PHPTemplate generates php foreach() warnings when file.tpl.php exists in a custom template for CCK field templating

The sample template.tpl.php included with CCK has callback code that, when used in PHPTemplate, generates a host of php "Invalid argument supplied for foreach()" warnings when phptemplate_field() and field.tpl.php gets copied to a custom template file.

The code reference is at the bottom of the function:

  return _phptemplate_callback('field_devices', $variables, 'field-'. $field['field_name']);

The reference as written causes phptemplate.engine, function _phptemplate_default() to generate PHP errors because it expects the third parameter ($suggestions) to be an array -- and the callback is passing a scalar.

Converting the Suggestion reference to pass an array resolves those warnings:

  return _phptemplate_callback('field_devices', $variables, array('field-'. $field['field_name']));
