Redirecting issues with CodeIgniter - php

Question

I have a login script, and when the login is successful I want it to redirect them to the home page(welcome_message.php) for some reason it does not link me to this file, instead throws a 404 and says "The requested URL "http://localhost/musiclear/index.php/views/welcome_message" cannot be found or is not available. Please check the spelling or try again later."
I am using CodeIgniters redirect() function for the change.
function validate_credentials() {
$this->load->model('membership_model');
$query = $this->membership_model->validate();
if ($query) { // if users credentials validated
$data = array('usernames' => $this->input->post('username'),
'is_logged_in' => true);
$this->session->set_userdata($data); //set session data
redirect('welcome_message'); //redirect to home page
} else { //incorrect username or password
$this->index();
}
}

Answer 1

Try passing the full URI to the redirect function like so:
redirect(base_url('views/welcome_message'));
Assuming of course that your controller is Views and page (function) is welcome_message

Answer 2

You can't redirect browser to view file directly, but You can redirect it to controller, which will show Your view. In Your example You're trying to access CodeIgniter's (which based in musiclear folder on Your localhost) Controller with name views and call welcome_message() method from it. But if Your really want to show it You must have next structure:
musiclear/
Application
Controllers
views.php
and views.php content:
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Views extends CI_Controller {
function index() {
// default action, required method
}
function welcome_message(){
$this->load->view('welcome_message');
}
}
?>

Answer 3

actually when you make redirects in CodeIgniters it looks up for your controller and you should load view through the function of controller. e.g:
function validate_credentials() {
$this->load->model('membership_model');
$query = $this->membership_model->validate();
if ($query) { // if users credentials validated
$data = array('usernames' => $this->input->post('username'),
'is_logged_in' => true);
$this->session->set_userdata($data); //set session data
redirect(base_url().'home/welcome'); //redirect to home function
} else { //incorrect username or password
$this->index();
}
}
function welcome(){
$this->load->view('welcome_mesage');
}

May be you forgot that redirect() function work only for controller class ie.
let you have welcomeclass so you can redirect it by using
redirect('wolcome');
you also redirect a function of controller class
if you want to redirect to page function of welcome controller class so you will writr
redirect('welcome/page');
