/**
|
||||
* @file
|
||||
* Defines date-related Views data and plugins:
|
||||
*
|
||||
* Date argument:
|
||||
* A generic date argument that has an option to select one or more
|
||||
* Views date fields to filter on, automatically adds them to the view,
|
||||
* and then filters the view by the value of the selected field(s).
|
||||
* The flexible argument will accept and evaluate most ISO date
|
||||
* and period formats, like 2009-05-01, 2008-W25, P1W.
|
||||
*
|
||||
* Date filter:
|
||||
* A generic date filter that has an option to select a
|
||||
* Views date field to filter on, with a choice of a widget to use
|
||||
* for the filter form and an option to set the default value to
|
||||
* a set date or something like 'now +90 days'. If the operator is
|
||||
* set to 'between' or 'not between' you can set a default value for
|
||||
* both the from and to dates.
|
||||
*
|
||||
* Current date argument default
|
||||
* Adds a default option to set the argument to the current date
|
||||
* when the argument is empty.
|
||||
*
|
||||
* Date navigation attachment
|
||||
* Navigation that can be attached to any display to create back/next
|
||||
* links by date, requires the date argument and uses the current
|
||||
* date argument default to set a starting point for the view.
