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
