/**
|

|
|
* Private implementation of hook_widget().
|
| 12 |
|
|
*
|
| 13 |
|
|
* The widget builds out a complex date element in the following way:
|
| 14 |
|
|
*
|
| 15 |
|
|
* - A field is pulled out of the database which is comprised of one or
|
| 16 |
|
|
* more collections of start/end dates.
|
| 17 |
|
|
*
|
| 18 |
|
|
* - The dates in this field are all converted from the UTC values stored
|
| 19 |
|
|
* in the database back to the local time. This is done in #process
|
| 20 |
|
|
* to avoid making this change to dates that are not being processed,
|
| 21 |
|
|
* like those hidden with #access.
|
| 22 |
|
|
*
|
| 23 |
|
|
* - If values are empty, the field settings rules are used to determine
|
| 24 |
|
|
* if the default_values should be empty, now, the same, or use strtotime.
|
| 25 |
|
|
*
|
| 26 |
|
|
* - Each start/end combination is created using the date_combo element type
|
| 27 |
|
|
* defined by the date module. If the timezone is date-specific, a
|
| 28 |
|
|
* timezone selector is added to the first combo element.
|
| 29 |
|
|
*
|
| 30 |
|
|
* - The date combo element creates two individual date elements, one each
|
| 31 |
|
|
* for the start and end field, using the appropriate individual Date API
|
| 32 |
|
|
* date elements, like selects, textfields, or popups.
|
| 33 |
|
|
*
|
| 34 |
|
|
* - In the individual element validation, the data supplied by the user is
|
| 35 |
|
|
* used to update the individual date values.
|
| 36 |
|
|
*
|
| 37 |
|
|
* - In the combo date validation, the timezone is updated, if necessary,
|
| 38 |
|
|
* then the user input date values are used with that timezone to create
|
| 39 |
|
|
* date objects, which are used update combo date timezone and offset values.
|
| 40 |
|
|
*
|
| 41 |
|
|
* - In the field's submission processing, the new date values, which are in
|
| 42 |
|
|
* the local timezone, are converted back to their UTC values and stored.
