Show logged user info in browser, PHP php codeigniter - php

Question

I want to display current user info from database after login.
Here is my code.
Controller 1 (Welcome)
public function getValues() {
$this->load->model('display_model');
$result=$this->display_model->authenticateUser();
if($result){
$this->session->set_userdata('id', $result['id']);
redirect('/member/home/');
}
else
redirect('/welcome/');
Controller 2 (member)
public function __construct()
{
// Call the CI_Model constructor
parent::__construct();
if($this->session->userdata('id')==NULL)
{
redirect('/welcome/');
}
}
public function home() {
$this->load->view('member_home');
}
Model
public function authenticateUser(){
$name =$_POST['name'];
$password=$_POST['password'];
$where=array('name'=>$name,
'password'=>$password);
return $this->db->select('name, password, id')
->from('member')
->where($where)
->get()->row_array();
View 1 (login_view)
<h1>Member Login Form</h1>
<?php echo validation_errors(); ?>
<?php echo form_open('Welcome/getValues'); ?>
Username: <br/>
<input type="text" name="name" /> <br>
Password: <br>
<input type="password" name="password" /> <br>
<input type="submit" value="Login" name="submit"/>
</form>
View 2: After login view (member_home)
<?php
foreach($result as $row){
?>
<li><?php echo $row['first_name'].' '.$row['last_name'];?>
<br/><strong>Email: </strong><?php echo $row['email'];?>
</li>
Now error shows
Message: Undefined variable: result
How to solve it Need Help.. Thanks in Advance

Answer 1

You are not passing the $result value to your home view update the code as follows:
Controller 1:
public function getValues() {
$this->load->model('display_model');
$result=$this->display_model->authenticateUser();
if($result){
$this->session->set_userdata('id', $result['id']);
redirect(member/home/$result['id']);
}
else
redirect('/welcome/');
Controller 2:
public function __construct()
{
// Call the CI_Model constructor
parent::__construct();
if($this->session->userdata('id')==NULL)
{
redirect('/welcome/');
}
}
public function home($id = '') {
$data['id'] = $id;
$this->load->view('member_home',$data);
}
NOTE:
you must change the query result from row_array() to result_array() as you are using foreach on the view
