Code

function global_filter_set_value_on_session($form, &$form_state) {

  // $field_name = $form_state['global_filter_name']; does not work in D6
  $field_name = reset(array_keys($form_state['values']));

  // @todo: relying on field being the first array element is dodgy.
  $filter_value = isset($form_state['values'][$field_name]) ? $form_state['values'][$field_name] : '';
  $_SESSION['global_filter'][$field_name] = $filter_value;
  $form_state['rebuild'] = TRUE;
