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);
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');
}
