How to create Login Logout functionality with session ?

How to create Login Logout functionality with session ?

In Few Basic Steps we can create Login-Logout with session




Step 1 :   
   
    Load Libraries in autoload.php        //Location :    application/config/autoload.php


    $autoload['libraries'] = array('database', 'email', 'session');

   



Step 2 :   
   
    Load Drivers in autoload.php        //Location :    application/config/autoload.php
   
    $autoload['drivers'] = array('session');


  
   
Step 3 :   
   
    Load Helper Libraries in autoload.php        //Location :    application/config/autoload.php
   
    $autoload['helper'] = array('url', 'file');


Now Comes Logical part We will create Two Controller files & Two View Files One for Before Login & Another for After Login Functionalities

Our Two controller will "Account" and "User" and views will "login_view" and "dashboard_view"




Step 4 :   

    First Create view using simple form on login_view page
   
    Form Code:
   
    <form method="post" action="<?php echo site_url('account/login');?>">
        <table>
            <tr>
                <td><input type="text" name="email" value="" placeholder="E-mail"/></td>
            </tr>
            <tr>
                <td><input type="password" name="password" value="" placeholder="*****" /></td>
            </tr>
            <tr>
                <td><input type="submit" name="login" value="Login" /></td>
            </tr>
        </table>
    </form>




Step 5 :   
   
    Add login logic on Account Controller Page We will use simple & static you can use dynamic using database
   
    function login()
    {
        $email=$this->input->post('email');
        $password=$this->input->post('password');
        if($email=='test@gmail.com' && $password=='123456')
        {
            $session_data=array(
                                'id'=>1,
                                'email'=>$email,
                                'islogin'=>True,
                            );
//            $this->session->set_data($session_data);  //if this line show error use
            $this->session->set_userdata($session_data);

            redirect('user');
        }
    }


   
Step 6:

    On User Controller create the constructor function so that it will called before calling any function
   
   public function __contruct()
    {
        parent::__contruct();
        if((!$this->session->has_userdata('id'))||(!$this->session->has_userdata('email'))||(!$this->session->has_userdata('islogin')))
        {
            redirect('account/login');
        }
    }






Step 7:

    Create a function on User controller to show welcome page simply load welcome page
   
    function dashboard()
    {
        $this->load->view('dashboard');
    }


 
Step 8:
   
    Create dashboard view to show welcome message and user email id
   
    <a href="<?php echo site_url('account/logout');?>">Logout</a>
   
    <h3>Hello <?php echo $this->session->userdata('email');?><h3>
    

Step 9:

    Create Logout functionality on Account controller page
   
    function logout()
    {
        $this->session->sess_destroy();
        redirect('account/login');
    }
