Question

I have a web page, let’s call it main.php which displays an image of football field and some players distributed on the field. However, that page uses list.php as a right side frame that loads a list of players.

What happens is, when the user clicks on a player on the field (main.php), let’s say on the image of the Goal Keeper (GK), a list of GKs from world wide teams will load in right list fram (list.php). This is by using ajax.

So far we are good.

The current situation is, when session times out and the user clicks on a player from the field, the list on the right does not load, instead, list of players disappears from the list and a message says "Please login" is displayed on the right side frame (list.php)

The objective is, when session times out I want the whole website to redirect to the main page index.php

The problem is, I already put the redirecting code just before the code that is responsible of displaying the message "Please login". But what happened is, the redirection happens from within the frame, so i ended up having main.php displaying the field, and list.php displaying the main page!

Here’s the code I added.

$user_id = NSession::get('user_id');
 if (!isset($user_id))
{
        NSession::removeall();         
        General::Redirect('index.php');
}

They are using Smarty. and btw, I added the same code to top of main.php, and now if user tries to access main.php without logging in, it will redirect him to the main page, so the code works!

n.b. The project is not mine, it belongs to the company I work in.
And I don’t know which code is checking the session, all what I know is, if the user click on a player from the field after the session timeout, the "Please Login" message will be shown in the frame.

Answer 1

I’m guessing the redirect is essentially the same as using a header() function. It isn’t possible to specify a target using a php redirect as it is server-side – specifying the target is client-side.

You would need to print something like this to the screen:

<script type="text/javascript">window.open('index.php','_parent');</script>

And that will redirect the user to the index.
