Field Type - Enum

Usage
Filter

Usage

The enum field type should be any text-like type or an ENUM in your database. This field type helps you narrow down the options for your admin users in a data set that you know will never change. The names of the seasons might be a good use of this field.

'season' => array(
    'type' => 'enum',
    'title' => 'Season',
    'options' => array('Winter', 'Spring', 'Summer', 'Fall'), //must be an array
),
//alternate method:
'season' => array(
    'type' => 'enum',
    'title' => 'Season',
    'options' => array(
        'Winter' => 'Cold, Cold Winter!',
        'Spring',
        'Summer' => 'Hot, Hot Summer!',
        'Fall'
    ),
),

In the edit form, an admin user will be presented with a select box showing the choices.

The options option lets you declare the choices that the user will see. You can either provide a simple array of strings, or if the key is a string, the key will be saved to the database while the value will be presented to the user.

Filter

The enum field filter works basically the same as the edit field. A user is presented with a select box which then narrows down the result set using whatever option is chosen.
