EntryEvents, a plugin for Movable Type

Requirements

This plugin requires the following perl modules:

  • DateTime
  • DateTime::Event::Ical
  • Date::Parse

Usage

The plugin needs to be enabled from the plugin settings screen for each blog on which you'd like to use it. To do this, navigate to Tools->Plugins for the blog you'd like to enable, click on EntryEvents, click on Settings, and check the "Show Events" checkbox.

Now the next time you create or edit an entry in that blog, you will see an Events widget in the right column. Clicking on the "Click to add event date" link will show a calendar.

To select a date/time for an event that only occurs once, click the date for which the event is scheduled and select a time from the dropdowns beneath the calendar. To navigate future or past months, click the « and » buttons next to the current month name in the header. Once a date has been selected for your event, you can add recurrence details by selecting the Recurrence checkbox below the calendar, which will show more options. Recurrence options are:

  • Every Day -- This event will recur at the selected time every day.
  • Every Week -- This event will recur at the same time on the selected day every week.
  • Every Month -- This event will recur on the same date every month (eg, an event on January 12 that recurs monthly will happen on February 12, March 12, etc.).
  • Every Year -- This event will recur on this date every year.
  • Custom... -- Selecting this will bring up further options for refining when an event recurs.

Selecting a particular Frequency for your custom recurrence will bring up a menu of options for that recurrence:

  • Daily -- For an event that recurs every X days.
  • Weekly -- For an event that recurs every X number of weeks on a particular day or days. For example, you can specify an event that recurs every Monday, Wednesday, and Friday every other week.
  • Monthly -- For an event that recurs on a particular day of the month that does not follow on the same date consistently. For example, an event may occur on the third Monday of every month. This will be pre-filled to reflect the date that you selected on the calendar.
  • Yearly -- For an event that recurs every X number of years on the same date every year.

For whichever form of recurrence you select, you must also specify a date that the recurrence ends in the Until box. This is pre-filled with a date a year from the selected event start.

Template Tags

Container Tags

<mt:Events /> -- This is a container tag that will retrieve all events for the blog in context. Optional parameters are:

  • start -- The timestamp to start events from, in YYYYMMDDHHMMSS format. Defaults to today.
  • days -- The number of days' worth of events data to load. Defaults to 7.
  • end -- The timestamp to grab events until, in YYYYMMDDHHMMSS format. If specified, will override the days argument.
  • no_end -- Set this to '1' to retrieve all events after start date. Specifying 'days' or 'end' will override the 'no_end' argument.
  • limit -- The maximum number of events to load and display.

An <mt:Events> tag with no parameters will default to displaying 7 days worth of events, starting with the time the template is published. This tag returns the entry objects associated with the events as well, so that one can retrieve the entry's title, description, tags, etc. in this context.


<mt:FeaturedEvents /> -- This is a container tag that will retrieve all featured events for the blog in context. Optional parameters are:

  • start -- The timestamp to start events from, in YYYYMMDDHHMMSS format. Defaults to the current date and time in the timezone set for the current blog in context.
  • days -- The number of days' worth of events data to load. Defaults to 7 unless 'no_end' argument is specified.
  • end -- The timestamp to grab events until, in YYYYMMDDHHMMSS format. If specified, will override the 'days' argument.
  • no_end -- Set this to '1' to retrieve all events after start date. Specifying 'days' or 'end' will override the 'no_end' argument.
  • limit -- The maximum number of events to load and display.

An <mt:FeaturedEvents> tag will load all (or up to limit=n) events marked "featured" starting on the date specified.


<mt:CategoryEvents /> -- This is a container tag that will retrieve all events for the category in context. Optional parameters are:

  • start -- The timestamp to start events from, in YYYYMMDDHHMMSS format. Defaults to today.
  • days -- The number of days' worth of events data to load. Defaults to 7.
  • end -- The timestamp to grab events until, in YYYYMMDDHHMMSS format. If specified, will override the days argument.
  • no_end -- Set this to '1' to retrieve all events after start date. Specifying 'days' or 'end' will override the 'no_end' argument.
  • limit -- The maximum number of events to load and display.
  • blog_id -- Blog ID of blog to retrieve events from. Defaults to blog ID of blog in context.
  • category -- Name of category to retrieve entry events for. Defaults to category in context. Error occurs if no 'category' argument is provided and no category is in context.
  • featured -- Set this to 1 and it will load featured events in the specific category.


<mt:EntryEvents> -- This is a container tag which will retrieve a list of the occurrences of the event associated with the current entry in context. Useful for retrieving the future dates of a recurring event. Optional parameters are:

  • start -- The timestamp to start events from, in YYYYMMDDHHMMSS format. If this is not passed, all recurrences of this event will be listed, including those in the past.
  • days -- Currently not supported. The number of days' worth of events data to load.
  • end -- The timestamp to grab events until, in YYYYMMDDHHMMSS format. If specified, will override the days argument.
  • limit -- The maximum number of events to load and display.


Template Loop Meta Variables

  • new_day -- When a new event date is encountered (the event date of the previous event is different from the event date of the current event), each of the above container tags sets the Movable Type variable 'new_day' to a value of '1'.

  • All of the above container tags support the standard template loop meta variables
    (__first__, __last__, __odd__, __even__, __counter__).


Function Tags

<mt:EventDate> -- Returns the date of the current instance of the event in context. If this is an event that only occurs once, it will return just that date. However, if it's a recurring event it will return the date of the recurrence in context (this tag will only work within one of the Events container tags).

The <mt:EventDate> tag recognizes a format attribute which may be used to control the format of the date displayed. The format attribute uses standard Movable Type date format specifiers per the Movable Type Date Formats documentation.

If no format attribute is specified a default format of "%A, %B %e at %l:%M %p" is used.


Conditional Tags

<mt:IfEventHasRecurrence> -- A conditional tag which returns true if the event is recurring, false if it is a one-off event.


<mt:IfEventFeatured> -- A conditional tag which returns true if the event is marked as "featured"



An example template using the above tags to display 7 days' worth of events and their details:

This week's upcoming events:<br />
<ul>
<mt:Events days="7">
    <li><mt:EntryTitle> -- on <mt:EventDate></li>
</mt:Events>
</ul>


Technical Stuff

Each event lives in a separate mt_entryevent table tied to the entries via an entryevent_entry_id link. This means that every event is a one-to-one relationship with an entry which means that future recurrences of an event will end up having the same comments. If you end up wanting events that have different comments from occurrence to occurrence, I would recommend creating new entries for each one.


mt-search Integration

'entry_events' query parameter

The EntryEvents plugin provides integration with mt-search and search provided by the FieldDay plugin via an 'entry_events' query parameter / form field. The 'entry_events' query paramter / form field may be used to filter (limit) search results to entries having an entry event date or an entry event recurrence date within a specified time period.

Format of 'entry_events' value: "start:YYYYMMDDHHMMSS,end:YYYYMMDDHHMMSS,days:nn"

All parameters (start, end, days) are optional, must be separated by a comma, and may be present in any order. Parameter name must be separated from parameter value by a colon (":").

  • start:
    Beginning of time period to look for entry events and event recurrences occurring on or after. Entry with event or event recurrence occurring exactly at start time will be returned in search results.

    Format: YYYYMMDDHHMMSS

    Default value: Current date/time using timezone from first blog being searched.

  • end:
    End of time period to look for entry events and event recurrences. Entry with event or event recurrence occurring exactly at end time will not be returned in search results.

    Format: YYYYMMDDHHMMSS

    Default value: (none)

    If both 'end' and 'days' are specified, 'days' overrides 'end'.

  • days:
    Number of days to search for events and event recurrences after 'start' date/time.

    Default value: 7 if neither 'days' nor 'end' are specified.

Examples:

  1. <input type="hidden" name="entry_events" value="start:20111004000000,days:1" />
    Result: Filter search results to entries with events or event recurrences occurring on or after 2011-10-04 12:00:00am and up to 1 day after (up to, but not including, 2011-10-05 12:00:00am).

  2. <input type="hidden" name="entry_events" value="start:20111004000000,end:20111005000000" />
    Result: Same as previous example - filter search results to entries with events or event recurrences on or after 2011-10-04 12:00:00am and up to, but not including, 2011-10-05 12:00:00am.

  3. <input type="hidden" name="entry_events" value="start:20111004000000" />
    Result: No 'days' and no 'end' parameters, so default 'days' value of '7' is used. Filter search results to entries with events or event recurrences occurring on or after 2011-10-04 12:00:00am and up to, but not including, 2011-10-11 12:00:00am.

Sorting of search results by entry event date ('SortByEntryEvent')

If search results have been filtered using the 'entry_events' query parameter / form field described above, search results may be sorted by the next entry event recurrence date (the next event recurrence date for an entry occurring on or after the 'start' date, but before the 'end' date). To sort search results by the next entry event recurrence date, include a SortByEntryEvent query parameter / form field, set to a value of '1'.

When SortByEntryEvent is enabled, sorting by next entry event recurrence date takes priority over any normal / default sort fields specified by a SearchSortBy query parameter / form field / configuration directive, and the normal / default sort fields become secondary sort fields used to order search results when two entries have the same event date.

Direction of sorting when SortByEntryEvent is enabled follows the setting of the SearchResultDisplay query parameter / form field / configuration directive.
