php - 如何从codeigniter中应用程序文件夹之外的另一个页面重定向到管理/登录页面

问题描述

我在 codeigniter 的应用程序文件夹之外创建了一些文件。以下是我的文件夹和文件的结构在此处输入图像描述

sys_config.php是默认文件，如果满足条件，它将重定向到应用程序文件夹下的b0a.php或 admin/login 。

sys_config.php 代码

 $sql ="SELECT host FROM tray WHERE host = '$host'";

       $ret = mysqli_query($mysqli,$sql);
       $row = mysqli_fetch_array($ret);

      if ($row['host'] != '' && $row['host'] == $host) {

        redirect("index", true);
    } else {
        //echo "<p>Nothing matched your query.</p>";
        redirect("b02.php", true);

    }

在控制器下的 install.php 中，我有这个

<?php

Class Install extends CI_Controller {

    function __construct()
    {
        parent::__construct();

        //load in some helpers
        $this->load->helper(array('form', 'file', 'url','language'));

        if($this->session->userdata('lang')!="")
        {
            $this->lang->load('admin',$this->session->userdata('lang'));
        }else{
            $this->lang->load('admin', 'english');
        }

        //if this system is already installed redirect to the homepage
        if(file_exists(FCPATH.'application/config/setup.php'))
        {
            //redirect('admin/login');
            redirect('sys_config');
        }

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

    function index()
    {
        //build our checks
        $data = array();
        //Destroy All Session
        $this->session->sess_destroy();
        //check for writable folders
        $data['is_writeable']['root'] = is_writeable(FCPATH);
        $data['is_writeable']['config'] = is_writeable(FCPATH.'application/config/');
        $data['is_writeable']['uploads'] = is_writeable(FCPATH.'uploads/');

        $this->form_validation->set_rules('hostname', 'Hostname', 'required');
        $this->form_validation->set_rules('database', 'Database Name', 'required');
        $this->form_validation->set_rules('username', 'Username', 'required');
        $this->form_validation->set_rules('password', 'Password', 'trim');
        $this->form_validation->set_rules('prefix', 'Database Prefix', 'trim');

        $this->form_validation->set_rules('ssl_support');
        $this->form_validation->set_rules('mod_rewrite');

        if ($this->form_validation->run() == FALSE)
        {
            $data['errors'] = validation_errors();
            $this->load->view('install', $data);
        }
        else
        {
            // Unset any existing DB information
            unset($this->db);

            //generate a dsn string
            $dsn = 'mysqli://'.$this->input->post('username').':'.$this->input->post('password').'@'.$this->input->post('hostname').'/'.$this->input->post('database');

            //connect!
            $this->load->database($dsn);

            if (is_resource($this->db->conn_id) OR is_object($this->db->conn_id))
            {
                //setup the database config file
                $settings                   = array();
                $settings['hostname']       = $this->input->post('hostname');
                $settings['username']       = $this->input->post('username');
                $settings['password']       = $this->input->post('password');
                $settings['database']       = $this->input->post('database');
                $settings['prefix']         = $this->input->post('prefix');             
                $file_contents              = $this->load->view('templates/database', $settings, true);
                write_file(FCPATH.'application/config/database.php', $file_contents);
                $setup_file = "//This Is Setup File";
                write_file(FCPATH.'application/config/setup.php',$setup_file);
                //setup the CodeIgniter default config file

                $config_index               = array('index'=>'index.php');
                if($this->input->post('mod_rewrite'))
                {
                    $config_index           = array('index'=>'');
                }
                $file_contents              = $this->load->view('templates/config', $config_index, true);
                write_file(FCPATH.'application/config/config.php', $file_contents);



                //setup the .htaccess file
                if($this->input->post('mod_rewrite'))
                {
                    $subfolder = trim(str_replace($_SERVER['DOCUMENT_ROOT'], '', FCPATH), '/').'/';
                    $file_contents              = $this->load->view('templates/htaccess', array('subfolder'=>$subfolder), true);
                    write_file(FCPATH.'.htaccess', $file_contents);
                }
                $this->load->library('migration');

                if ( ! $this->migration->current())
                {
                    show_error($this->migration->error_string());
                }

                //redirect to the admin login
                redirect('register');
            }
            else
            {
                $data['errors'] = '<p>A connection to the database could not be established.</p>';
                $this->load->view('install', $data);
            }
        }
    }

}

我使用以下命令重定向到应用程序文件夹之外的 sys_config：

//if this system is already installed redirect to the homepage
        if(file_exists(FCPATH.'application/config/setup.php'))
        {
            //redirect('admin/login');
            redirect('sys_config');
        }

一切正常。但现在我尝试重定向回 admin/login 这给了我：

请问，如何从sys_config.php重定向到 admin/login？

标签： phpcodeigniter-3

解决方案

您应该admin/login从重定向检查中排除 url .. 因为这里发生的是它被重定向到admin/login我相信它有一个登录检查然后重定向方法如果未登录则不满足因此它被重定向到推荐人和很快 ..

在你检查添加如果 uri 段字符串等于admin/login然后不要重定向。
