PHP, sign in then return to previous page

Good day. When a user signs in on my website, they are automatically redirected to the "Member's Area" section of the website. How can I make it so that they are redirected to the page they were on before signing in. (eg. thread in a forum)? Thanks

Hello,

I have edited it to redirect back two pages insted of displaying member area.
It displays Do you want to go to member area or back to previous page. If they click member area it goes to member area. If they click back it goes back 2 pages. (Or back to previous page)
PHP Code:

if ($signout == "true")
{
session_start();

Can you test it and tell me if it works?

Here is an edited version without the error.

$username = $_POST['username'];
$password = md5($passwordbeforemd5);
????: NamePros.com http://www.namepros.com/showthread.php?t=133907

$query = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'") or die(mysql_error());

$i=0;

$sesaccount = mysql_result($query,$i,"account");

$i++;
}



session_register("username", "password", "sesid", "sesaccount");

$sql = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password' LIMIT 1");


$login_check = mysql_num_rows($sql);

Many thanks iNod. I made a few ammendments but when the "previous page" link is clicked, it takes the user back to the sign in page. Example:

http://www.darkfx.co.uk/darkfx/signin.php

username: username
password: password

Thanks again

Do this

Change
Click <a href='#' onclick='javascript:history.back(2)'>here</a> to return to previous page.

To
Click <a href="javascript:history.go(-2)()">here</a> to return to previous page.

why not when you click Sign Url button have something like this:

href="signin.php?r=http://www.yoursite.com/blah/prevoiuspageblah.php"

and you could just store "r" in a session/cookie/or a hidden form field



i use a hidden form field

and then instead of doing javascript(-2) or something like that, you get an exact url for the visitor to use (in case user doesnt allow javascript? lol)

Ah sorry didn't read the whole thread.

This should do the trick

<a href = "javascript:history.back(-2)"> Go back </a>

I don't think you can do that you would need to track him on every page he visits because HTTP_REFERRER only works on some browsers and isn't always correct.

It wouldn't be using http_referrer it would be actually getting the URL of the current page and just adding it to the signin link

but you know a simplier way, nice
