将总金额保存在我的表中（codeigniter）

Question

这里是 codeigniter 的新手。如何在每个用户的表中保存我的总金额？我所做的唯一一件事就是总结它并在我的视图中展示它。我的目标是将总佣金保存在我的“agent_commission”表“上。我提供了我的目标的屏幕截图，以便更好地可视化。提前谢谢您。任何帮助将不胜感激。

<?php $formattedNum = number_format($commCurrentBalance, 2);
                            echo $formattedNum;
                            ?

控制器：

public function commi()
    {
        $data['activeNav'] = "";
        $data['subnav'] = "commissions";
        $this->header($data);
        $this->nav();
        $data['currentPoints']=$this->session->userdata('currentPoints');
        $data['result'] = $this->commissions->get1();
        $data['commCurrentBalance']=$this->load->commissions->gettotalcommi(); //getting sum of amount
        $this->load->view('comm_view', $data);
        
        $this->footer();
    }

型号：

function gettotalcommi(){
        $reqcommi= $this->session->userdata('uid');
        
        $this->db->select_sum('amount');
        $this->db->where('commTo',$reqcommi);
        $result = $this->db->get('agent_commission_history')->row();
        
        return $result->amount;
    }

Answer 1

我不确定它是否有效，但请尝试一下

$db->select_sum('amount');
$db->where('commTo',$param);
$aq = $db->get_compiled_select('agent_commission_history');

$db->set('commCurrentBalance',"($aq)",false);
$db->where('commTo',$param2);
$db->update('agent_commission');

这相当于我之前发布的查询的 Codeigniter：

UPDATE agent_commission 
SET commCurrentBalance = ( SELECT SUM(amount) FROM agent_commission_history WHERE commTo = ?) 
WHERE commTo = ?

Answer 2

public function commi(){
 $data['commCurrentBalance']=$this->load->commissions->gettotalcommi(); //getting sum of amount
 
$dataArray = array(
        'commCurrentBalance'=>$data['commCurrentBalance']
        );
 
 $this->db->insert('agent_commission',$dataArray);
 
 $this->load->view('comm_view', $data);
        
        $this->footer();
    }
