Hello guys,
first post here, so sorry for not being too familiar with the forum. Ok so basically used the form loader:

Code:

class WebLogin extends CI_Controller {
        
    public function index(){    
        //$this->load->database();
        $this->load->helper('form');

        echo form_open('displaydetails/displayResults/');

        echo "Username : ". form_input('username', set_value('username'));
        echo "<br>Password : ". form_password('password', set_value('password'));
        echo form_submit('submit', 'Login');

        echo form_close();
  }
}

and then in the displaydetails/displayResults/ controller, I wrote simple echo:

Code:

class DisplayDetails extends CI_Controller {
        public function displayResults()
        {
        
            echo "form redirected correctly!";
        }
    }

then when I submit the login form, in the address bar the URL shows the following:

http://domainname.com/index.php/www.doma...layResults

as you can see twice the domain address is mentioned...why so? this is why I can't progress..
Thanks in advance.
