codeigniter-login-registration-application-structure

CodeIgniter Login Registration Script

codeigniter login and registration with session

This is where I will make a simple HTML form and PHP CodeIgniter server side source code for our web application. To make the forms simply all souce code copy and write it into your any text editor Like Notepad++, then save file it as codeigniter login system.

Step 1 – CodeIgniter Create Database and Tables

Table structure for table `member

CREATE TABLE `member` (
`member_id` int(11) NOT NULL,
`member_name` varchar(50) NOT NULL,
`member_email` varchar(50) NOT NULL,
`member_password` varchar(50) NOT NULL,
`member_age` int(11) NOT NULL,
`member_mobile` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Step 2 – Add Mysql Sample Data

Dumping data for table `member`

//CodeIgniter Login Registration Example Tutorial From Scratch
INSERT INTO `member` (`member_id`, `member_name`, `member_email`, `member_password`, `member_age`, `member_mobile`) VALUES
(1, 'Jaydeep', '[email protected]', '9898', 23, 3398256933),
(2, 'Jaydeep', '[email protected]', '9898', 23, 2142578547),
(3, 'Krunal', '[email protected]', '9898', 32, 2245875343),
(4, 'ankit', '[email protected]', '202cb962ac55656832Sddb07152d234b70', 23, 5685656585);

Step 3 – CodeIgniter Setting

Some CodeIgniter Setting for CodeIgniter Login Registration System

application>config>config.php
Remove Index.php from CodeIgniter.
application>config>autoload.php

$autoload['libraries'] = array(); 
//replace it with this code 
$autoload['libraries'] = array('session','database');

application>config>database.php
application>config>routes.php

$route['default_controller'] = 'member';

Step 4 – Member Controller

application>>controller >> named Member.php

<?php
 
class Member extends CI_Controller {
 
public function __construct(){
 
        parent::__construct();
  	$this->load->helper('url');
  	$this->load->model('member_model');
        $this->load->library('session');
 
}
}
?>

4.2 –> codeigniter Create a new Index method for Member Controller

public function index()
{
$this->load->view("signup.php");
}

4.3 –> codeigniter signup_member()

public function signup_member(){

      $member=array(
      'member_name'=>$this->input->post('member_name'),
      'member_email'=>$this->input->post('member_email'),
      'member_password'=>md5($this->input->post('member_password')),
      'member_age'=>$this->input->post('member_age'),
      'member_mobile'=>$this->input->post('member_mobile')
        );
        print_r($member);

$email_check=$this->member_model->email_check($member['member_email']);

if($email_check){
  $this->member_model->signup_member($member);
  $this->session->set_flashdata('preview_success_msg', 'SignUped successfully.Now login to your account.');
  redirect('member/signin_view');

}
else{

  $this->session->set_flashdata('preview_err_msg', 'Error occured,Try again.');
  redirect('member');


}

}

4.4 –> simple signin_view()

public function signin_view(){
 
$this->load->view("login.php");
 
}

4.5 –> codeigniter login_member()

function login_member(){
  $member_login=array(
 
  'member_email'=>$this->input->post('member_email'),
  'member_password'=>md5($this->input->post('member_password'))
 
    );
 
    $data=$this->member_model->login_member($member_login['member_email'],$member_login['member_password']);
      if($data)
      {
        $this->session->set_memberdata('member_id',$data['member_id']);
        $this->session->set_memberdata('member_email',$data['member_email']);
        $this->session->set_memberdata('member_name',$data['member_name']);
        $this->session->set_memberdata('member_age',$data['member_age']);
        $this->session->set_memberdata('member_mobile',$data['member_mobile']);
 
        $this->load->view('member_profile.php');
 
      }
      else{
        $this->session->set_flashdata('preview_err_msg', 'Error occured,Try again.');
        $this->load->view("login.php");
 
      }
 
 
}

4.6 –> CodeIgniter member_profile()

function member_profile(){
 
$this->load->view('member_profile.php');
 
}

4.7 –> codeigniter member_logout()

public function member_logout(){
 
  $this->session->sess_destroy();
  redirect('member/signin_view', 'refresh');
}

4.8 –> codeigniter Member Controller

<?php
 
class Member extends CI_Controller {
 
public function __construct(){
 
        parent::__construct();
  			$this->load->helper('url');
  	 		$this->load->model('member_model');
        $this->load->library('session');
 
}
 
public function index()
{
$this->load->view("signup.php");
}
 
public function signup_member(){
 
      $member=array(
      'member_name'=>$this->input->post('member_name'),
      'member_email'=>$this->input->post('member_email'),
      'member_password'=>md5($this->input->post('member_password')),
      'member_age'=>$this->input->post('member_age'),
      'member_mobile'=>$this->input->post('member_mobile')
        );
        print_r($member);
 
$email_check=$this->member_model->email_check($member['member_email']);
 
if($email_check){
  $this->member_model->signup_member($member);
  $this->session->set_flashdata('preview_success_msg', 'SignUped successfully.Now login to your account.');
  redirect('member/signin_view');
 
}
else{
 
  $this->session->set_flashdata('preview_err_msg', 'Error occured,Try again.');
  redirect('member');
 
 
}
 
}
 
public function signin_view(){
 
$this->load->view("login.php");
 
}
 
function login_member(){
  $member_login=array(
 
  'member_email'=>$this->input->post('member_email'),
  'member_password'=>md5($this->input->post('member_password'))
 
    );
 
    $data=$this->member_model->login_member($member_login['member_email'],$member_login['member_password']);
      if($data)
      {
        $this->session->set_memberdata('member_id',$data['member_id']);
        $this->session->set_memberdata('member_email',$data['member_email']);
        $this->session->set_memberdata('member_name',$data['member_name']);
        $this->session->set_memberdata('member_age',$data['member_age']);
        $this->session->set_memberdata('member_mobile',$data['member_mobile']);
 
        $this->load->view('member_profile.php');
 
      }
      else{
        $this->session->set_flashdata('preview_err_msg', 'Error occured,Try again.');
        $this->load->view("login.php");
 
      }
 
 
}
 
function member_profile(){
 
$this->load->view('member_profile.php');
 
}
public function member_logout(){
 
  $this->session->sess_destroy();
  redirect('member/signin_view', 'refresh');
}
 
}
 
?>

Step 5 – Create CodeIgniter Member Model

5.1 -> application>>model folder >> Member_model.php

<?php
class Member_model extends CI_model{
}
?>

5.2 –> codeigniter signup_member()

public function signup_member($member){
$this->db->insert('member', $member);

}

5.3 –> codeigniter login_member()

public function login_member($email,$pass){
 
  $this->db->select('*');
  $this->db->from('member');
  $this->db->where('member_email',$email);
  $this->db->where('member_password',$pass);
 
  if($query=$this->db->get())
  {
      return $query->row_array();
  }
  else{
    return false;
  }
 
 
}

5.4 -> codeigniter email_check Functions

public function email_check($email){
 
  $this->db->select('*');
  $this->db->from('member');
  $this->db->where('member_email',$email);
  $query=$this->db->get();
 
  if($query->num_rows()>0){
    return false;
  }else{
    return true;
  }
 
}

5.5 -> Member_Model Source code

<?php
class Member_model extends CI_model{
 
public function signup_member($member){
 
$this->db->insert('member', $member);
 
}
 
public function login_member($email,$pass){
 
  $this->db->select('*');
  $this->db->from('member');
  $this->db->where('member_email',$email);
  $this->db->where('member_password',$pass);
 
  if($query=$this->db->get())
  {
      return $query->row_array();
  }
  else{
    return false;
  }
 
 
}
public function email_check($email){
 
  $this->db->select('*');
  $this->db->from('member');
  $this->db->where('member_email',$email);
  $query=$this->db->get();
 
  if($query->num_rows()>0){
    return false;
  }else{
    return true;
  }
 
}
 
 
}
 
 
?>

Step 6- Make A SignUp Form (HTML View)

Create a simple SignUp.php File

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>SignUp -CodeIgniter SignIn Registration</title>

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" media="screen" title="no title">


  </head>
  <body>

<span style="background-color:red;">
  <div class="container">
      <div class="row">
          <div class="col-md-4 col-md-offset-4">
              <div class="login-panel panel panel-success">

                  <div class="panel-body">

                  <?php
                  $preview_err_msg=$this->session->flashdata('preview_err_msg');
                  if($preview_err_msg){
                    echo $preview_err_msg;
                  }
                   ?>

                      <form role="form" method="post" action="<?php echo base_url('member/signup_member'); ?>">
                          <fieldset>
