Chris@76 17 /* This file contains several functions for retrieving and manipulating
Chris@76 18 calendar events, birthdays and holidays.
Chris@76 19
Chris@76 20 array getBirthdayRange(string earliest_date, string latest_date)
Chris@76 21 - finds all the birthdays in the specified range of days.
Chris@76 22 - earliest_date and latest_date are inclusive, and should both be in
Chris@76 23 the YYYY-MM-DD format.
Chris@76 24 - works with birthdays set for no year, or any other year, and
Chris@76 25 respects month and year boundaries.
Chris@76 26 - returns an array of days, each of which an array of birthday
Chris@76 27 information for the context.
Chris@76 28
Chris@76 29 array getEventRange(string earliest_date, string latest_date,
Chris@76 30 bool use_permissions = true)
Chris@76 31 - finds all the posted calendar events within a date range.
Chris@76 32 - both the earliest_date and latest_date should be in the standard
Chris@76 33 YYYY-MM-DD format.
Chris@76 34 - censors the posted event titles.
Chris@76 35 - uses the current user's permissions if use_permissions is true,
Chris@76 36 otherwise it does nothing "permission specific".
Chris@76 37 - returns an array of contextual information if use_permissions is
Chris@76 38 true, and an array of the data needed to build that otherwise.
Chris@76 39
Chris@76 40 array getHolidayRange(string earliest_date, string latest_date)
Chris@76 41 - finds all the applicable holidays for the specified date range.
Chris@76 42 - earliest_date and latest_date should be YYYY-MM-DD.
Chris@76 43 - returns an array of days, which are all arrays of holiday names.
Chris@76 44
Chris@76 45 void canLinkEvent()
Chris@76 46 - checks if the current user can link the current topic to the
Chris@76 47 calendar, permissions et al.
Chris@76 48 - this requires the calendar_post permission, a forum moderator, or a
Chris@76 49 topic starter.
Chris@76 50 - expects the $topic and $board variables to be set.
Chris@76 51 - if the user doesn't have proper permissions, an error will be shown.
Chris@76 52
Chris@76 53 array getTodayInfo()
Chris@76 54 - returns an array with the current date, day, month, and year.
Chris@76 55 - takes the users time offset into account.
Chris@76 56
Chris@76 57 array getCalendarGrid(int month, int year, array calendarOptions)
Chris@76 58 - returns an array containing all the information needed to show a
Chris@76 59 calendar grid for the given month.
Chris@76 60 - also provides information (link, month, year) about the previous and
Chris@76 61 next month.
Chris@76 62
Chris@76 63 array getCalendarWeek(int month, int year, int day, array calendarOptions)
Chris@76 64 - as for getCalendarGrid but provides information relating to the week
Chris@76 65 within which the passed date sits.
Chris@76 66
Chris@76 67 array cache_getOffsetIndependentEvents(int days_to_index)
Chris@76 68 - cache callback function used to retrieve the birthdays, holidays, and
Chris@76 69 events between now and now + days_to_index.
Chris@76 70 - widens the search range by an extra 24 hours to support time offset
Chris@76 71 shifts.
Chris@76 72 - used by the cache_getRecentEvents function to get the information
Chris@76 73 needed to calculate the events taking the users time offset into
Chris@76 74 account.
Chris@76 75
Chris@76 76 array cache_getRecentEvents(array eventOptions)
Chris@76 77 - cache callback function used to retrieve the upcoming birthdays,
Chris@76 78 holidays, and events within the given period, taking into account
Chris@76 79 the users time offset.
Chris@76 80 - used by the board index and SSI to show the upcoming events.
Chris@76 81
Chris@76 82 void validateEventPost()
Chris@76 83 - checks if the calendar post was valid.
Chris@76 84
Chris@76 85 int getEventPoster(int event_id)
Chris@76 86 - gets the member_id of an event identified by event_id.
Chris@76 87 - returns false if the event was not found.
Chris@76 88
Chris@76 89 void insertEvent(array eventOptions)
Chris@76 90 - inserts the passed event information into the calendar table.
Chris@76 91 - allows to either set a time span (in days) or an end_date.
Chris@76 92 - does not check any permissions of any sort.
Chris@76 93
Chris@76 94 void modifyEvent(int event_id, array eventOptions)
Chris@76 95 - modifies an event.
Chris@76 96 - allows to either set a time span (in days) or an end_date.
Chris@76 97 - does not check any permissions of any sort.
Chris@76 98
Chris@76 99 void removeEvent(int event_id)
Chris@76 100 - removes an event.
Chris@76 101 - does no permission checks.
