Hello, I work almost one week on this problem and can´t think any furhter myself.
I´m new at codeigniter and in php programming as well.

I try to explain you my problem, but if you need more information please ask.

My routes:

PHP Code:
$route['default_controller'] = 'login';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE; 

In my controller' directory I have the file: login.php

PHP Code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login extends CI_Controller {
    
    public function index () {
        
        $this->load->view('first_message');
    }    
} 

The index function here loads the view: first_message.php

Code:
<html>

    <head>

       <title> Welcome to Rosa </title> 

    </head>

    <body>        

        <h2>Welcome to Rosa </h2>

       <?php            

        $username = filter_input(INPUT_POST, 'username', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

        $password = filter_input(INPUT_POST, 'password', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

        if (isset($username, $password)) {    

           if (!$username){

               //no username

            echo "Please enter a username.";

           }       

          if (!$password){

              //no Password

           echo "Please enter a password.";

          }       

        } 

       else {

           //Button isn´t set

       }

       ?>

        <form action='page1.php' method='post'>            

            Username: <input type="text" name="username"><br />

            Password: <input type="text" name="password"><br />            

            <input type='submit' value='Login'>

        </form> 

    </body>

</html>

So far, everything works fine. The URL in my browser is now: localhost/home
After typing the username and the password I push the "Login"-Button.

Now the browser links to this URL: http://localhost/home/page1.php to start page1.php:

PHP Code:
<?php
include_once 'application/views/second_message.php';
defined('BASEPATH') OR exit('No direct script access allowed');


class Page1 extends CI_Controller {
    
    
    public function index () {
        
        $this->load->view('second_message');
    }
    
} 

Instead, I get the error:

Object not found! The requested URL was not found on this server.

So, I hope it became clear what my problem is and I hope you can give me hint to solve it.

Thank you and best regards

Your page1 is it's own controller meaning the URL localhost/home/page1 will not work because page1 is not a method of the home controller.

Change the url to localhost/page1 or add the page1 method to your home controller.

It seems you don't understand the relation between URL and controller (file and name) in CodeIgniter.
See http://www.codeigniter.com/user_guide/general/urls.html
And it would be better you read http://www.codeigniter.com/user_guide/tu...index.html

Thank you for the hints.

Now I understand the constructs of an URL:
http://example.com/[controller-class]/[controller-method]/[arguments]

So, I know my page1.php should be a method of the controller-class login.php.

But I still don´t know how it helps me to open the view second_message.php if I click on the login-button.

So when I change to a method in the controller-class, what do I write in: .....action= ''..... Huh

If page1 is a method of your Controller Login then your URL would be
http://www.example.com/login/page1

And an action of a form points to a page...
