First check user is login or not

if(isset($_SESSION['username'])){
$url='cart.php';
}else{
$url='login.php';
}
<a href="<?php echo $url; ?>">add to cart</a>

You have to pass the variables for your reference to know from which page you are coming.

You have to use header() for this.

session_start();// beginning of your file.
if(user is logged in) {
     start checking for conditions here.
     if($_GET['from'] == "checkout"
          $file="checkout.php";
     else
          $file="index.php";

     header("Location: $file");// file to which you want to redirect after login.
} else {
     // redirect to login page.
}

You can pass from where you are coming to this page, then check that is user is logged in, then decide where to redirect.

Probably it would be quicker for you to Google this first than to take the time typing it into StackOverflow and waiting to monitor responses, but who's to say. Maybe your browser was already open on this page and you're using an old dialup modem so loading new non-cached content is very slow.
