email link redirect

auddog

I'm creating a website that will email a link to users when someone submits a question, much like a help desk. They should be able to click the link which takes them to the website, but before they can do anything I want to make sure they login or already have logged in. Is there any tutorial that discuss this in detail. I can get the link to email, if they are already logged in I can get them to the correct page , but when they are not, I redirect them to the login page, I'm not able to get them back to the link after the login. Not sure what I'm missing, probably some with a url session???

you will have to stre the link somewhere so they can be sent to it after logging in, a session would seem the sensible option

if not logged in, set the link in session and send them to the login page, after logging in, if the session is set redirect them to that link.

This is what I'm currently using to try to capture the url before it's redirect since there is no session id, but no dice.

<?php
	//Start session
	session_start();

$url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME'];
    if (!empty($_SERVER["QUERY_STRING"]))
    $url .= "?".$_SERVER['QUERY_STRING'];


//set session for URL redirection if logged in correctly
$_SESSION['URL'] = $url;


//Check whether the session variable SESS_MEMBER_ID is present or not
if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) {
	header("location: index.php");
	exit();
}
?>

I'm not certain how to capture the url before anything else happens. Thanks for any help that you can provide.

dagon

are you saying $url is not populated or $_SESSION['URL'] is empty or what?

auddog

Either way, I get an undefined variable.

dagon

not psychic, you need to provide code used and exact error message.

I'm using the above code (auth.php) as an include to the pages that I need to make sure they are authenticated and to store the $url variable. When I make my call on my page


include 'auth.php';

and then run the page both IE6 and firefox will not display the page as it will be set to an endless loop. If I remove the include statement, the page works fine (albeit without the correct url / login feature).
