Steven, Check out p. 177 of the Drupal 5 version of "Pro Drupal Development". There's a little code snippit that might be of interest: A select element example from statistics.module follows: $period = drupal_map_assoc(array(3600, 10800, 21600, 32400, 43200, 86400, 172800, 259200, 604800, 1209600, 2419200, 4838400, 9676800), 'format_interval'); /* Period now looks like this: Array ( [3600] => 1 hour [10800] => 3 hours [21600] => 6 hours [32400] => 9 hours [43200] => 12 hours [86400] => 1 day [172800] => 2 days [259200] => 3 days [604800] => 1 week [1209600] => 2 weeks [2419200] => 4 weeks [4838400] => 8 weeks [9676800] => 16 weeks ) */ $form['access']['statistics_flush_accesslog_timer'] = array( '#type' => 'select', '#title' => t('Discard access logs older than'), '#default_value' => variable_get('statistics_flush_accesslog_timer', 259200), '#options' => $period, '#description' => t('Older access log entries (including referrer statistics) will be automatically discarded. Requires crontab.') ); On 12 May 2011 20:00, <development-request@drupal.org> wrote:

I maintain a number of modules that are related to doing something at a user defined interval, e.g. every 30 minutes or 12 hours etc. Most times I just use a single select box and pre-generate some options that I think users will want, but of course some users (myself included) want to be able choose an exact, but custom, interval.

Is there any module out there that provides a generic 'interval' form element?

I've looked at core, and it just uses some custom code each time to generate a list of intervals and pop them in a select list. I've also looked at other contrib modules and some of them just provide a textfield and others provide a textfield for numeric input and a select list for 'units'. There doesn't seem to be a catch-all solution that I can find, and everyone seems to implementing intervals in a slightly different way.

In one of my module, I use a select list with prefined values to quickly fill a textfield with a choice. Then user can modify this textfield if they don't like any of these predefined values.
