codeigniter登录页面不会重定向到仪表板

Question

我在名为“pages.php”的控制器文件中出现问题。通过具有正确凭据的登录页面登录后，pages.php无法打开仪表板。我怀疑这个问题的来源可能是在 pages.php

中找到的

<?php 
class Pages extends MY_Controller
{
public function view($page = 'login')
{
    if (!file_exists(APPPATH.'views/'.$page.'.php'))
    {
        // Whoops, we don't have a page for that!
        show_404();
    }

    $data['title'] = ucfirst($page); // Capitalize the first letter

    if($page == 'section' || $page == 'subject' || $page == 'student' || $page == 'marksheet' || $page == 'accounting') {
        $this->load->model('model_classes');
        $data['classData'] = $this->model_classes->fetchClassData();

        $this->load->model('model_teacher');
        $data['teacherData'] = $this->model_teacher->fetchTeacherData();


        $this->load->model('model_accounting');
        $data['totalIncome'] = $this->model_accounting->totalIncome();
        $data['totalExpenses'] = $this->model_accounting->totalExpenses();
        $data['totalBudget'] = $this->model_accounting->totalBudget();
    }

    if($page == 'setting') {
        $this->load->model('model_users');
        $this->load->library('session');
        $userId = $this->session->userdata('id');
        $data['userData'] = $this->model_users->fetchUserData($userId);
    }

    if($page == 'dashboard') {
        $this->load->model('model_student');
        $this->load->model('model_teacher');
        $this->load->model('model_classes');
        $this->load->model('model_marksheet');
        $this->load->model('model_accounting');

        $data['countTotalStudent'] = $this->model_student->countTotalStudent();
        $data['countTotalTeacher'] = $this->model_teacher->countTotalTeacher();
        $data['countTotalClasses'] = $this->model_classes->countTotalClass();
        $data['countTotalMarksheet'] = $this->model_marksheet->countTotalMarksheet();

        $data['totalIncome'] = $this->model_accounting->totalIncome();
        $data['totalExpenses'] = $this->model_accounting->totalExpenses();
        $data['totalBudget'] = $this->model_accounting->totalBudget();
    }

    if($page == 'login') {
        $this->isLoggedIn();
        $this->load->view($page, $data);
    } 
    else{
        $this->isNotLoggedIn();

        $this->load->view('templates/header', $data);
        $this->load->view($page, $data);    
        $this->load->view('templates/footer', $data);    
    }
}

}

任何可以编辑此代码的人都可以提供帮助。或者，如果您认为问题不在 pages.php （上页）中，请告诉我如何解决问题。我已经提到了更多页面： -

这是 rootes.php。

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';


$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

核心文件夹

中的 MY_Controller.php

<?php 
class MY_Controller extends CI_Controller 
{
public function __construct()
{
    parent::__construct();
}

public function isLoggedIn()
{

    $this->load->library('session');

    if($this->session->userdata('logged_in') === true) {
        redirect('../dashboard');
    }
}   

public function isNotLoggedIn()

Answer 1

感谢所有人，最后我得到了正确答案，问题是由于php 7服务器中的旧版codeignitor，有关详细信息，请点击

Codeigniter session data lost after redirect

Answer 2

嗨，我面临着同样的问题。日志什么也没显示，我的Apache服务器被挂起。但就我而言，问题出在我的控制器上。我犯了一个错误。我正在日志中打印数组对象。而不是进行数组到字符串的转换。我解决了这个问题，重定向功能开始起作用。

Answer 3

只需使用刷新方法，它对我有用
