/**
|
|
* @file
|
|
* This file is used with the extended user field 'predefined list' type. It is
|
|
* invoked when the value field is 'timezones'.
|
|
*
|
|
* It is an example of an extended user field which access a predetermined list
|
|
* of key-pair values. In this example all the data is loaded into memory; for
|
|
* other applications the data may be read from a database, possibly with
|
|
* caching.
|
|
*
|
|
* The objective is to provide a uniform interface to such data.
|
|
*
|
|
* The class name must be the same as the file name - i.e. the list name
|
|
* prefixed with 'extended_'.
|
|
*
|
|
* The variable name must be 'timezones_list', and is an array of possible
|
|
* values, each of which is a value => text pair.
|
|
*
|
|
* The text is displayed in a drop-down; the value is returned.
|
|
*
|
|
* If function timezones_value() exists, it is called to create the displayed
|
|
* text.
