance_amount = $value->balance;
                    $total_balance_amount = $total_balance_amount + $balance_amount;
                    $total_discount_amount = $total_discount_amount + $discount_amount;

                    foreach ($rowpaidAmount as $index => $pvalue) {                        
                        if(($pvalue->balance_id != $value->balance_id))
                            continue;
                         $discount_amount =$pvalue->amount_discount;
                        $paid_amount = $pvalue->amount_paid;
                        $total_paid_amount = $total_paid_amount + $paid_amount;

                    }
           ?>
