Thank you so much, the pireg_after_verification_users hook did do the trick!

In case anyone else could use it, here’s my aproach:

add_action( 'pireg_after_verification_users', 'zbx_verify_user' );
function zbx_verify_user( $user ) {
  $user_id = $user->ID;
  $invite_code = get_user_meta( $user_id, 'invite_code', true );

  if ( $invite_code && $invite_code != '' ) {
    // Get all users registered with this invite code
    global $wpdb;
    $user_ids = $wpdb->get_results( "SELECT user_id FROM {$wpdb->prefix}usermeta WHERE meta_key LIKE 'invite_code' AND meta_value LIKE '$invite_code'", ARRAY_A );

    // Sort out current user and clean up array
    $other_user_ids = array();
    foreach ( $user_ids as $val ) {
      if ( $val['user_id'] != $user_id )
        $other_user_ids[] = $val['user_id'];
    }

    // If any found, DELETE(!) other users
    if ( !empty( $other_user_ids ) ) {
      foreach ( $other_user_ids as $val ) {
        wp_delete_user( $val );
      }
    }

    // Deactivate invite code
    $wpdb->update(
      $wpdb->prefix.'pieregister_code',
      array( 'status' => 0, ),
      array( 'name' => $invite_code ),
      array( '%d' ),
      array( '%s' )
    );
  }
}

Careful, I assume that there aren’t any legit users with the same invite code, so I delete all other users. Keep this in mind when using this code.

Thanks for your reply! I’m using the premium version, but iviting through email isn’t an option in my case: My customer wants/needs to hand out invitation codes to yet unknown users in “real life” so they can come back to the website and register.

Does Pie Register offer any hooks? Couldn’t find anything about that in the documentation, but it seems there are some?

Great @hcabrera, you hit it!

I’ve added ‘wordpress-popular-posts’ to the allowed REST API namespaces in WP Cerber, and I immediately can see some counts. Pretty cool.

Many thanks to you!

Sorry @aaronrobb, I should have posted the result of my research here.

It was the plugin “Related Posts for WordPress” from Never5. They (quite silently) released a new subscription-based version of their plugin. We’ve had the previous premium version installed, which was a one-time payment plugin.

By the way, when looking closer at the dev tools image (https://ibb.co/mWZsJw), I see that there’s no href value at all. Strange, isn’t it?

In my function.php, $EM_Event->categories didn’t work. But with a little trying, I came to this solution:

add_filter( 'body_class', 'add_event_category_to_body_class');
function add_event_category_to_body_class( $classes ) {
  if ( em_is_event_page() ) {
    global $post;
    $EM_Event = em_get_event($post->ID, 'post_id');
    $classes[] = $EM_Event->output('#_CATEGORYSLUG');
    return $classes;
  }
}

This does exactly what I asked for, except one thing: if there’s an event that has assigned more than one category, this will only output one. I think it’s always the one with the highest ID. Don’t know if that’s an error in my function or if $EM_Event->output(‘#_CATEGORYSLUG’) does only return one category.

Thanks very much for your detailed explanation! I did it, was easy peasy indeed. 🙂
