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:

    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!!
