Step 1

  •  Download Codeigniter latest version.

1. autoload.php -replace $autoload[‘libraries’]=”;$autoload[‘helper’]=”; with following

$autoload['libraries'] = array('database');
$autoload['helper'] = array('url', 'file');

2. Edit datapase.php : according to your database configuration like username,password,database

3. Edit config.php  -$config[‘base_url’] = ”;

$config['base_url'] = 'http://localhost/cidemo/';

4.Edit Route.php  -$route[‘default_controller’] = ‘welcome’;

$route['default_controller'] = 'demo/menu';

Step 2

1  Create controller file  Demo.php in controller folder

 

<?php
defined('BASEPATH') or exit('No direct script access allowed');
//require APPPATH . ' / libraries / BaseController.php';
class Demo extends CI_Controller
{

    /**
     * Index Page for this controller.
     *
     * Maps to the following URL
     *         http://example.com/index.php/welcome
     *    - or -
     *         http://example.com/index.php/welcome/index
     *    - or -
     * Since this controller is set as the default controller in
     * config/routes.php, it's displayed at http://example.com/
     *
     * So any other public methods not prefixed with an underscore will
     * map to /index.php/welcome/<method_name>
     * @see https://codeigniter.com/user_guide/general/urls.html
     */
    public function __construct()
    {
        parent::__construct();
        $this->load->model('g_model');
        $this->load->helper('string');
        ini_set('max_execution_time', 44540);
        ini_set('memory_limit', '2048M');
       
    }
    
    public function menu(){
        $data['lst']= $this->g_model->CategoryList(1);
         $this->load->view('menu',$data);
     }
    
////////////////////////////////////////////////////////////////////////////////////////
}

2.Create model g_model.php in model folder

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

class G_model extends CI_Model
{
    function hasChild($parent_id)
    {
      $sql = $this->db->query("SELECT COUNT(*) as count FROM tbl_category WHERE parent_id = '" . $parent_id . "'")->row();
      return $sql->count;
    }
function CategoryList($id)
  {
    $list = "";
    $sql = "SELECT * FROM tbl_category  WHERE parent_id=0 ";
    $qry = $this->db->query($sql);
    $parent =  $qry->result();
    //print_r($parent);
    $mainlist = "<ul>";
    foreach($parent as $pr){
         $mainlist .= $this->CategoryTree($list,$pr->id,$pr->cat_name,$append = 0);
    
    }
    $list .= "</li></ul>";
    return $mainlist;
  }
  function CategoryTree($list,$id,$name,$append)
  {
    $list = '<li><a href="#">'.$name.'</a>';
    
    if ($this->hasChild($id)) // check if the id has a child
    {
      $append++;
      $list .= "<ul>";
      $sql = "SELECT * FROM tbl_category WHERE parent_id =$id";
      $qry = $this->db->query($sql);;
      $child = $qry->result();
      foreach($child as $pr){
        $list .= $this->CategoryTree($list,$pr->id,$pr->cat_name,$append);
      };
      $list .= "</ul>";
    }
    return $list;
  }
}

<IfModule mod_rewrite.c>
 RewriteEngine On

 #If you are having problems with the rewrite rules, remove the "#" from the
 #line that begins "RewriteBase" below. You will also have to change the path
 #of the rewrite to reflect the path to your base path.
 #RewriteBase /
    
	RewriteRule  ^/?ajax/(.*)$ ajax.php?$1 [NC,QSA,L]
	
	SetEnv MAGIC_QUOTES 0
	SetEnv PHP_VER 5
	Options +FollowSymlinks -MultiViews
	RewriteEngine On
	DirectoryIndex index.php
	RewriteCond %{REQUEST_URI} ^system.*
	RewriteRule (.*) index.php?/$1 [L]
	RewriteCond %{REQUEST_FILENAME} !-f
	RewriteCond %{REQUEST_FILENAME} !-d
	RewriteCond $1 !^(index\.php|images|robots\.txt|css)
	RewriteRule (.*) index.php?/$1 [L]
 
</IfModule>
<IfModule mod_headers.c>
Header add Cache-Control:  "no-store, no-cache, must-revalidate"
