Codeigniter 如何在使用instamojo和codigniter成功付款后更新数据库中的付款状态

我正在使用instamojo支付集成与codeigniter，我面临以下错误

已正确插入付款请求数据，但我想更新付款 付款成功后的状态

未在库中创建webhook url

在CI控制器中编写的instamojo webhook代码如下：

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

public function __construct()
{
parent::__construct();
$this->load->helper('url'); // helper load
}     
public function payment_webhook(){
        $data = $_POST;
        $mac_provided = $data['mac'];  
        unset($data['mac']); 
        $ver = explode('.', phpversion());
        $major = (int) $ver[0];
        $minor = (int) $ver[1];
        if($major >= 5 and $minor >= 4){
             ksort($data, SORT_STRING | SORT_FLAG_CASE);
        }
        else{
             uksort($data, 'strcasecmp');
        }


        $mac_calculated = hash_hmac("sha1", implode("|", $data), "our Salt key updated here");
        if($mac_provided == $mac_calculated){
            if($data['status'] == "Credit"){

                echo "successful";

            }
            else{
                echo "unsuccessful";

            }
        }
        else{
            echo "MAC mismatch";
        }
  }

  }

尝试

$this->load->helper（'url'）在instamojo库或Autolodi中尝试了$this->load->helper（'url'）；同样的问题好吧，你在函数payment\u webhook（）中得到了多少？或者根本没有？是否有任何错误消息？尝试使用例如
echo（'io'）进行调试；死亡要在填写金额、手机等时发现导致错误的行，我再次单击提交按钮页面重新加载并显示当前页面显示
public function pay_payment($purpose,$amount,$member_name,$member_mobile,$member_email,$redirect_url){

        $ch = curl_init();

        $data = json_decode($response, TRUE);

        if(isset($data['success']) && $data['success'] === true)
        {

             $transaction=$data['payment_request'];
        $result=$this->CI->db->insert('ag_payment',$transaction);
          // if($result==="TRUE"){
            $site = $data['payment_request']['longurl'];
            redirect($site, 'refresh');
          // }
        }

         }
