Codeigniter

Ci Working step wise

===========================================
site_url/index.php/controller/controller_function

Front End section displying of Website
=========================================================
Step 1- Create assests folder and put inside all css,js,images,fonts, pdf..etc

Step 2- Go to Application->views (create two folders admin & web) and also in under admin& web create 2 folders pages and templates

Step 3- in under templates put all the head, header, footer, sidebar, .......etc....

Step 4- in under pages put all about us, our team, courses, contact us......etc....

Step 5- How to set base url Go to Application->config->config.php and put this $config['base_url'] = 'http://localhost/ci/ci_hometopper/';

Step 6- How to create database connection Go to Application->config->database.php and put here db name, user name and password.

Step 7- Go to Application->config->routes.php here set controller name by default set 'welcome'

Step 8- Go to Application->controllers create 2 folders admin(in this under create Admin.php controller(Ist letter capital letter) ) and front(in this under create

Front.php controller((Ist letter capital letter) )

Step 9- Go to Application->models create 2 folders admin(in this under create Admin.php controller(ist letter capital letter) ) and web(in this under create Front.php

controller(Ist letter capital letter) )

Step 10- Go to Application->controllers-> create controller Front.php and under this file write:- class Front extends CI_Controller { (Where Front is controller name) {

ex- Front.php
====================================================================
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Front extends CI_Controller {  (Where front is controller name)

function __construct()
  {
       parent::__construct();
      // $this->load->model('Admin_modal');
  // $this->load->model('web/front_modal');
       $this->load->helper('url');
   $this->load->library('session');
   }


public function index()
{
$this->load->view('welcome_message');
                $this->load->view('web/templetes/header_home');
}
}
===================================================================

and inner this call constructor function

function __construct()
  {
       parent::__construct();
      // $this->load->model('Admin_modal');
  // $this->load->model('web/front_modal');
       $this->load->helper('url');
   $this->load->library('session');
   }

and load all pages as-

public function index()
{
//$this->load->view('welcome_message');
$this->load->view('web/templetes/header_home');
$this->load->view('web/templetes/menu');
$this->load->view('web/templetes/quick_contact');
$this->load->view('web/pages/index');
$this->load->view('web/templetes/footer');
}


public function about()
{
//$this->load->view('welcome_message');
$this->load->view('web/templetes/header_home');
$this->load->view('web/templetes/menu');
$this->load->view('web/templetes/quick_contact');
$this->load->view('web/pages/about');
$this->load->view('web/templetes/footer');
}


Step 11- add this code all pages including header, footer

<?php
$base_url=base_url().'assests/';
$uri= $this->uri->segment(1);
 ?>

call style <link rel="stylesheet" href="<?php echo $base_url;?>css/custom.css">

call js <script src="<?php echo $base_url;?>js/scrollTop.js"></script>

call images <img src="<?php echo $base_url;?>images/htlogo.jpg" alt="organic logo">

Step 12- Go to Application->config> routes.php->load default controller $route['default_controller'] = 'Front'; and set all pages links $route['index'] = "Front/index";
 $route['about-us'] = "Front/about";
(where about-us page name and about controller name)

Step 13-Remove index.php from url

=>site_url/index.php/controller/controller_function
-but we want Remove index.php from url
create HT(.htaccess) ACCESS file in root directory and remove index.php from main url

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

</IfModule>

==========================================
Admin Section (Back End section)  displying of Website
=========================================================

Step 14- add admin panel create root folder name-> admin-assets (put here -> css, js, images, fonts)

Step 15- and put pages application->views->admin->pages-> (put all admin pages ex- login.php,index.php....etc)

Step 16- put admin pages top <?php
$base_url=base_url().'admin-assests/';
$uri= $this->uri->segment(1);
 ?>

<link href="<?php echo $base_url;?>css/bootstrap.min.css" rel="stylesheet">

Step 17- create Admin section on
/////////////////////////admin section////////////////////

$route['admin'] = "Admin/index";

//Where->admin-> url name any http://localhost/ci/childsurgeon/admin(if lalit- http://localhost/ci/childsurgeon/lalit)
         //Admin->Controller Name
//index->Function Name under admin controller

$route['admin/login'] = "Admin/login";

$route['admin/home'] = "Admin/home";

Step 18- Admin controller -

class Admin extends CI_Controller {

function __construct()
  {
       parent::__construct();
      // $this->load->model('Admin_modal');
  // $this->load->model('web/front_modal');
       $this->load->helper('url');
   $this->load->library('session');
    $this->load->database();
   }

public function index()
{
//$this->load->view('web/templates/header');
$this->load->view('admin/pages/index');
}

public function login()
{
//$this->load->view('web/templates/header');
//$this->load->view('admin/pages/login');
echo $user_name= $this->input->post('user_admin');
echo  $password= $this->input->post('password_admin');

$this->db->select('*');
$this->db->from('users');
$this->db->where("user_name='$user_name' and user_password='$password'");
$query=$this->db->get();
//print_r($query);
$result=$query->num_rows();

if ($result==1) {
redirect("admin/home");
}

}

public function home()
{
//$this->load->view('web/templates/header');
$this->load->view('admin/pages/home');
}

How To Set Files In Codeignitor
====================================
step 1 - Create Folder assets(under codeignitor & same level application) in here all js, css, images, fonts, plugins (all folder) paste

step 2 - Go application -> config (set base url ex- $config['base_url'] = 'http://localhost/CodeIgniter/kgac/';)
         and set encryption key ex - $config['encryption_key'] = 'fasdfasdf';

step 3 - Go application -> database (set database detail ex - )

        'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'ca',

step 4 - Go application -> routes (set controller name ex - $route['default_controller'] = 'home'; Where contoller name = home)

step 5 - Go application -> views (set here all pages ex- header.php, footer.php, sidebar.php, aboutus.php & ect..)

step 6 - Go application -> controller (set own controller ex - (conroller name) home, front, my_controller ect. as you want)

<?php
class home extends CI_Controller {


function __construct()
       {
               parent::__construct();
  $this->load->helper(array('form', 'url'));

}

public function index()
{
$this->load->view('home');
}
}

Where contoller name -> home

step 7 - Go application -> models (set own models ex - (models name) admin, front, my_model ect. as you want)
