/* This file contains several functions for retrieving and manipulating
calendar events, birthdays and holidays.
array getBirthdayRange(string earliest_date, string latest_date)
- finds all the birthdays in the specified range of days.
- earliest_date and latest_date are inclusive, and should both be in
the YYYY-MM-DD format.
- works with birthdays set for no year, or any other year, and
respects month and year boundaries.
- returns an array of days, each of which an array of birthday
information for the context.
array getEventRange(string earliest_date, string latest_date,
bool use_permissions = true)
- finds all the posted calendar events within a date range.
- both the earliest_date and latest_date should be in the standard
YYYY-MM-DD format.
- censors the posted event titles.
- uses the current user's permissions if use_permissions is true,
otherwise it does nothing "permission specific".
- returns an array of contextual information if use_permissions is
true, and an array of the data needed to build that otherwise.
array getHolidayRange(string earliest_date, string latest_date)
- finds all the applicable holidays for the specified date range.
- earliest_date and latest_date should be YYYY-MM-DD.
- returns an array of days, which are all arrays of holiday names.
void canLinkEvent()
- checks if the current user can link the current topic to the
calendar, permissions et al.
- this requires the calendar_post permission, a forum moderator, or a
topic starter.
- expects the $topic and $board variables to be set.
- if the user doesn't have proper permissions, an error will be shown.
array getTodayInfo()
- returns an array with the current date, day, month, and year.
- takes the users time offset into account.
array getCalendarGrid(int month, int year, array calendarOptions)
- returns an array containing all the information needed to show a
calendar grid for the given month.
- also provides information (link, month, year) about the previous and
next month.
array getCalendarWeek(int month, int year, int day, array calendarOptions)
- as for getCalendarGrid but provides information relating to the week
within which the passed date sits.
array cache_getOffsetIndependentEvents(int days_to_index)
- cache callback function used to retrieve the birthdays, holidays, and
events between now and now + days_to_index.
- widens the search range by an extra 24 hours to support time offset
shifts.
- used by the cache_getRecentEvents function to get the information
needed to calculate the events taking the users time offset into
account.
array cache_getRecentEvents(array eventOptions)
- cache callback function used to retrieve the upcoming birthdays,
holidays, and events within the given period, taking into account
the users time offset.
- used by the board index and SSI to show the upcoming events.
void validateEventPost()
- checks if the calendar post was valid.
int getEventPoster(int event_id)
- gets the member_id of an event identified by event_id.
- returns false if the event was not found.
void insertEvent(array eventOptions)
- inserts the passed event information into the calendar table.
- allows to either set a time span (in days) or an end_date.
- does not check any permissions of any sort.
void modifyEvent(int event_id, array eventOptions)
- modifies an event.
- allows to either set a time span (in days) or an end_date.
- does not check any permissions of any sort.
void removeEvent(int event_id)
- removes an event.
- does no permission checks.
