Custom action on login and "remember me"

Question

I try to call a function everytime a user login to website.

I succeeded with the wp_login hook for user who fill the login form.

However I can't find a hook for an user which has the "remember me" option activated when he come back to website (so he already have a login cookie).

I checked wp_validate_auth_cookie() function but this one is fired on each page: is Wordpress doing a check for "remember me" cookie on each page and then set user logged?

Thanks

Answer 1

Don't use wp_login hook. Use wp_signon function instead.

https://developer.wordpress.org/reference/functions/wp_signon/

wp_signon( array $credentials = array(), string|bool $secure_cookie = '' )

The credentials is an array that has ‘user_login’, ‘user_password’, and ‘remember’ indices. If the credentials is not given, then the log in form will be assumed and used if set.

Answer 2

wp_login hook pass two parameters: $user->user_login (string) and $user ( WP_User ). "remember me" option on login form did not pass on wp_login hook, its used on the wp_signon function to set the cookie on the browser.

wp_set_auth_cookie($user->ID, $credentials['remember'], $secure_cookie);

So you can't access that using wp_login hook.

It's not 100% clear what you are trying to do, but in order to get the Remember Me status, you can do the following:

1. Call wp_set_auth_cookie( $user_id, $remember ), where $remember is the Remember Me status.
2. If you need to customize the actual session length based on the Remember Me setting, add a filter for the cookie expiration: add_filter( 'auth_cookie_expiration', 'get_expiration' ), 10, 3 ); with:

function get_expiration( $expiration, $user_id, $remember ) {
    // $remember will be passed from wp_set_auth_cookie()
    if ( $remember ) {
        // ...
    } else {
        // ...
    }
}

I know this is an old question but from what I understand, OP needs to call a custom function every time a user logs in (regardless of if it's via the login form or automatically logging in as a result of checking the Remember Me option during a prior login).
This can be achieved by using the 'authenticate' filter. More information can be found in this helpful guide that I found.
