使用GET后无法重定向到上一页

Question

I have a function that is displaying a shopping cart and products, and so after a product is added (which happens via GET) I want it to return to regular domain.

This is the code that updates the cart:

$page = $_SERVER['PHP_SELF'];

// if the product is added to the cart
if (isset($_GET['add'])) {
    $_SESSION['cart_'.$_GET['add']]++;
    header('Location: '.$page);
    // echo 'added';
}

Right now the cart is displayed on my homepage, which is http://localhost/tester/ , and after a product is added the url becomes http://localhost/tester/?add=1, but then I want it to revert back to http://localhost/tester/ but I cannot get it to do that.

Any ideas?

Answer 1

How about using parse_url()

exit(header('Location: '.parse_url($_SERVER['PHP_SELF'],PHP_URL_PATH)));
