redirect guest to login page

Is social Engine network has any plugins or coding that redirect guest to login page and guest can;t see home page.

click here for example now guest should redirect to login page


above is not my site it's just example

 

What language is the website coded in?

 

dude it's php

 

session_start();

function logged_in() {
return isset($_SESSION['user_id']);
}

function sendto( $location = NULL ) {
if ($location != NULL) {
header("Location: {$location}");
exit;
}
}

if (!logged_in()) {
sendto("login.php");
}


That will start a session, then if the user doesn't have a stored user_id in the session then he's not logged in so send him to the login page.
The user_id can be anything, but make sure your logged in members have them in their session else they'll be redirected aswell.
Hope that helps.

 

this script should be add in home.php right?

 

I'm not sure how your website is organised, so i can't tell you exactly where to put it.
The best way would be to put:

session_start();

function logged_in() {
return isset($_SESSION['user_id']);
}

function sendto( $location = NULL ) {
if ($location != NULL) {
header("Location: {$location}");
exit;
}
}

In a seperate .php file, call it something like "session.php" and save it to your includes folder. Then on any page you want people to be logged in for you put this at the very top:
<?php require_once("includes/sessions.php"); ?>
if (!logged_in()) {
sendto("login.php");
}

That bit of code needs to be at the very top though, before any html (and prefferably before any processing).

Hope that helps.

 

hey,

I believe that we are discussing above social networking, so could you clarify me this one?

 

yes we are

 

i think that will work

 

If you want to force users to login before seeing any page on your site then you'll want to include code similar to the above on EVERY page of the site in case a user arrives on some other page of the site. But I think you want to modify the above code slightly.

You'll likely want to get the original requested URL and store it in some sort of session variable before redirecting to the login page (or pass it to the login page in encoded form as a query string parameter on the URL when you redirect to the login). Once the user logs in then your login page can redirect the user to the page they originally requested using the session variable or query string parameter.
