Step 1: Download / install CodeIgniter 3.

set Config Files

application/config/config.php

$config['base_url'] = 'http://localhost:8080/';
$config['sess_save_path'] = sys_get_temp_dir();

Step 3: Config codeigniter 3 Database

Simple this step to Connect Your Database using codeigniter 3

application/config/database.php

$db['default'] = array(
    'dsn'    => '',
    'hostname' => 'localhost',
    'membername' => 'root',
    'password' => '',
    'database' => 'member_mst',
    'dbdriver' => 'mysqli',
         ....
        ......
    'save_queries' => TRUE
);

Step 4: create Codeigniter 3 controller

create a codeigniter 3 controller file called Member.php

application/controllers

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
 
class Member extends CI_Controller {
 
    public function __construct() {
        parent::__construct();
        $this->load->helper(array('form', 'url'));
        $this->load->library(['form_validation','session']);
        $this->load->database();
    }
 
    public function login() {
 
        $this->form_validation->set_rules('email', 'Email', 'required');
        $this->form_validation->set_rules('password', 'Password', 'required');
 
        if ($this->form_validation->run() == FALSE) {
            $this->load->view('login_view');
        } else {
 
            $email = $this->input->post('email');
            $password = $this->input->post('password');
 
            $member = $this->db->get_where('members',['email' => $email])->row();
            
            if(!$member) {
                $this->session->set_flashdata('login_error', 'Please check your email or password and try again.', 300);
                redirect(uri_string());
            }
 
    
            if(!password_verify($password,$member->password)) {
                $this->session->set_flashdata('login_error', 'Please check your email or password and try again.', 300);
                redirect(uri_string());
            }
 
             $data = array(
                    'member_id' => $member->member_id,
                    'member_fname' => $member->member_fname,
                    'member_lname' => $member->member_lname,
                    'email' => $member->email,
                    );
 
                
            $this->session->set_memberdata($data);
 
            //simple CI_Controller 3 redirect('/'); // redirect to main auth home
            echo 'Login success!'; exit;
            
        }        
    }
 
    public function logout(){
        $this->session->sess_destroy();
        redirect('member/login');
    }
 
}

Step 5:create a login form in Codeigniter 3

login_form.php

application/views

 <div >
 
        <?php echo form_open('member/login'); ?>
 
        <div >
            <label for="email">Email address</label>
            <input type="email"  value="<?php echo set_value('email'); ?>" id="email" name="email" aria-describedby="emailHelp" placeholder="Enter Your Correct email Address">
