How do i stop going back and redirect the user to the homepage.

P.S i have a login module that has a parameter logout redirect page : have set it to the homepage menu that appears in the checkbox.

Answer 1

It seems that you want non-logged in users to access only homepage of your site.

Obviously if you redirect them on logout then user can always go back to any other url.

What i suggest, you should create a system plugin for this which will check whether user is logged in or not. And if user is not logged in then redirect him to the homepage.

You can apply this checking on joomla event onAfterRoute()

function onAfterRoute()
{
  $userId = JFactory::getUser()->id;
  
  //if user is not logged-in redirect to home-page
  if(!$userId){
     JFactory::getApplication()->redirect("index.php");
  }

}

Answer 2

It's not a very beautiful thing, but I think it may work:

Step 1:

On logout redirect the user to your home page, adding just a little $_GET variable. Redirect Link should be

http://www.yourdomain.com/index.php?logged_out=1

Step 2:

Insert, into this page or your Joomla Template index.php, a script that will prevent the back button from functioning whenn the variable $_GET['logged_out'] is set. This part is really tricky, because no method to my knowledge will actually work in every situation. The easiest way to disable the back button is IMO to actually fool it:

<?php 
    if (isset($_GET["logged_out"])){
       echo '<script type="text/javascript">window.location.replace('.JURI::base().');</script>';
    }
?>

This will redirect the user to your home page another time. As I said, it is not very beautiful, but I doubt that there are beautiful ways to do at all. In fact, I would strongly suggest to evaluate if this is truly necessary.
