How to set auto login after a successfull registration page ?

Hi Long
Similar problem here
I followed your link and the autologin works well
But the extra fields I added in the registration form (custom and regular) are not saved anymore
Well, somehow it saves only the user_url
Before adding the autologin function data were all saved as aspected
It seems I'm using the wrong WP hook and the autolign fires before META plugin complete it's work
Any clues?

Here's my code:

add_filter( 'rwmb_meta_boxes', 'agri_new' );
function agri_new( $meta_boxes ) {
    $prefix = '';

    $meta_boxes[] = [
        'title'  => __( 'Submitter', 'agri' ),
        'id'     => 'user-extra',
        'type'   => 'user',
        'fields' => [
            [
                'name'     => __( 'Nome', 'agri' ),
                'id'       => $prefix . 'first_name',
                'type'     => 'text',
                'required' => true,
            ],
            [
                'name'     => __( 'Cognome', 'agri' ),
                'id'       => $prefix . 'last_name',
                'type'     => 'text',
                'required' => true,
            ],
            [
                'name'     => __( 'Telefono', 'agri' ),
                'id'       => $prefix . 'user_phone',
                'type'     => 'text',
                'required' => true,
            ],
            [
                'name' => __( 'Sito web', 'agri' ),
                'id'   => $prefix . 'user_url',
                'type' => 'url',
            ],
        ],
    ];

    return $meta_boxes;
}

Here's the custom function:

function auto_login_new_user( $user_id ) {
    wp_set_current_user($user_id);
    wp_set_auth_cookie($user_id);
    if(awr_user_has_role(get_current_user_id(), 'subscriber')){
      wp_redirect("/proponi-un-luogo/");
    }
    exit();
}
add_action( 'user_register', 'auto_login_new_user' );

Grazie mille! 🙂
Long you’re an angel… and I’m quite ashamed of my laziness… I should definitely pay more attention to the documentation. There’s already everything in it. Indeed is probably the best api documentation I ever used: clear, accurate, complete, in depth, useful. I love your great work every day more.
