redirecting user back from the page he came after login

[realin]

hi guys,

this one is simple for you :P

its like.. after login how would i redirect the user back to the page he came from ..

first i have to choose a language ?
shall i do it in JS or php using window.location or header respectively ?

Second thing i want to know is how to send the URLs from one page to another, shall i use an array which is passed on everypage ? or i should use a hidden field ?


thanks and regards
Realin !

Hi.

You could save the $_SERVER['HTTP_REFERER'] url on entering the login page, and then redirect to that url once the login form has been submitted and processed.

Something like:
[code=php]
# Check if the form has been submitted
if(isset($_POST['formSubmitButt on'])) {
# Process the form

# Redirect
header("Locatio n: ". $_SESSION['loginRedirect'];
}
else {
# Save the referer URL
$_SESSION['loginRedirect'] = $_SERVER['HTTP_REFERER'];

# Print your form
}


[/code]
