/**
|
|
* Implementation of hook_elements().
|
|
*
|
|
* Parameters for date form elements, designed to have sane defaults so any
|
|
* or all can be omitted.
|
|
*
|
|
* Fill the element #default_value with a date in datetime format,
|
|
* (YYYY-MM-DD HH:MM:SS), adjusted to the proper local timezone.
|
|
*
|
|
* NOTE - Converting a date stored in the database from UTC to the local zone
|
|
* and converting it back to UTC before storing it is not handled by this
|
|
* element and must be done in pre-form and post-form processing!!
|
|
*
|
|
* The date_select element will create a collection of form elements, with a
|
|
* separate select or textfield for each date part. The whole collection will
|
|
* get re-formatted back into a date value of the requested type during validation.
|
|
*
|
|
* The date_text element will create a textfield that can contain a whole
|
|
* date or any part of a date as text. The user input value will be re-formatted
|
|
* back into a date value of the requested type during validation.
|
|
*
|
|
* The date_timezone element will create a drop-down selector to pick a
|
|
* timezone name.
|
|
*
|
|
* #date_timezone
|
|
* The local timezone to be used to create this date.
|
|
*
|
|
* #date_format
|
|
* A format string that describes the format and order of date parts to
|
|
* display in the edit form for this element. This makes it possible
|
|
* to show date parts in a custom order, or to leave some of them out.
|
|
* Be sure to add 'A' or 'a' to get an am/pm selector. Defaults to the
|
|
* short site default format.
|
|
*
|
|
* #date_label_position
|
|
* Handling option for date part labels, like 'Year', 'Month', and 'Day',
|
|
* can be 'above' the date part, 'within' it, or 'none', default is 'above'.
|
|
* The 'within' option shows the label as the first option in a select list
|
|
* or the default value for an empty textfield, taking up less screen space.
|
|
*
|
|
* #date_increment
|
|
* Increment minutes and seconds by this amount, default is 1.
|
|
*
|
|
* #date_year_range
|
|
* The number of years to go back and forward in a year selector,
|
|
* default is -3:+3 (3 back and 3 forward).
|
|
*
|
|
* #date_text_parts
|
|
* Array of date parts that should use textfields instead of selects
|
|
* i.e. array('year') will format the year as a textfield and other
|
|
* date parts as drop-down selects.
