Populating a select field documentation

A suggestion for documentation…

I spent quite a while figuring out how to populate a select element with the fields from field group. all the code I was able to find online was for older versions than V5 and didn’t work. In the end I got it to work like this. I wonder if this is the right way to do it but at least it works… If this is valid, this could be a worthwhile addition to this page: http://www.advancedcustomfields.com/resources/dynamically-populate-a-select-fields-choices/

function acf_load_select_choices( $field ) {

  global $wpdb;
  $group_slug = 'Name or slug of the group';

  $group_ID = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name =  '$group_slug' "); 
  if (empty($group_ID))
    $group_ID = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_title =  '$group_slug' ");

  $field['choices'] = array();
  $fields = acf_get_fields_by_id($group_ID);

  // to see what $fields contains, use:
  echo '<pre>'.var_dump($fields).'</pre>';

  if( $fields ) {
    foreach( $fields as $fieldrow ) {
      $field['choices'][ $fieldrow['name'] ] = $fieldrow['label'];
    }
  }

  return $field;

}

add_filter('acf/load_field/name=selectfieldname', 'acf_load_select_choices');

Hi @aatospaja,

Thank you for sharing the code, we will surely make arrangements to add this to the ACF resource page, it will surely come in handy to another dev.

Great work!!
