How to get current logged in user in Wordpress Multisite outside of it?

I tried the method for Wordpress Singlesite and it give the error Call to a member function set_prefix() on a non-object on code line $wpdb->set_prefix( $table_prefix, false ); location wp-includes/ms-settings.php:196.

I think there should be a way to do it properly without exporting a bunch of functions from Wordpress.

Piece of code ($root = ABSPATH . '/sf/app'):

    $root = $this->container->getParameter('kernel.root_dir');
    require_once(realpath($root . '/../../wp-load.php'));
  • I don't know what you mean by 'outside' of it? Are you trying to implement an AJAX endpoint? If so you should never use a standalone file, use the WP AJAX api instead and this problem vanishes. Standalone form and ajax files are major security holes – Tom J Nowell Feb 16 '15 at 13:32
  • I have to use wordpress login system in Symfony framework. The login should be made on Wordpress pages. – Marin Bînzari Feb 16 '15 at 13:34
  • That sounds cumbersome, is there not a WP auth bundle? Your question essentially boils down to "How do I bootstrap/load WordPress in an external script?" – Tom J Nowell Feb 16 '15 at 14:16
  • @TomJNowell, yes, it is. – Marin Bînzari Feb 16 '15 at 14:22
  • Can you provide a more comprehensive example of what you've done so far? Not everybody here knows Symfony and incomplete snippets don't provide a lot of context, it might help – Tom J Nowell Feb 16 '15 at 14:24

Have you tried including the wp-load.php file in your external script ?

  • Yes I tried this. And it gives the error Call to a member function set_prefix() on a non-object. – Marin Bînzari Feb 16 '15 at 13:34
  • Could you please paste here the code you're using to include the wp-load.php file ? Or any other relevant code, it's hard to help you without some samples of what you've done so far :) – cristian.raiber Feb 16 '15 at 13:39
  • I updated my question. $root . '/../../' is my wordpress folder. – Marin Bînzari Feb 16 '15 at 14:06

    You can't use the $wpdb object without declaring global $wpdb – Tom J Nowell Feb 16 '15 at 14:23
  • @TomJNowell, strange, but it helped. You can write an anwer and I'll accept it. – Marin Bînzari Feb 16 '15 at 15:13
