Fatal error: Call to a member function base_url() on a non-object Codeigniter

Question

Fatal error: Call to a member function base_url() on a non-object

当我从支付网关重定向到该站点时出现上述错误，因此包含所有脚本的头文件未加载

我尝试使用 $ci =& get_instance(); 但仍然出现同样的问题

public function payment_success() { 
    $this->load->model("bidding_m"); 
    $this->load->model("admin_setting_m"); 
    $this->load->model("channel_partners_m"); //call model functions to update the tables 
    $this->load->config('payu_config', TRUE); 
    $this->config = $this->config->item('payu_config'); 
    //echo base_url();
    exit;
}

Answer 1

您可以尝试像这样加载助手

文件名首字母大写

Somelibraryname.php

<?php

class Somelibraryname  {

  public function __construct() {
    $this->CI =& get_instance();
    $this->CI->load->helper('url');
  }

  public function something() {
    echo base_url();

    // Or

    echo $this->CI->config->item('base_url');
  } 

}

Answer 2

你的问题是这一行：

$this->config = $this->config->item('payu_config');

我不知道这段代码是否在库/控制器中，所以我尝试对两者进行解释：

控制器：

您用一个配置项重写了整个配置（$this->config = ...），您的 base_url 配置项丢失了！所以这样做：

$config = $this->config->item('payu_config');

图书馆：

您正在访问配置项，但没有 codeigniter 实例。如果此代码在库中，它应该如下所示：

public function payment_success() { 
    $ci = & get_instance();
    $ci->load->model("bidding_m"); 
    $ci->load->model("admin_setting_m"); 
    $ci->load->model("channel_partners_m"); 
    $ci->load->config('payu_config', TRUE); 
    //if you have in this library variable $config
    $this->config = $ci->config->item('payu_config'); 
    echo base_url();
    exit;
}
