Answer 1

To redirect to an anchor in CI you should use redirect function like this :

redirect('/controller/function#anchor', 'refresh');

Hope that helps

Answer 2

if ( $this -> form_validation -> run() === FALSE )
    {
        header('Location: http://www.example.com/');//your controller name

    }

Header Function

or

if ( $this -> form_validation -> run() === FALSE )
    {
         redirect('/login/form/', 'refresh');//your controller name

    }

Redirect

Answer 3

codeigniter redirection can be achieved using the redirect method in the url helper. You can use this like this

redirect('/your controller/method', 'refresh');

Where 'your controller' is the controller that houses the method for the view page for new event add. And the 'method' is the method name inside the controller that loads the view. For reference go to this link codeigniter url helper

Answer 4

This is how you can do it. First load the URL helper , then call the redirect() method

$this->load->helper('url');
redirect(base_url().'controller/method', 'refresh');
