What I'm after is to simply redirect a user to the referring URL after they have logged in. I've been trying to figure this out for a few days now and I've read everything I possibly can, but either the posts I find are 4-5 years old or whatever posted code I try doesn't seem to work.

I'm on a multisite and would prefer something that would be applied to all subsites, but for now, I can settle with something that modifies each site individually.

Here's the latest I've tried which is code that I found somewhere but this continues to redirect the user to their profile on the admin side.

function redirect_after_login() {
    global $redirect_to;
    if (!isset($_GET['redirect_to'])) {
        $redirect_to = $refer;
add_action('login_form', 'redirect_after_login');

If anyone could point me in the right direction, that would be great!

  • Does your site use domain mapping? If so what plugin or code. Also, I'm not sure $redirect_to is a global reference. Nov 29, 2016 at 5:59

    Actually this code looks a bit squirrelly. There is no else to release the global, nor a proper return. Nov 29, 2016 at 6:02
  • You never set any redirect_to in your function parameters. That is required. Check it here: codex.wordpress.org/Plugin_API/Filter_Reference/login_redirect Nov 29, 2016 at 6:05
  • So is a return value Nov 29, 2016 at 6:07
  • Yes.. using WPMU DEV's Domain mapping plugin.

Your code is completely flawed - not to mention you can't redirect to the HTTP referer after login... because the referer is now the login page. Instead, use the login_redirect filter:

add_filter( 'login_redirect', function ( $redirect_to, $requested_redirect_to ) {
    if ( ! $requested_redirect_to ) {
        $redirect_to = wp_get_referer();

    return $redirect_to;
}, 10, 2 );

Note that we only override $redirect_to if $requested_redirect_to is "empty", otherwise:

  1. It will break the redirect_to URL parameter that both WordPress and many plugins use to set specific post-login redirects other than the default (too many times have I seen plugins completely break this feature).

  2. If we always set it to the referer, we'll end up with the login page itself (as mentioned earlier). This is because when a user first lands on the login page, WordPress sets a hidden redirect_to field with the value of $redirect_to. On subsequent page load (i.e. logging in), this becomes the $requested_redirect_to value.
