How to Auto Login After Registration in WordPress with core php

Question

I\'ve been trying for days now to take users who have just registered to my WordPress site and automatically log them in and then redirect them to a URL of my choice. By def

Following is based on how WooCommerce creates a new user and logs him in:

$user_pass = esc_attr( $_POST['account_password'] );

$new_user_data = array(
    'user_login' => $_POST['account_username'],
    'user_pass'  => $user_pass,
    'user_email' => $_POST['account_email'],
    'role'       => 'subscriber'
);

$user_id = wp_insert_user( $new_user_data );

// Set the global user object
$current_user = get_user_by( 'id', $user_id );

// set the WP login cookie
$secure_cookie = is_ssl() ? true : false;
wp_set_auth_cookie( $user_id, true, $secure_cookie );

to redirect use wp_safe_redirect, e.g.

wp_safe_redirect( home_url( '/' ) );
exit;
