Tutorial Contents

okay, on this occasion I will share a tutorial how to make different access for multiple user on a website, which makes different access for each user , we will create a user level table in the database. we just start step by step:

DATABASE

first create a database with a name sidmm

then create a user table by name user

as in the picture above we create a table name and number of table fields

in the user table there is a field username, password, and level to give different access when the password is successful.

after that we will create a form to log in.

FORM VIEWS, CONTROLLER, AND MODELS

then open your text editor, here I use visual studio code, you can use what you like, maybe SBLIME or another text editor.
create a file with the name welcome.php in the view folder

<div class="card-body">
                <br><br>
                <div class="row">
                    <div class="col-md-1"></div>
                    <div class="col-md-10">
                        <div class="row">
                            <div class="col-md-4 mb-3">
                                 <a href="plogin" type="button" class="btn btn btn-danger btn-lg btn-block"><h3 class='fas fa-user-cog'></h3> pengawas</a>
                            </div>
                            <div class="col-md-4 mb-3">
                            <a href="login"type="button" class="btn btn-primary btn-lg btn-block"><h3 class='fas fa-user-edit'></h3> perangkat</a>
                            </div>
                            <div class="col-md-4 mb-3">
                            <a href="Opsidesa" type="button" class="btn btn-success btn-lg btn-block"><h3 class='fas fa-users'></h3>masyarakat</a></div>
                        </div>
                    </div>
                    <div class="col-md-1"></div>
                </div>
                <br><br>
            </div>

full code on my github

Create a form with three options, I use this button for three types of logins.
the results are as below:

then create a form for the input username and password in the view folder with the name login.php

<form action="" method="post">   
                                    <div class="form-group">
                                    <label for="email">Username:</label>
                                    <input type="text" class="form-control" id="email" placeholder="Enter email" name="username">
                                    </div>
                                    <div class="form-group">
                                    <label for="pwd">Password:</label>
                                    <input type="password" class="form-control" id="pwd" placeholder="Enter password" name="password">
                                    </div>
                                    <div class="form-group form-check">
                                    <label class="form-check-label">
                                        <input class="form-check-input" type="checkbox" name="remember"> Remember me
                                    </label>
                                    </div>
                                    <button type="submit" class="btn btn-primary">Masuk</button>
                                </form>
                                </div>

this is part of the login page redirect action <form action="<?php echo base_url('login/aksi_login'); ?>" method="post">

full code

the form as shown below:

then create a file for the login model named M_Login.php in the models folder

<?php
class M_login extends CI_Model{

    function cek_login($data){
        $this->db->get_where('user',$data);
        return $this->db->affected_rows();
    }
}

this is the section for selecting database tables $this->db->get_where('user',$data);
this is to give effect to the database row return $this->db->affected_rows();

then we will create a controller file with the name Login.php in the controller folder

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Login extends CI_Controller{
function __construct(){
    parent::__construct();      
    $this->load->model('M_login');
}
function index(){
    $this->load->view('login');
}
function aksi_login(){
    $username = $this->input->post('username');
    $password = $this->input->post('password');

    $where = array(
        'username' => $username,
        'password' => $password,
        'level'=>'1'
        );
    $cek = $this->M_login->cek_login($where);   
    if($cek > 0){
        $data_session = array(
            'nama' => $username,
            'status' => "login"
            );
        $this->session->set_userdata($data_session);
        redirect(base_url().'dashboard', $data_session);
    }else{
        echo "Username and password wrong !";
    }
}
function logout(){
    $this->session->sess_destroy();
    redirect(base_url('Login'));
 }
}

I will give a little explanation for the code above:
this is fuction to load the model files $this->load->model('M_login'); in the models folder
and this $this->load->view('login'); to load login page on view folder.
then this function aksi_login(){ $username = $this->input->post('username'); $password = $this->input->post('password'); is a function for login actions that will check username and password
and this is the main part which is to determine user access.

$where = array(
        'username' => $username,
        'password' => $password,
        'level'=>'1'
        );

this form will only work if the username and password entered have level=1
and this $this->session->set_userdata($data_session); redirect(base_url().'dashboard', $data_session); serves to create a login session for users who have successfully logged in.
the last is for the logout functionfunction logout(){ $this->session->sess_destroy(); redirect(base_url('Login')); This function to delete data sessions that were previously created if the user logout and will be returned on the login page.

full code for:controllers/Login.php

then the next thing you have to make is the model file and controllers file for the next access, the same way, what you have to distinguish is the number of levels.
If we already, let's run it.

RUNNING PROGRAM

first step run page welcome.php in your browser.

it will appear as below

then select the admin button, then enter a username and password that has level = 1 we can see the user table that we have entered some data.

then click login button

alt

then we see the difference
if we login to the admin button and use the user with level = 1 then we will be directed to the admin page.
