Hi @deprela!

Sure! It’s just normal PHP so you can set choices to be whatever you need. You can use get_posts, wp_get_post_terms, or any other function to get the values and then set them as the choices (where the key is the value stored in the database and the value is the label presented to the user). You can even use the piklist function to pluck the values from collections:

piklist('field', array(
  'type'      => 'select',
  'field'     => 'related_post',
  'label'     => 'Related Post',
  'choices'   => piklist(get_posts(array(
    'post_type'   => 'post',
    'numberposts' => -1
  )), array('ID', 'post_title'))
));

Hope this helps!

Hi @Juan!

It sure is! Just like this:

piklist('field', array(
  'type'      => 'select',
  'field'     => 'staff_member',
  'label'     => 'Add Staff Members',
  'columns'   => 12,
  'value'     => '',
  'add_more'  => true,
  'choices'   => array('' => 'Select one post...') + piklist(get_posts(array(
    'post_type'   => 'staff',
    'numberposts' => -1
  )), array('ID', 'post_title'))
));

Notice two things here: First, I added a 'value' => '' line that tells Piklist what the default value of the field is when there’s no value saved, yet. Second, I added the array('' => 'Select one post...') + line. This adds an option to the beginning of the choices with a stored value of nothing, while displaying ‘Select one post…’

Hope this helps! 🙂
