I have been told that to make $searchable_fields based on members group or permissions I have to use a public function searchableFields() instead of a static $searchable_fields. However I cannot figure out the syntax.

I need one set of searchable fields for one user group and another set for another user group for the same DataObject.

I figured it would be:

public function searchableFields() {

$member = Member::currentUser();

$searchable_fields = array(
      'BestNotesID',
      'FirstName',
      'Surname',
      'Therapist.FirstName',
      'StudentGroup.Name'
   );

if ($member && $member->inGroups(array('office-staff', 'office-managers'))) {
$searchable_fields[] = 'OfficeLocation';
{

return $searchable_fields;
}

This code throws the error: Fatal error: Class 'B' not found in ....... sapphire/core/model/DataObject.php on line 1632

Thanks for the help, I got it working. Now I need to make one of the search fields a dropdown instead of a text field. Is there a way to do this? The dropdown would be populated with the names of DataObjects of a particular class.
