passing user information to view in codeigniter - php

Question

I am trying to get users details from the database and put it in session so that it can be used in the view. I have tried all I can but I keep getting error. Undefined Variable Email.
MODEL:
function login($username, $password)
{
$this->db->select('authTbl.id, authTbl.password, authTbl.username, authTbl.email, authTbl.mobile');
$this->db->from('users as authTbl');
$this->db->where('authTbl.username', $username);
$this->db->where('authTbl.isDeleted', 0);
$query = $this->db->get();
$user = $query->result();
if(!empty($user)){
if(verifyHashedPassword($password, $user[0]->password)){
return $user;
} else {
return array();
}
} else {
return array();
}
}
CONTROLLER:
function isLoggedIn()
{
$isLoggedIn = $this->session->userdata('isLoggedIn');
$data['title'] = 'Login';
if(!isset($isLoggedIn) || $isLoggedIn != TRUE)
{
$this->load->view('templates/header');
$this->load->view('users/login', $data);
$this->load->view('templates/footer');
}
else
{
redirect('posts');
}
}
/**
* This function used to logged in user
*/
public function login()
{
$this->load->library('form_validation');
$data['title'] = 'Login';
$this->form_validation->set_rules('username', 'Username', 'required|max_length[128]|trim');
//$this->form_validation->set_rules('password', 'Password', 'required|max_length[32]|');
if($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header');
$this->load->view('users/login', $data);
$this->load->view('templates/footer');
}
else
{
$username = $this->input->post('username');
$password = $this->input->post('password');
$result = $this->user_model->login($username, $password);
if(count($result) > 0)
{
foreach ($result as $res)
{
$sessionArray = array('id'=>$res->id,
'username'=>$res->username,
'email'=>$res->email,
'mobile'=>$res->mobile,
'isLoggedIn' => TRUE
);
$this->session->set_userdata($sessionArray);
$this->session->set_flashdata('user_login', 'Welcome');
redirect('posts');
}
}
else
{
$this->session->set_flashdata('login_fail', 'Email or password mismatch');
redirect('users/login');
}
}
}
VIEW:
<?php echo $email; ?>

Answer 1

You are creating the session for user information
Try to fetch the session data :
echo $this->session->userdata('email');
or trying to pass the data in views $data

Answer 2

$email will not work because writing $email means ordinary variable but in your case you have to write like :
<?php echo $this->session->userdata('email'); ?>

Answer 3

If You are using flashdata, then You can get it using below code:
Controller
if (empty($this->session->userdata('UserID'))) {
$this->session->set_flashdata('flash_data', 'You don\'t have access!');
$this->load->view("initialHeader");
$this->load->view("login");
redirect('Login');
}
View
<?php if(!empty($this->session->flashdata('flash_data'))) {
?>
<div class="alert alert-danger">
<?php echo $this->session->flashdata('flash_data'); ?>
</div>
<?php } ?>
If You are using tmp data as a session, please refer below code:
Controller
<?php
if (!empty($data)) {
$this->session->set_userdata('permission_error_msg', $data);
$this->session->mark_as_temp('permission_error_msg', 10); // For 10 Seconds
$this->load->view('dashboard', array($title, $data));
} ?>
View
<?php if ($this->session->tempdata('permission_error_msg')) { ?>
<b class="login_error_msg"><?php
if (!empty($this->session->tempdata('permission_error_msg'))) {
echo $this->session->tempdata('permission_error_msg');
}
?></b>
<?php } ?>
Thank You.
