CodeIgniter object controller not found - php

Question

I am using codeIgniter 3.x. I load a view containing a form that submits to User.php controller but whenever I hit the submit button it redirect to this url "http://localhost/signup/Users/register" and it always gives "Object not found! The requested URL was not found on this server."
following is my .htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /signup/index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 /signup/index.php
</IfModule>
following is autload helper in autload.php
$autoload['helper'] = array('url','form');
following is config.php
$config['base_url'] = 'http://localhost/signup/';
$config['index_page'] = '';
$config['uri_protocol'] = 'REQUEST_URI';
following is how I open a form and close it in Welcome.php view.
<?php echo form_open("Users/register", $attributes);?>
<?php echo form_close(); ?>
Following is Users.php controller
class Users extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper(array('form','url'));
$this->load->library(array('session', 'form_validation', 'email'));
$this->load->database();
$this->load->model('user_model');
$this->load->view('user_registration_view');
}
function index()
{
$this->register();
}
function register()
{
//set validation rules
$this->form_validation->set_rules('fname', 'First Name', 'trim|required|alpha|min_length[3]|max_length[30]|xss_clean');
$this->form_validation->set_rules('lname', 'Last Name', 'trim|required|alpha|min_length[3]|max_length[30]|xss_clean');
$this->form_validation->set_rules('email', 'Email ID', 'trim|required|valid_email|is_unique[user.email]');
$this->form_validation->set_rules('password', 'Password', 'trim|required|md5');
$this->form_validation->set_rules('cpassword', 'Confirm Password', 'trim|required|matches[password]|md5');
//validate form input
if ($this->form_validation->run() == FALSE)
{
// fails
$this->load->view('user_registration_view');
}
else
{
//insert the user registration details into database
$data = array(
'fname' => $this->input->post('fname'),
'lname' => $this->input->post('lname'),
'email' => $this->input->post('email'),
'password' => $this->input->post('password')
);
// insert form data into database
if ($this->user_model->insertUser($data))
{
// send email
if ($this->user_model->sendEmail($this->input->post('email')))
{
// successfully sent mail
$this->session->set_flashdata('msg','<div class="alert alert-success text-center">You are Successfully Registered! Please confirm the mail sent to your Email-ID!!!</div>');
redirect('user/register');
}
else
{
// error
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('user/register');
}
}
else
{
// error
$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Oops! Error. Please try again later!!!</div>');
redirect('user/register');
}
}
}

The problem with your htaccess so change it to default
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
And in config
$root=(isset($_SERVER["HTTPS"]) ? "https://" : "http://").$_SERVER["HTTP_HOST"];
$root.= str_replace(basename($_SERVER["SCRIPT_NAME"]), "", $_SERVER["SCRIPT_NAME"]);
$config["base_url"] = $root;

Answer 2

If your application is under your signup folder ( as it appears by your .htaccess file ) then you need to do the following...
.htaccess
This lives in the same folder as your application. i.e the same folder as the system index.php file.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
As your URL is http://localhost/signup/ which you have set correctly in your $config['base_url'] that should work.
I just created a dummy test site and tested it.
Let me know if that works.

Filename should be same as class name Users.php Class Users extends CI_Controller

Answer 4

I think you made mistake while redirecting ...
replace :
redirect('user/register');
with :
redirect('Users/register'); OR redirect('Users/register','refresh');
