@kattagami– Piklist actually has a filter to help you do this: piklist_empty_post_title. I just tested it and there is a small bug which I fixed, and will be in the next version of Piklist. Try this:

1) Open class-piklist-cpt.php and find the wp_insert_post_data function. Change the IF statement to this:
if (($data['post_status'] != 'auto-draft') && (($data['post_title'] == 'Auto Draft') || empty($data['post_title']))). That fixes the bug.

2) Here’s your function:

function set_cpt_organizer_title($data, $post_array)
{
  if ($post_array['post_type'] == 'organizer')
  { 
    if((isset($post_array['_post_meta']['firstname'][0])) || isset($post_array['_post_meta']['lastname'][0]))
    {
      $full_name = $post_array['_post_meta']['firstname'][0] . ' ' . $post_array['_post_meta']['lastname'][0];
      return $full_name;
    }
    else
    {
      return $post_array['post_title'];
    }
  }
  else
  {
    return $post_array['post_title'];
  }

}
add_filter('piklist_empty_post_title', 'set_cpt_organizer_title', 10, 2);

3) The WordPress $post_array array returns all the data from your post including meta, so you don’t need to use get_post_meta.

Let me know if this works. If there are no issues we’ll document it and write a tutorial.

@pupppet– Showing/hiding seems to be a bug with the relate field. Supporting multiple scopes is interesting. I just tested multiple scopes like this 'scope' => array('post','page') and it seemed to work, but throws a bunch of warnings since most Piklist functions are not expecting an array. We’re going to have to think through if, and how, we want to support this.

@jason– I believe you want Nested fields, and there’s an example in Piklist Demos:
add new demo > lists > radio fields > nested fields.

@phila– Piklist still has a few kinks to work out with Windows installs. We’ll take a look at this one.

Try this: add_filter('user_can_richedit', '__return_false', 11);

@pupppet– Please provide a code snippet.

We just released v0.9.3.2 which contains this fix so it’s safe for you to update.

Can you post some code for us to review?
