/**
|
|
* Dropdown field, created from a <select> tag.
|
|
*
|
|
* <b>Setting a $has_one relation</b>
|
|
*
|
|
* Using here an example of an art gallery, with Exhibition pages,
|
|
* each of which has a Gallery they belong to. The Gallery class is also user-defined.
|
|
* <code>
|
|
* static $has_one = array(
|
|
* 'Gallery' => 'Gallery',
|
|
* );
|
|
*
|
|
* public function getCMSFields() {
|
|
* $fields = parent::getCMSFields();
|
|
* $field = DropdownField::create('GalleryID', 'Gallery', Gallery::get()->map('ID', 'Title'))
|
|
* ->setEmptyString('(Select one)');
|
|
* $fields->addFieldToTab('Root.Content', $field, 'Content');
|
|
* </code>
|
|
*
|
|
* As you see, you need to put "GalleryID", rather than "Gallery" here.
|
|
*
|
|
* <b>Populate with Array</b>
|
|
*
|
|
* Example model defintion:
|
|
* <code>
|
|
* class MyObject extends DataObject {
|
|
* static $db = array(
|
|
* 'Country' => "Varchar(100)"
|
|
* );
|
|
* }
|
|
* </code>
|
|
*
|
|
* Example instantiation:
|
|
* <code>
|
|
* DropdownField::create(
|
|
* 'Country',
|
|
* 'Country',
|
|
* array(
|
|
* 'NZ' => 'New Zealand',
|
|
* 'US' => 'United States',
|
|
* 'GEM'=> 'Germany'
|
|
* )
|
|
* );
|
|
* </code>
|
|
*
|
|
* <b>Populate with Enum-Values</b>
|
|
*
|
|
* You can automatically create a map of possible values from an {@link Enum} database column.
|
|
*
|
|
* Example model definition:
|
|
* <code>
|
|
* class MyObject extends DataObject {
|
|
* static $db = array(
|
|
* 'Country' => "Enum('New Zealand,United States,Germany','New Zealand')"
|
|
* );
|
|
* }
|
|
* </code>
|
|
*
|
|
* Field construction:
|
|
* <code>
|
|
* DropdownField::create(
|
|
* 'Country',
|
|
* 'Country',
|
|
* singleton('MyObject')->dbObject('Country')->enumValues()
|
|
* );
|
|
* </code>
|
|
*
|
|
* <b>Disabling individual items</b>
|
|
*
|
|
* Individual items can be disabled by feeding their array keys to setDisabledItems.
|
|
*
|
|
* <code>
|
|
* $DrDownField->setDisabledItems( array( 'US', 'GEM' ) );
|
|
* </code>
|
|
*
|
|
* @see CheckboxSetField for multiple selections through checkboxes instead.
|
|
* @see ListboxField for a single <select> box (with single or multiple selections).
|
|
* @see TreeDropdownField for a rich and customizeable UI that can visualize a tree of selectable elements
