Get page ID in user_register hook Wordpress

Question

in my site I have 2 differents forms for registration. The difference between them that is when I use the second I update a meta info for a user that normally is blank.

I've added the Facebook SSO and works fine only for the first form. When I use it for the second it doesn't recognize the origin and register the user as the first one (without update meta info).

I've tried to use the register_user hook

function myplugin_registration_save( $user_id ) {
    global $post;
    if ($post->ID == 816) {
        update_user_meta($user_id, 'user_type', 'couple');
    }
}

add_action( 'user_register', 'myplugin_registration_save', 999 );

but this hook doesn't return the post ID.

How can I detect I'm in the second form and launch the update_user_meta function when the post id is 816?

Thanks

Answer 1

function myplugin_registration_save( $user_id ) {
$currentPageId = get_the_ID();
 if ($currentPageId == 816) {
    update_user_meta($user_id, 'user_type', 'couple');
 }
}
add_action( 'user_register', 'myplugin_registration_save', 999 );

Try this one it will surely give you the current page id..
