Question

我是这样的控制者

function view()
    {
        if($this->tank_auth->get_user_role_id() == 1){
            $users = null;
        }else{
            $users = $this->_get_users_id();
        }
        //count total rows of transaction list
        $this->db->where('user_id',$users);
        $this->db->from('book_packages');
        $config['base_url'] = base_url().'index.php/transaction/view';
        $config['total_rows'] = $this->db->count_all_results();
        $config['per_page'] = 10;
        $config['uri_segment'] = 3;
        $config['num_links'] = 1;

        /* this is config tag */

        $this->pagination->initialize($config);
        $data['total_rows'] = $config['total_rows'] ;
        $data['title'] = 'List transaction';
        $data['text'] = $this->transaction_model->view_transaction($config['per_page'],$this->uri->segment(3),$users);
        $data['pagecontent'] = "admin/view_transaction";
        $this->load->vars($data);
        $this->load->view('template');

    }

我在视图$this->pagination->create_links();中回应了这一点当我加载控制器时，我得到了像这样的错误

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Transaction::$pagination

Filename: controllers/transaction.php

Line Number: 804

Fatal error: Call to a member function initialize() on a non-object in my directory

我不知道为什么，我已经加载了图书馆分页，帮助网址，带有资本的班级名称。当我将代码上传到托管时，它就会发生，但是当我在localhost中加载它时，我没有收到任何错误。

任何帮助都非常感谢。非常感谢你。

function view()
    {
        if($this->tank_auth->get_user_role_id() == 1){
            $users = null;
        }else{
            $users = $this->_get_users_id();
        }
        //count total rows of transaction list
        $this->db->where('user_id',$users);
        $this->db->from('book_packages');
        $config['base_url'] = base_url().'index.php/transaction/view';
        $config['total_rows'] = $this->db->count_all_results();
        $config['per_page'] = 10;
        $config['uri_segment'] = 3;
        $config['num_links'] = 1;

        /* this is config tag */


        /*THIS IS MISSING*/
        $this->load->library('pagination');




        $this->pagination->initialize($config);
        $data['total_rows'] = $config['total_rows'] ;
        $data['title'] = 'List transaction';
        $data['text'] = $this->transaction_model->view_transaction($config['per_page'],$this->uri->segment(3),$users);
        $data['pagecontent'] = "admin/view_transaction";
        $this->load->vars($data);
        $this->load->view('template');

    }

Answer 2

错误消息表明$this->pagination未定义。您在哪里定义（比方说）$this->pagination = new Pagination()？显然，new Pagination必须由您的分页库的名称替换。

Answer 3

尝试将自动加载脚本放在控制器开头的_construct（）上。

必须是这样的：

public function __construct（）{

      parent:: __construct();
      $this->load->library("pagination");

}

然后在你的方法上，首先尝试初始化你的$ config：

$ config = array（）;

$ config [＆＃39; base_url＆＃39;] = base_url（）。＆＃39; index.php / transaction / view＆＃39;;

$ config [＆＃39; total_rows＆＃39;] = $ this-＆gt; db-＆gt; count_all_results（）;

$ config [＆＃39; per_page＆＃39;] = 10;

$ config [＆＃39; uri_segment＆＃39;] = 3;

$ config [＆＃39; num_links＆＃39;] = 1;

或者，如果您确实包含了“分页”，请再次检查config / autoload.php下的自动加载文件。在$ autoload [＆＃39; libraries＆＃39;]

致命错误：调用成员函数initialize（）
