CodeIgniter htaccess redirect url issues - php

Question

I want "nice urls" for my website. I'm looking at using .htaccess and I have tried many versions.
Now I have this:
IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine On
# !IMPORTANT! Set your RewriteBase here and don't forget trailing and leading
# slashes.
# If your page resides at
# http://www.example.com/mypage/test1
# then use
# RewriteBase /mysite
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
# Submitted by: ElliotHaughin
ErrorDocument 404 /index.php
</IfModule>
So this removes index.php from the URL. At first it was ok, but
Here is my config.php:
$config['base_url'] = 'localhost/mysite/';
$config['index_page'] = '';
$config['uri_protocol'] = 'AUTO';
And my .htaccess file is in my app root.
folder img
I need a login for admin page, so localhost/mysite/admin is the my url for admin site.
public function index()
{
// $this->session->unset_userdata('logged_in'); session_destroy();
$data['sitename']="Varkocs Old Pub";
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');
$data['username'] = $session_data['username'];
$this->load->view('admin/home_view', $data);
}
else
{
//If no session, redirect to login page
//redirect('login', 'refresh');
$this->load->helper(array('form', 'url'));
$this->load->view('admin/login',$data);
}
}
public function logout()
{
$this->session->unset_userdata('logged_in');
session_destroy();
redirect('', 'refresh');
}
This is my admin controller. I try here if logged in I load home_view, else the login view.
<div id="" class="container-fluid ">
<div id="" class="row">
<div id="" class="col-md-4 text-center admin_container">
<h2><?php echo $sitename;?><h4>belépés az admin felületre</h4></h2>
<?php echo validation_errors('<p class="bg-danger">','</p>');?>
<form action="verifylogin" method="post" accept-charset="utf-8">
<div class="form-group">
<label for="username">Username:</label>
<input class="form-control" placeholder="" type="text" size="20" id="username" name="username"/>
</div>
<div class="form-group">
<label for="password">Password:</label>
<input class="form-control" placeholder="password" type="password" size="20" id="passowrd" name="password"/>
</div>
<input class="btn btn-warning btn-lg btn-block" type="submit" value="Login"/>
</form>
</div>
</div>
This is the login view. I can't use here:
echo form_open('verifylogin');
Because it's returning the wrong URL.
So I write HTML:
<form action="verifylogin" method="post" accept-charset="utf-8">
The form validation with CodeIgniter is working. But the redirect afterwards doesn't work.
$this->load->helper(array('form', 'url'));
if($this->form_validation->run() == FALSE)
{
//Field validation failed. User redirected to login page
$data['sitename']="Varkocs Old Pub";
$this->load->view('admin/login',$data);
}
else
{
//Go to private area
redirect('admin', 'refresh');
}
I have tried many ways to fix this, but I failed.

The Codeigniter documentation says the following about the redirect function:
In order for this function to work it must be used before anything is outputted to the
browser since it utilizes server headers.
This rule can be tricky to follow. A space or line end before the opening PHP tag will already break it.
