Custom shortcodes – retrieve normal WP user data?

Hello mailpoets,

I tried my best to find a way to retrieve user data that is stored in the wp user profile. Lets take the simple case of “last_name”. Here is what i tried and the results i got:

$replacement = 'hallo';
shortcode [custom:name] returned hallo – so the shortcode as such works and is inserted!

$replacement = $user_info->last_name;
returned [custom:name]

$replacement = $user_info->user_last_name;
returned [custom:name]

$replacement = get_userdata($user_info->user_last_name);
returned empty

$replacement = get_userdata($user_info->last_name);
returned empty

… trying to get user_info first by

$user_info = get_userdata($this->receiver->wpuser_id);
$replacement = $user_info->last_name;

returned “Request error not JSON”

funny thing for me as a noob is: replacing in shortcode.php line 185
$replacement = $user_info->display_name;
with
$replacement = $user_info->last_name;
works for shortcode: [user:displayname]!

I hope you can help me and others with a “user data” example 🙂

Thank you
Tobias
