I'm just new using codeIgniter and I wanted to create a simple login with sign up and session.
Here's my code...
<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
class LoginVerify extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('userModel', '', TRUE);
}
function index() {
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required');
$this->form_validation->set_rules('password', 'Password', 'trim|required|callback_this_database');
if($this->form_validation->run()==FALSE) {
$this->load->view('login_view');
}
else {
redirect('home', 'refresh');
}
}
function this_database($password) {
$username=$this->input->post('username');
$result=$this->user->login($username, $password);
if($result) {
$sess_array=array();
foreach($result as $row) {
$sess_array=array('id'=>$row->id, 'username'=>$row->username);
$this->session->set_userdata(logged_in, $sess_array);
}
return TRUE;
}
else {
$this->form_validation->set_message(this_database, 'Invalid username or password');
return FALSE;
}
}
}
?>
I don't know why I'm still receiving error when trying to run this program.
i think because of this
else {
redirect('home', 'refresh');
//means you are going to controller named home, but your controller name is LoginVerify
}
guess it will solve your problem
You are calling db queries on callback try your method part in after validation success also create a alias for usermodel. also check you have already included session library.
Also you left syntax errors so try my full code:-
<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
class LoginVerify extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('userModel', 'user');
}
function index() {
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required');
$this->form_validation->set_rules('password', 'Password', 'trim|required');
if($this->form_validation->run()==FALSE) {
$this->load->view('login_view');
}
else {
$username=$this->input->post('username');
$password=$this->input->post('password');
$result=$this->user->login($username, $password);
if($result) {
$sess_array=array();
foreach($result as $row) {
$sess_array=array('id'=>$row->id, 'username'=>$row->username);
$this->session->set_userdata('logged_in', $sess_array);
}
redirect('home', 'refresh');
}
else {
$this->form_validation->set_message('this_database', 'Invalid username or password');
redirect('home', 'refresh');
}
}
}
}
?>
$this->form_validation->set_rules('username', 'Username', 'trim|required');
$this->form_validation->set_rules('password', 'Password', 'trim|required');
try to change
$this->load->model('userModel', '', TRUE);
to
$this->load->model('userModel', 'user');
and better remove php close tag at the end of the script

When I load the main page and try to leave the login details blank,I get page you requested is not found.This my code main and login files resp. kindly help
<?php

{
$this->login();
}
public function login()
{
$this->load->view('login');

if($this->form_validation->run())
{
redirect('main/members');

This means your login.php view does not exist.
You should check your view folder to see if login.php exist there.

Using raw php, you check session data using $_SESSION
Inside codeigniter, you can check session data using print_r($this->session->all_userdata());
Codeigniter follows the MVC design model this means that data is first generated by a module is passed then to a controller and finally the controller inflates data into a certain view.
Load a view from Controller
$this->load->view('view_name', $data, true/false);
in this example you see how to load a view passing to it some data.
So assuming you have a view in your view folder called show_session.php
we can create the following method in the controller to show the session data you want the user to be able to see.
public function index()
{
$data['info'] = $this->session->all_userdata();
$this->load->view('show_session',$data);
}
Create the view
In case you don't have that view you create it with the following contents:
<!DOCTYPE html>
<html>
<head>
<title>Simple data</title>
</head>
<body>
<?php
foreach ($info as $key => $value) {
echo $key." => ".$value."<br>";
}
?>
</body>
</html>
finally save it into /application/views folder.

I want to connect from one controller in one module to another controller in another module. I want to go from my login module to my dashboard module and use a function inside the dashboard module. Just basically switch from my login module to my dashboard module. Here is my login controllers and my dashboard controller.
class Login extends MX_Controller {
function index()
{
$this->load->view('includes/header');
$this->load->view('login_form');
$this->load->view('includes/footer');
}
function validate_credentials()
{
$this->load->model('membership_model');
$query = $this->membership_model->validate();
if($query) // if the user's credentials validated...
{
$data = array(
'username' => $this->input->post('username'),
'is_logged_in' => true
);
$this->session->set_userdata($data);
redirect('login/site/members_area');
}
else // incorrect username or password
{
$this->index();
}
}
function signup()
{
//$data['main_content'] = 'signup_form';
//$this->load->view('includes/template', $data);
$this->load->view('includes/header');
$this->load->view('signup_form');
$this->load->view('includes/footer');
}
function create_member()
{
$this->load->library('form_validation');
// field name, error message, validation rules
$this->form_validation->set_rules('first_name', 'Name', 'trim|required');
$this->form_validation->set_rules('last_name', 'Last Name', 'trim|required');
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|callback_check_if_email_exists');
$this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[4]|max_length[15]|callback_check_if_username_exists');
$this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
$this->form_validation->set_rules('password2', 'Password Confirmation', 'trim|required|matches[password]');
if($this->form_validation->run() == FALSE) // didn't validate
{
$this->load->view('includes/header');
$this->load->view('signup_form');
$this->load->view('includes/footer');
}
else
{
$this->load->model('membership_model');
if($query = $this->membership_model->create_member())
{
$data['account created'] = 'Your account has been created. <br /> <br /> You may now login';

my second login controller
class Site extends MX_Controller {
public function __construct()
{
parent::__construct();
$this->is_logged_in();
$this->lang->load('login/login/', 'english');
}
function members_area()
{
$this->load->view('logged_in_area');
//$this->load->module('dashboard/dashboard');
//$this->load->view('home');
}
function is_logged_in()
{
$is_logged_in = $this->session->userdata('is_logged_in');
if(!isset($is_logged_in) || $is_logged_in != true)
{
echo 'You don\'t have permission to access this page. Login';
die();
//$this->load->view('login_form');
}
}
}
the controller in my dashboard module has a function called home I am trying to connect to and use. And the home function of the dashboard has a connection to another module but I cannot get the connection from login to dashboard to work. Also the way my login works I need to connect to the dashboard module through my members_area function. All help greatly appreciated.
Assuming you're using this library
From controller you can use Modules::load or $this->load-module
$moduleInstance = $this->load->module('yourmodule');
// or
$moduleInstance = Modules::load('yourmodule');
// Now you can call any public module controller method
$moduleInstance->somePublicMethod($arg1, $argn);
// you can also use $this->yourmodule as a model instance
Hope this helps
I have codeigniter installed on my localhost
The main.php controller is
class Main extends CI_Controller {
public function index()
{
$this -> login();
}
public function login()
{
$this->load->view('login');
}
public function login_validation() {
$this->load->library('form_validation');
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required|md5');
if($this->form_validation->run())
{
redirect('main/members');
}
else
{
$this->load->view('login');
}
}
}
The login is working page is coming,but after I fill the username and password,should take me to login/main/login_validation and from there the function login_validation() should either redirect to main/members or show me the login page.But what happens is when I submit the form,the object not found error is coming.Can anyone help me out?
form is
form_open('main/login_validation');
To answer what I think your question is getting at, you're using the form_validation class wrong. You should be testing whether or not the form_validation->run() is TRUE (all fields passed validation) or FALSE (there was an error in one or more of the inputs). Structure you code like such:
public function login_validation() {
$this->load->library('form_validation');
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required|md5');
if ($this->form_validation->run() === FALSE)
{
$this->load->view('login');
}
else
{
redirect('main/members');
}
}
This is covered in the CodeIgniter documentation here.
in your controller ..you could try this..
function index()
{
//This method will have the credentials validation
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
if($this->form_validation->run() == FALSE)
{
//Field validation failed. User redirected to login page
$this->load->view('login');
}
else
{
$this->check_database();
//redirect('home');
}
}
function check_database()
{
//Field validation succeeded. Validate against database
$username = $this->input->post('username');
$password = $this->input->post('password');
//query the database
$query_result = $this->model_login->login($username, $password);
if($query_result)
{
$this->load->view('main/members');
}
else
{
redirect('login');
}
}
in model
function login($username,$password){
$query = $this->db->query("SELECT * FROM `login` WHERE `username`= '".$username."' AND
password='".$password."' LIMIT 1");
if ($query->num_rows() > 0)
return TRUE;
else
return FALSE;
}
i made a controller name of user.php i test complete project on local host it works fine but when i upload online on website it shows error , i submit the form then form load controller called user.php and error on the first line its called parse error i check but still the same will you please suggest.
<?php
class User extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
}
public function create_user()
{
// field name, error message, validation rules
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
$this->form_validation->set_rules('city', 'City', 'trim|required');
if($this->form_validation->run() == FALSE)
{
$this->load->view('ar_signup');
}
else
{
$this->load->model('Users_model');
if($this->input->post("language")=="ar")
{
$this->load->view('ar_thanks');
}
else
{
$this->load->view('en_thanks');
}
if($query = $this->Users_model->create_member())
{
$this->load->view('ar_thanks');
}
}
}
}
Please format your code and use IDE. And you will not have these errors. Your formatted code:
<?php
class User extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
}
public function create_user()
{
// field name, error message, validation rules
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
$this->form_validation->set_rules('city', 'City', 'trim|required');
if($this->form_validation->run() == FALSE) {
$this->load->view('ar_signup');
} else {
$this->load->model('Users_model');
if($this->input->post("language")=="ar") {
$this->load->view('ar_thanks');
} else {
$this->load->view('en_thanks');
}
if($query = $this->Users_model->create_member()) {
$this->load->view('ar_thanks');
}
}
}
