How to get two drop downs to a single field in drupal? -


how 2 drop downs single field? example, time field 1 drop down hours(0-23) , other minutes(0-59).

if have custom module you're using on drupal 7 site, can include implementation of hook_form_alter makes transformation you. (see http://api.drupal.org/api/drupal/modules!system!system.api.php/function/hook_form_alter/7 detailed explanation of hook.)

basically, want hook form you're trying alter (perhaps testing $form_id in if clause make sure matches form want alter) , create 2 new fields hours , minutes, while hiding built-in field shows time you're trying store. here's example:

function mymodule_form_alter(&$form, &$form_state, $form_id) {   if ($form_id == 'my_form_id') {     $form['original_time_field']['#type'] = 'hidden';     $hours = array();     ($digit = 0; $digit < 24; $digit++) {       $hours[$digit] = $digit;     }     $minutes = array();     ($digit = 0; $digit < 60; $digit++) {       $minutes[$digit] = $digit;     }     $form['hours'] = array(       '#type' = 'select',       '#options' = $hours,       '#title' = t('hours'),     );     $form['minutes'] = array(       '#type' = 'select',       '#options' = $minutes,       '#title' = t('minutes'),     );   } }

then have couple choices. can either include custom .js file listens changes hours , minutes pulldowns , rewrites hidden time field value on fly, or can write custom submit handler form in question (using either form api or implementing appropriate hook_form_submit function) uses $form_state variable combine 2 virtual fields , write resulting value real time field.
