Offer the ability to jump forward or back more than one month at a time

Any luck with this? I've been trying to figure it out with no luck.

I'll give this a try. Thanks.

It would be nice to be able to keep in place any filters that have already been set as well

I've spent a bit of time on this today and attach a patch that gives admins the option to include a jump-to-date control on calendar pages. The control has a dropdown select menu for days, months and years (only years that have events in are included) and a button to jump to that date. Any filters that are already applied should be remembered.

I didn't want to do the autosubmit because it would mean doing it for each dropdown and would force someone to refresh the page three times when trying to enter a date.

Here's a patch for Drupal 5 too. I can't get any of the filters at the top of the calendar to actually work in the Drupal 5 version though, which could be a separate issue (the drupal_goto commands do not appear to be being called).

It looks like this is related to a change in the way the forms are structured (no longer $_POST['edit']['event_type_select'], for example, but $_POST['event_type_select']). Changing these values helps it work a little better, though seemingly intermittently. I've read somewhere that $_POST use should be dropped in favour of $form_values but that variable doesn't seem to yield any values.

+1 on this patch. Thanks for your work on this, geodaniel.

I used it to patch Event 5.x and found it very useful. Two minor corrections:

First, as geodaniel suggested in his January 22 comment, the post section should be changed to the following to remove the [edit] element:

  if ($_POST['event_day_select'] || $_POST['event_month_select'] || $_POST['event_year_select']) {
    drupal_goto('event/'. $_POST['event_year_select'] .'/'. $_POST['event_month_select'] .'/'. $_POST['event_day_select'] .'/'. $view .'/'. ($types ? $types : 'all') .'/'. ($tids ? $tids : 'all'));
  }

Secondly, when defining the default selection for the month select box, the patch needs to strip the leading zero off of the $curmonth variable so that it matches up with the correct month in the array. Here's how I corrected the code with ltrim():

function event_date_jump_form($curday, $curmonth, $curyear) {
  $days = drupal_map_assoc(range(1,31));
  $months = array(1 => t('January'), t('February'), t('March'), t('April'), t('May'), t('June'), t('July'), t('August'), t('September'), t('October'), t('November'), t('December'));
  $year_min = gmdate('Y', variable_get('event_range_prev', 0));
  $year_max = gmdate('Y', variable_get('event_range_next', 0));
  $years = drupal_map_assoc(range($year_min, $year_max));
  $curmonth = ltrim($curmonth, 0);

  $form['event_day_select'] = array(
    '#prefix' => '<div class="container-inline">',
    '#type' => 'select',
    '#default_value' => $curday,
    '#options' => $days);
  $form['event_month_select'] = array(
    '#type' => 'select',
    '#default_value' => $curmonth,
    '#options' => $months);

Event for Drupal 8 is unrelated to older versions. If an issue similar to this one exists, please open a new issue with the 8.x branch.
