heres the scenario... you view a news story on a website so you want 2 post something back, so u log in, u get redirected to the main page again, which is quite annoying as you will have to go through all the links and pages again to get to where you were... how can i solve this by making the redirect go back?

this is what i have atm

Code:

$back = "<javascript:history.back(-1)>";

?>

<html>
<META HTTP-EQUIV="Refresh" CONTENT="1;URL=<? echo "$back"; ?>">
</html>

You could just make the login script to take you to the correct page instead of the mainpage.. include a hidden field in the form named redirect..

<input type="hidden" name="redirect" value="postcomment.php" />

then when you process the form with php check whether there is a value for the redirect box and if there is take them to that page specified otherwise just go to the main page..

PHP Code:


			
$redirect = $_POST['redirect'];

if($redirect) {

header('location: $redirect');

exit;

} else {

header('location: mainpage.php');

exit;

}

more reliable than using javascript.. saves the time to..

Nah, when you go to login, get the login PHP script to simply look up where the user just came from by using the pretty cool $_SERVER predifined.

Quote:

'HTTP_REFERER'
The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

to use this, use $_SERVER['HTTP_REFERER'];

You will have to get the login script to check that a) there is a refering page, if not what do you do!? b) check the refering page is actually your website

lol, ok then.. that doesnt really help

.. it does, but not the kinda answer im looking for... how can i make the javascript code into a variable to use? cos when it redirects it uses that in the browser? which is annoying

Not using java script as I don't know enough of it, but this is how I got around a similar problem using PHP, perhaps you can use it with your javascript somehow?

At the top of each page, except the login page use:

$_SESSION[currentPage] = $PHP_SELF;

Which will store the current page url you're looking at in a global session variable

When referring back to that page, ie. redirecting put this code at the top of the page maybe your login page or, the page that checks login details:

$currentPage = $_SESSION[currentPage];

And then after login is approved you can direct them to the page stored in the $currentPage variable
