1 date.theme.inc theme_date_display_combination($variables)

Returns HTML for a date element formatted as a Start/End combination.

$entity->date_id If set, this will show only an individual date on a field with multiple dates. The value should be a string that contains the following values, separated with periods:

  • module name of the module adding the item
  • node nid
  • field name
  • delta value of the field to be displayed
  • other information the module's custom theme might need

Used by the calendar module and available for other uses. example: 'date.217.field_date.3.test'

$entity->date_repeat_show_all If true, tells the theme to show all the computed values of a repeating date. If not true or not set, only the start date and the repeat rule will be displayed.

$dates['format'] The format string used on these dates $dates['value']['local']['object'] The local date object for the Start date $dates['value2']['local']['object'] The local date object for the End date $dates['value']['local']['datetime'] The datetime value of the Start date database (GMT) value $dates['value2']['local']['datetime'] The datetime value of the End date database (GMT) value $dates['value']['formatted'] Formatted Start date, i.e. 'February 15, 2007 2:00 pm'; $dates['value']['formatted_date'] Only the date part of the formatted Start date $dates['value']['formatted_time'] Only the time part of the formatted Start date $dates['value2']['formatted'] Formatted End date, i.e. 'February 15, 2007 6:00 pm'; $dates['value2']['formatted_date'] Only the date part of the formatted End date $dates['value2']['formatted_time'] Only the time part of the formatted End date
