Changing drupal view filter from greater than to less than

Question

I have a drupal view I've created for events, each event has a date field I'd like to create a way either in the view itself or via the API to have an option for users to select all events, past events or future events. I've created a basic filter event_date > now which works, however I can't seem to change this to event_date < now via the views API.

I think you should create a module for that. Acces the api and use it. You should see this pages also:

function theme_test_form($form) {
  $output = '';
  $output .= drupal_render($form['name']);
  $output .= '<div class="foo">';
  $output .= drupal_render($form['access']);
  $output .= '<div class="bar">';
  $output .= drupal_render($form['details']);
  $output .= '</div></div>';
  $output .= drupal_render($form);
  return $output;
