Ability to change minute granularity?

This is what I've done to solve the issue:

1. Opened modules\event\event.module (version 1.215.2.12)
2. Edited line 1477
   • Before:
     for ($i = 0; $i <= 59; $i++) $minutes[$i] = $i < 10 ? "0$i" : $i;
   • After:
     for ($i = 0; $i <= 59; $i += 15) $minutes[$i] = $i < 10 ? "0$i" : $i;

Of course this patch will last until your next update of the Event module. So it probably would be better if granularity can be changed trough the Event admin page.

You can use hook_form_alter in your site specific module to change this.

Here's a simple example of what killes is suggesting - using hook_form_alter in your custom module to alter the form before presentation ... improvements welcome!

This approach avoids the tedious effort of having to patch the module on each update, or (worse) having to avoid updating modules because you don't have time to patch them today. It's much, much safer.

I would appreciate any critique on the code below.

function mymodule_form_alter($form_id, &$form) {
  switch( $form_id ) {
  case "event_node_form" :
    $elements = array( 'start', 'end' )  ;
    foreach( $elements as $element) {
      $el_date = 'event_'.$element ;
      $el_mins = $element.'_minute';
      if ( isset($form[$el_date]) && 
	   isset($form[$el_date]['date']) &&
	   isset($form[$el_date]['date'][$el_mins]) ) {
	     $form[$el_date]['date'][$el_mins]['#options'] = array( '00', '15', '30', '45' ) ;
      }
    }
  }
}
