previous URL redirecting

[nuttynibbles]

hi,

as many of you have notice, if you were to go to (for e.g youtube) and you wanna post a comment, they require you to login. so you be redirected to login page and once login, they will redirect you back to the same page where you wanted to comment..

if im not wrong, we can use HTTP_REFERER to get previous url and save it into session??. but is there a better way??

You could always do like Yahoo does (or used to, anyway) and simply include the URL that they were previously at in the URL to the login page.

hmm okie tks. but i seems to have another problem=)

for e.g: a user wish to edit his profile by keying in http://example.com/user/editprofile in the browser and not click onto any link. while this url need login, he will be redirected to the login page. once login, how do i redirect user to the respective url he wished to go? how do i get the url key into the browser??

As I said, when you redirect them to the login page, you could always include the previous URL somewhere in the query string for the login page.

An alternative would be to store the previous page's URL in a session variable.

Some coding that I lifted, I haven't checked it.

In the authorisation checking page... send them to ur login page with current page attaached into the url.
$redirect = $_SERVER['PHP_SELF'];
header("Refresh: 5; URL=login.php?redirect=$redirect");

In the login page... once they're logged in, redirect them using the info from the URL
header ("Refresh: 5; URL=" . $_POST['redirect'] . "");

Indeed - might want to start by checking why $_POST is being used for something that was sent via the query string. 😉
