I would like to remove the where clause for the city and postal_code filter field. I found the code below for D6 but it's not working.

<?php
function distprox_mini_views_query_alter(&$view, &$query) {
  if ($view->name == 'search' && $view->current_display == 'page_3') {
    // Remove the exposed filter conditions from the WHERE clause (WHERE city = MyCityInput)
    // and remove the corresponding args that were passed via the exposed filters
    // This effectively turns the city and zip code exposed filters into just text fields
    // that get used in distprox_mini_exposed_filter_proximity();

    $city = $view->exposed_raw_input['city'];
    $zip = $view->exposed_raw_input['postal_code'];

    // Remove the city or zip arguments (from the exposed filters)
    foreach ($query->where[0]['args'] as $key => $arg) {
      if ($arg == $city || $arg == $zip) {
        unset($query->where[0]['args'][$key]);
      }
    }

    // Remove the corresponding WHERE clause additions
    foreach ($query->where[0]['clauses'] as $key => $clause) {
      if (strpos($clause, 'postal_code') !== FALSE || strpos($clause, 'city') !== FALSE) {
        unset($query->where[0]['clauses'][$key]);
      }
    }
  }
}
?>
